I. GENERAL REVIEW
During the fiscal year ended March 31st, 1951, the Commission connected 4,075
new customers to its distribution-lines. This is over 600 more than the comparative
growth of new accounts in any previous year of the organization's five and one-half
years of operations and represents the addition of over sixteen newly served premises
every working-day. A total of 16,763 or 38 per cent of all customers served have
been brought the benefits of electricity through the efforts of the Commission, the
balance of the services having been acquired from other organizations.
The following table is a concise record of previously existing services acquired
and new connections made by the Commission since it began operations on August 1st,
1945:—

The British Columbia Power Commission was appointed on April 17th, 1945,
under the provisions of the " Electric Power Act," " to provide for improving the
availability and supply of electrical power." The operations of the Commission are
entirely self-supporting, the capital funds borrowed and the interest thereon having to
be repaid out of revenues received from the sale of power to its customers. When the
Commission was first established, the Province raised the necessary money for both
temporary and long-term loans, advancing it to the Commission for the acquisition and
construction of revenue-producing plants. Since 1949 the Commission has been raising funds in its own name, backed by the guarantee of the Province. Interest and
sinking-fund requirements on all borrowings have always been provided for in full. As
the debt incurred in the acquiring and building of all plant is being retired over a forty-
year period, it can be said that the customers of the Commission are becoming owners
of valuable assets. D 8

It will be observed that the growth recorded in the number of customers has been
accompanied by corresponding increases in generating plant (both number of units and
total capacity), in transmission- and distribution-line mileages, and in energy generated.
Continued expansion of the Commission's operations is expected in the future.
Construction work on the Clowhom hydro-plant to serve the Seechelt Peninsula is well
advanced and completion is expected before the end of the calendar year. Service
to the Ucluelet-Tofino area will be commenced soon after the close of the fiscal year,
bringing electric power to yet another area of the Province.
In view of the considerably larger fixed charges required to carry the additional
investment brought into operation during the year, the net operating surplus for the
year was highly gratifying. Increased revenues were responsible for producing a figure
very close to that resulting from the 1949-50 operations.
During the coming fiscal year heavy carrying charges on the Whatshan Development
will be levied against operations, which charges will not nearly be offset by fuel and
maintenance savings resulting from the close-down of the Kamloops and Barriere plants.
Consequently, until greater use of the available capacity of the Whatshan plant is made,
the net surplus position may be below the amount recorded this year.
Other factors which may have an adverse effect on the net operating result next
year are the higher expenses attributable to increased wages and salaries granted to offset
partially the upward cost-of-living trend. The probable reduction in the rate of capital
expenditure during the coming year will increase the proportion of administration and
general expense charged to operations. Added to these items is the fact that revenues
in the North Okanagan and Kamloops Power Districts will be adversely affected by the
introduction of promotional rates during the coming year, despite the fact that the
schedules in general may not bring about decreased charges to many customers.
In all areas, and particularly those where promotional rates have been in effect,
the consumption per customer continues to increase at a satisfactory rate while the
average charge for energy is gradually being reduced. The progress made in each power
district in this regard is portrayed in the table " Statistics Relating to the Supply of
Electrical Energy " for the past five years. Twenty-two out of the present twenty-five
power districts are now operating under the uniform rate structure introduced by the
Commission in 1946.
In the sphere of public relations a programme of educational advertising by the
Commission was commenced during the fiscal year. A quarterly house organ—
Progress—issued first in January, 1950, was published regularly and was well received
by employees. The wide and ever-growing demand for copies indicates the advisability
of continuing this venture, perhaps at more frequent intervals. The Commission is
indebted to the Province's daily and weekly newspapers for excellent coverage of
its operations.
The administration building in Victoria was completed before the close of the
fiscal year, the staff moving into the new quarters at the end of January, 1951. This
centralization brought about a reorganization between head office and power district
staffs, producing greater efficiency and economy by eliminating the need for regional
offices at Nanaimo and Vernon.
This Sixth Annual Report describes in detail the year's activities under the
functional headings of Legal, Construction, Operation, Surveys and Investigations, and
Financial. D 12

II. LEGAL
1. LEGISLATION
Two Acts concerning the Commission were passed at the 1951 Session of the
Legislature and are described here, although actually introduced after March 31st:—
(a) "Electric Power Act."—This Act was amended to raise the borrowing
limitation from $45,000,000 to $60,000,000. Other amendments concerning financial provisions of a minor nature were also passed.
(b) "Hope and Lillooet Electrical Systems Sale Act."—This Act authorized
the Commission to sell all of its electrical plant at the Villages of Hope
and Lillooet, and adjacent areas, together with its electrical transmission-
line from Jones Creek to Hope, to British Columbia Electric Company,
Limited, at a price to be approved by the Lieutenant-Governor in Council.
It is provided that this price shall not be less than the full amount of
the Commission's investment therein, less the sinking-fund reserves
and the maintenance and renewal reserves provided by the Commission
therefor.
2. COMPENSATION FOR EXPROPRIATED PROPERTIES
In the last Annual Report the Commission reported on the findings of the Honourable Mr. Justice Wilson in the compensation appeals in respect to the expropriated
properties of West Canadian Hydro Electric Corporation, Limited; Nanaimo-Duncan
Utilities, Limited; and Columbia Power Company, Limited. At that time (March
31st, 1950) it was not known whether or not appeals would be taken from these
findings. No appeals were taken. The compensation awarded has been paid to all
companies in full, and all matters pertaining to these expropriations and the subsequent
proceedings are concluded, except for the matter of certain costs claimed by Nanaimo-
Duncan Utilities, Limited. The Honourable Mr. Justice Wilson decided that the
Registrar properly taxed these costs in favour of the company. An appeal from that
decision was made by the Commission and is now pending before the Court of Appeal.
3. ACQUISITION OF ELECTRICAL PROPERTIES
During the year the Commission acquired only one operating property, the electrical
system owned by the Corporation of the City of Merritt. This plant was purchased by
the Commission for operation on December 31st, 1950, at which date there were 473
customers.
4. RIGHTS-OF-WAY AND PROPERTY ACQUISITIONS
During the fiscal year the following progress was made in the acquisition of right-of-
way easements required for the Commission's main transmission systems:—
(1) The 132-kv transmission-line from the Whatshan Development at Needles
to the Vernon substation required the acquisition of a right-of-way 130
feet in width over a distance of 67 miles. The line crossed 226 parcels
of land registered in the names of 85 owners. The negotiations with these
owners for the necessary right-of-way were commenced on February 1st,
1950, and settlements with 79 owners have now been completed. The
remaining 6 claims are in various stages of completion.
(2) In the course of the year, 3 of the 8 outstanding right-of-way claims on
the 63-kv transmission-line from Vernon to Kamloops were completed.
The 5 remaining claims on this line, out of a total 224 parcels of land
registered in the names of 114 owners, are at this date in various stages
of negotiation. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 19
(3) In the course of the year, 8 of the 12 outstanding right-of-way claims on
the 132-kv transmission-line from the John Hart plant to Nanaimo and
Port Alberni were completed. There remains 4 claims on this line, out of
a total of 414 parcels of land registered in the names of 115 owners, yet to
be finalized, and negotiations on these are in various stages of completion.
(4) Survey plans for the Duncan to Lake Cowichan 60-kv transmission-line
were submitted for approval by the Land Registry Office on July 31st,
1950, and negotiations for the necessary easements by way of right-of-way
commenced. This line required a right-of-way 80 feet in width over some
13 parcels of land registered in the names of 5 owners.
(5) Survey plans for the Vernon-Armstrong 60-kv transmission-line were
registered on November 2nd, 1950, and the acquisition of the necessary
easements by way of right-of-way over private properties commenced.
This line required the acquisition of a right-of-way 60 feet in width over
a distance of 5.84 miles, affecting 28 parcels of land registered in the
names of 27 owners. By the end of the fiscal year easements over 23 of
of the parcels had been completed with 23 owners, and negotiations with
the remaining 4 are nearing completion.
(6) Survey plans required in connection with the acquisition of easements, by
way of right-of-way, over private property for the 138-kv transmission-line
from the John Hart generating plant to the Elk Falls Company's Sulphate
Mill at Duncan Bay have been completed and submitted for approval by
the Land Registry Office. The preliminary work of contacting the private
property owners, prior to acquiring the necessary easements, has been
concluded and the clearing is now under way.
(7) Survey plans for the 60-kv transmission-line from the Commission's
substation at Nanaimo to the MacMillan pulp-mill at Cedar, Vancouver
Island, were submitted to the Land Registry Office, and negotiations for
the required easements by way of right-of-way were commenced.
(8) A preliminary survey plan covering the first 9 miles of the Clowhom Falls-
Sechelt 63-kv transmission-line right-of-way has been furnished, and the
work of contacting the private property owners, prior to entry, has been
completed, as has the cruising of the merchantable timber on the right-
of-way.
In rural areas throughout the Province, distribution-line extensions necessitated the
acquisition of some 26 easements by way of right-of-way over private lands.
The purchase and settlement of claims involving some 200 acres of privately owned
lands, required in connection with the Whatshan Development, were completed during
the course of the year. One of these claims involved the relocation of a tourist and
fishing camp located on the shores of Whatshan Lake.
The following applications were launched under the " Navigable Waters Protection
Act," in connection with overhead and under-water cable crossings of navigable rivers
and lakes:—
(1) Overhead cable crossing of a portion of Salmon Arm, Seechelt Inlet,
required for the Clowhom Falls-Sechelt 60-kv transmission-line right-
of-way.
(2) Overhead cable crossing of the North Thompson River at Kamloops,
required for the 12,000-v distribution-line extension to improve the
availability and supply of power for the Kamloops and North Kamloops
areas.
(3) Under-water cable crossing of Okanagan Lake, between Kelowna and
Westbank, required for the 6,900/12,000-v extension to serve Westbank,
Peachland, and adjacent areas. D 20 " ELECTRIC POWER ACT *'
(4)  Under-water cable crossing of Cormorant Channel, from Alert Bay to
Malcolm Island, to serve the residents of Sointula.
Other overhead cable crossings of a more minor nature were applied for on the
following rivers:—
(1) Courtenay River at Courtenay.
(2) South Thompson River at a point 4 miles east of Pritchard.
(3) South Thompson River from a point in District Lot 265, Range 15,
Township 19, across from Campbell Creek.
Substation sites were acquired at the following places:—
(1) Lake Cowichan, from Unity Hall Holding Society.
(2) Courtenay, from British American Oil Company, Limited.
(3) Ladysmith, from the City of Ladysmith.
(4) Needles, substation and power-house site, from the Crown, Provincial.
(5) Puntledge, from Canadian Collieries (Dunsmuir) Limited.
5. PROPERTY SALES
The following lands and buildings, which were surplus to requirements, were
disposed of:—
(1) Jinglepot hydro-plant buildings and lands.
(2) Nanaimo hydro and steam plant buildings and lands.
(3) Lots 6 and 7, Block 2, of Suburban Lot 24, Plan 466, Nanaimo District.
(4) Lot 10 and easterly 40 feet of Lot 5, Block 42, Section 1, Nanaimo

(7) Two cabins and outbuildings, Whatshan Lake.
6. CONTRACTS
Contracts have been drawn and settled covering all major construction projects
undertaken during the year, together with numerous contracts for the supply of plant
and equipment required in connection therewith.
Apart from ordinary service contracts, agreements were completed for the supply
of industrial power in power districts and for the supply of street-lighting service in
certain incorporated villages and unorganized communities.
On January 16th, 1951, the Commission entered into an agreement with Northland
Utilities (B.C.) Limited for the supply of natural gas at Dawson Creek. The source of
supply is in the Province of Alberta, the gas being piped across the inter-Provincial
boundary. The Commission, as a consequence of this agreement, is now using natural
gas as fuel in the generating plant at Dawson Creek.
7. WATER LICENCES
Water licences held by the Commission for storage and diversion purposes on the
following rivers and creeks were cancelled at the Commission's request, as of March
9th, 1951:—
(1) Final Licence No. 5091, Coal Creek.
(2) Final Licence No. 7941, McCarrigle Creek.
(3) Final Licence No. 3328, Millstone River.
(4) Final Licence No. 11754, Millstone River.
(5) Final Licence No. 7942, storage licence issued in connection with Final
Licence No. 7941.
(6) Final Licence No. 5090, storage licence issued in connection with Final
Licence No. 3328.
(7) Final Licence No. 10134, Seton Lake Creek. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 21
8. INSURANCE
Comprehensive insurance coverages on all phases of the Commission's operations
were maintained in force. There were certain rearrangements and deletions of some
types of coverage effected in order to meet the needs of the Commission.
No major claims under any of the coverages were experienced during the course of
the year's operations, with the exception of one property-damage claim in the sum of
$500, which has been adjusted to the satisfaction of the claimant. There were numerous
other small claims under the fleet and property-damage coverages, which were reported
and satisfactorily settled.
The result of the safety programme, which was instituted last year in connection
with the Commission's motor-vehicle fleet, has been very gratifying, as the accident rate
this year has shown an appreciable decline over former years. D 22 " ELECTRIC POWER ACT "
III. CONSTRUCTION
1. PRODUCTION PLANT
Burns Lake
A diesel-electric generating unit of 250-kw capacity, obtained by transfer from
Quesnel, was installed in the new power-house built last year. This machine, together
with the two previously installed, provides a total capacity of 450 kw. In addition two
portable units, each of 50-kw capacity, were made available during the winter months.
Clowhom Falls
Construction of a hydro-electric power development at Clowhom Falls, consisting
initially of two 1,500-kw generating units, was begun during the late summer of 1950.
The general contract covering construction of a dam, pipe-line piers, power-house, and
operators' dwellings was awarded to Dawson, Wade & Company, Limited, on September
21st, 1950, and work was commenced promptly thereafter. By the end of the fiscal year
the dam and pipe-line piers had been completed, work on the operators' dwellings was
well advanced, and excavation was proceeding for the power-house.
Delivery of generators, turbines, transformers, and other equipment is scheduled
for the late summer and autumn of 1951, and it is expected that the plant will be ready
for operation by November, 1951.
Dawson Creek
A new diesel-electric generating unit of 600-kw capacity was installed to replace
a 240-kw unit of advanced age. The new machine is a dual-fuel unit (it can burn either
oil or gas) and is similar to the machine installed the previous year. Generating capacity
now available at Dawson Creek is 1,880 kw.
Houston
A temporary building was constructed and three 30-kw portable diesel-electric
generating units were installed on release from Burns Lake. Capacity available at
Houston is, therefore, 90 kw, which was brought into production on May 10th, 1950.
Lillooet
Construction of a new building to house diesel-electric generating equipment was
completed, but no machinery was installed.
Merritt
The Merritt generating plant was acquired from the City of Merritt, and was taken
under Commission operation on December 31st, 1950, by which time the first of three
projected 250-kw diesel-electric generating units was in operation. The plant capacity
at the end of the fiscal year was 250 kw, with installation of the second and third units
in progress.
Quesnel
Two new diesel-electric generating units, each having a capacity of 600 kw, were
installed during the year. These machines released two 250-kw units, giving a net
increase of 700 kw.   The generating capacity of the Quesnel plant is now 1,450 kw.
Sechelt
The generating capacity of the Sechelt plant was increased from 560 kw to 810 kw
by the installation of a diesel-electric set of 250-kw capacity. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 23
Power-house site and falls at head of Salmon Arm, Clowhom Development.
Operators' dwellings and penstock forms, Clowhom Development. D 24 " ELECTRIC POWER ACT "
Smithers
A new diesel-electric generating unit of 560-kw capacity was installed to replace
a 250-kw machine, increasing the plant's capacity from 750 kw to 1,060 kw. At the end
of the fiscal year, installation of a second 560-kw unit was in progress.
Terrace
A portable unit of 50 kw was in operation during the peak-load winter months in
addition to the 350 kw of installed capacity of this plant.
Tofino
Rehabilitation of the Tofino generating plant, acquired from War Assets Corporation, was carried out during the year. Generating capacity of 300 kw is now available
in three diesel-electric units of 100 kw each.
Whatshan
Even though concrete lining was required in a greater proportion of the 12,500-foot
tunnel than appeared likely at an earlier stage, all work on the tunnel, including final
closure and provision of the concrete plug at the Arrow Lake end, was complete by the
end of the fiscal year, leaving only some under-water excavation on Whatshan Lake near
the tunnel entrance. Mechanical and electrical equipment was installed, ready for testing
and placing in operation.
The initial installation in this plant consists of two 11,250-kw generating units.
Provision is made for later adding two more units of the same size.
Williams Lake
Capacity of the plant was increased from 575 kw to 775 kw by the installation of
a new diesel-electric unit of 250-kw capacity, replacing a 50-kw set which had outlived
its usefulness.  D 26

2. TRANSMISSION PLANT
Vancouver Island System
Capacity of the Nanaimo substation was increased during the year by the installation
of three 5,800-kva 138/69-kv transformers, bringing the total capacity of this substation
to 34,800 kva.
Circuit-breakers, disconnects, and metering and control equipment were installed
to provide interconnection with the British Columbia Electric Railway Company, Limited,
138-kv line from Nanaimo to Victoria. This equipment commenced operation when the
Nanaimo-Victoria line was energized on October 1st, 1950.
A 69-kv oil circuit-breaker was installed at the Nanaimo substation in the Pine
Street line.
At the close of the year, construction was well advanced on a transmission-line from
Duncan to Lake Cowichan, which, when completed, will make energy from John Hart
Development available to the Lake Cowichan Power District and intervening territory.
At the end of the year this line had been energized as far as Summit, which area was then
receiving service; it was designed and built for 60-kv operation but will be operated in
the immediate future at 23 kv.
Construction has commenced on a 60-kv substation at Ladysmith. designed to serve
the Ladysmith area and to relieve load conditions at Nanaimo's Pine Street substation.
Three 5,000-kva 138/13.8-kv transformers were installed on a site adjacent to the
Puntledge hydro-electric generating station of Canadian Collieries (Dunsmuir) Limited. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 27
A short length of double-circuit 138-kv line was built to connect this transformer bank
to the 138-kv lines from John Hart Development and the new substation was energized
on October 20th, 1950. Sixty-cycle power thus became available to the Comox Valley
area.
To meet the requirements of a contract covering supply of energy to Elk Falls
Timber Company, Limited, at Duncan Bay, a double-circuit transmission-line of wood-
pole construction from John Hart Development to Duncan Bay, together with terminal
equipment at each end, was designed, and material, including two 20,000-kva three-phase
transformers (132/13.8 kv), with on-load tap changers, was ordered for late 1951
delivery.
Vernon-Kamloops
A 1,500-kva substation at Westwold was completed and placed in service. This
station takes power from the 63-kv Vernon-Kamloops line and supplies the new
6.9/12.0-kv distribution system serving Falkland, Westwold, and Monte Lake.
Construction of a 63-kv substation at Lumby allowed supply to that area to be
transferred from the 23-kv circuit, with resultant improvement in voltage conditions both
at Lumby and elsewhere on the 23-kv system.
Six and nine-tenths miles of 63-kv transmission-line were constructed from a point
on the Vernon-Kamloops line near O'Keefe's Ranch, north of Vernon, to Armstrong, and
a 1,500-kva substation at Armstrong approached completion.
Whatshan-Vernon
The 138-kv transmission-line from Whatshan to Vernon was completed during the
year and, while not in service, was energized to provide power-factor correction for the
North Okanagan system.
Minor work only remained to be carried out on the Whatshan and Vernon terminals
of the line. At the Whatshan terminal two 12,500-kva three-phase transformers have
been installed and at the Vernon terminal three 8,333-kva 138/63-kv transformers are
ready for service, with a fourth available as a spare. Wave-traps and control cable for
use with carrier-current communication have been installed.
Clowhom-Sechelt
Plans are complete and material has been ordered for the construction of a 63-kv
" H-frame " transmission-line from Clowhom Falls Development to Sechelt; surveys of
the required right-of-way approach completion and clearing of the initial section is in
progress.
Transformers for the Clowhom and Sechelt terminals have been ordered for delivery
in mid-1951. D 28

IV. OPERATION
1. PRODUCTION
Rapid growth in many power districts, particularly Dawson Creek, Quesnel, and
Smithers, led to a situation where it was no longer economically sound practice to keep
adding smaller generating units to meet rapidly growing demands. Consideration, therefore, had to be given to installation of units of greater capacities. Another factor bearing
on the matter was that natural gas was already available at Dawson Creek and might be
available in the not too distant future at Quesnel.
It was, accordingly, decided to install at both Dawson Creek and Quesnel dual-feed
engines which could be operated either by fuel-oil or natural gas. Two such units were
installed at Dawson Creek during the past two years and for the last three months of the
current fiscal year have been operated by natural gas. It is still too early to give definite
figures regarding comparative costs, but it is known that cost per kilowatt-hour generated
has been reduced considerably.
A threatened shortage of generating capacity in the North Okanagan and Kamloops
Power Districts pending the completion of the Whatshan hydro-project was met by
connecting all generating-stations—Shuswap Falls, Barriere, and Kamloops steam plant—
and operating them in parallel. A similar connection was also maintained at all times
with the West Kootenay Power & Light Company, Ltd. This method of operation
proved invaluable on many occasions, not only during a temporary breakdown, but as
a flexible means of providing quick relief during peak-load periods on any part of the
system. A contributing factor in the threatened shortage was the long, dry period in the
fall of 1950, which reduced water-storage at both Sugar Lake and the Barriere Lakes
well below normal.
Purchase of blocks of power from the West Kootenay Power & Light Company, Ltd.,
was essential in order to build up water-storage reserves.
On Vancouver Island, purchase of power from the Hillcrest Lumber Company, Ltd.,
to supply the Lake Cowichan Power District was continued, pending completion of a new
60-kv transmission-line from Duncan, which will provide direct connection with the Vancouver Island transmission system.
Comox Valley and Campbell River Power Districts were partly supplied with 25-
cycle power, purchased from Canadian Collieries (Dunsmuir), Limited, in progressively
diminishing amounts as conversion from 25-cycle to 60-cycle frequency proceeded in
these districts.
Interconnection at 138 kv with the British Columbia Electric Railway Company
system was inaugurated on October 5th, 1950, and this added demand, together with
that of the MacMillan mill at Cedar, increased maximum loads at the generating-station
from 25,000 kw to 45,000 kw and resulted in the energy output from the John Hart
generating-station being more than double that of the preceding year.
Townsite premises at the John Hart plant have been improved considerably during
the year, including levelling, grading, building roads, laying lawns, and planting shrubbery. This work was carried out with the expert advice and assistance of officials of
the Provincial Parks Service.
Increases in the output of other generating-stations were substantial, as can be
observed by reference to the following table of power generated.
The sum of the demands upon all sources of purchased power was 4,460 kw and,
accordingly, the system capacity for the past two years may be compared as follows:—

2. TRANSMISSION
132-kv System
The 132-kv system on Vancouver Island was completely interrupted momentarily
on two occasions. During a severe wet-snow storm in mid-January the conductors of
these lines accumulated a heavy loading, which was responsible for one interruption,
the other being due to some unknown cause. Construction activities at Nanaimo and
Courtenay resulted in several planned interruptions to these lines.
The 132-kv connection with the British Columbia Electric Railway Company,
Limited, Victoria system was placed in operation on October 5th, and the new Courtenay
132-kv substation was connected on October 19th, 1950.
Considerable attention was given to the improvement of access roads, the abandonment of certain logging-roads by the operators adding to the problem of maintenance of
the 132-kv system. Results of chemical spraying on the 132-kv right-of-way have been
satisfactory, and an additional 14 acres were sprayed during the past year.
Regular line patrols and inspections were carried out, maintenance including replacing a number of broken insulators and conductor repairs made by means of preformed
armour rods. Some evidence of loose tower-bolts on the 132-kv line towers was noted
and corrected. All high-voltage bushings were given an initial grading and the characteristics of each recorded for future reference.
During the late fall and through the winter months, the newly constructed 132-kv
line from the Whatshan Development to Vernon was energized at 60 kv to provide
power-factor correction for the North Okanagan system, and, during the shortage of
power, to facilitate transferring energy from the West Kootenay Power & Light Company,
Limited.
Sub-transmission Systems
The few interruptions on the sub-transmission systems were, with two exceptions,
only of short duration.
The exceptions occurred during a severe snow-storm on January 19th, with two
interruptions of several hours' duration to the line supplying a pulp-mill near Nanaimo.
This line had been newly constructed and all dangerous trees had not been removed.
The F/M radio communication system on Vancouver Island has operated well
during the year. A new station was added at Courtenay and a F/M radio link has also
been established with the British Columbia Electric Railway Company, Ltd., at Victoria.
A preliminary radio survey has been made in the Sechelt area in preparation for the
installation of a radio link to Clowhom Falls generating-station.
The removal of additional dangerous trees along all transmission-lines continued,
and, on the older subtransmission-lines, pole stubbing and other repairs were made.
A thorough maintenance and inspection programme was carried out on all substation and switchyard equipment. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 41
3. DISTRIBUTION
As at March 31st, 1951, twenty-five power districts were being operated by the
Commission, Merritt and Houston having been added during the year. Merritt was
acquired as a result of negotiations with the City Commission of Merritt. Houston was
an entirely new installation by the Commission.
Loads continued to grow in every section of the'Province, resulting in the necessity
of increasing both transformer and conductor capacities. To meet increased demands,
it was also necessary to expand distribution systems, in many instances on a fairly large
scale. This was particularly true in the North Okanagan, Nanaimo-Duncan, Kamloops,
Dawson Creek, Smithers, and Quesnel Power Districts.
Industrial development in the northern part of the Province, particularly activities
connected with the Celanese Company at Port Edward and the Alcan hydro-project at
Kitimat, is having its effect upon the economic life of many smaller towns between- Prince
George and Prince Rupert. The Smithers-Telkwa line was designed and constructed
for ultimate 6,900/12,000-volt service, in order that anticipated future loads could be
supplied from the Smithers generating-station, although initial operation was at the
Smithers voltage of 2,300/4,000. With the expected development of the area materializing, conversion to the designed voltage was made necessary and effected during the
year. Increasing activity, particularly in relation to forest products, indicates that further
expansion of distribution systems from Terrace eastwards will be necessary in order to
meet both domestic and industrial requirements.
An interesting feature of the 1950-51 operation was the frequency conversion of
the Comox Valley and Campbell River systems from 25 cycle to 60 cycle. The Campbell River Power District has been completely changed to 60-cycle frequency. In the
Comox Valley area, comprising the towns of Courtenay, Cumberland, Comox, and Roy-
ston, conversion was started in August, 1950, and by March 31st, 1951, a total of 1,690
services had been converted from 25- to 60-cycle power. As at the end of the fiscal
year, all the above customers were being served from the John Hart generating-station,
either direct or through the new 138-kv 15,000-kva transmission substation near
Courtenay.
The conversion was carried out with little trouble and the least possible inconvenience to customers. This was made possible by a carefully planned programme and
the use of two portable diesel-electric generating units as temporary sources of 60-cycle
power.    From 25 to 50 services per day were converted.
It was at first thought that all 25-cycle meters recovered under the conversion would
be a total loss, as there are few systems left not operating on standard frequency.
However, a number of these meters were experimentally converted to 60-cycle operation
by the Commission's meter department and have been approved by the Bureau of
Standards, Ottawa. This work of conversion will be continued and will lead to considerable saving.
A test laboratory for linemen's rubber gloves was set up early in the year at
Nanaimo, and a schedule for routine testing of all rubber gloves is in operation.
Winter weather conditions were generally favourable and accidental interruptions
were below normal. D 42

4. RATE SCHEDULES
During the year, two far-reaching amendments to the Commission's general promotional rate structure were introduced, which had the effect of reducing monthly bills
for commercial and, to a lesser extent, for residential service.
In the commercial field where the demand rating exceeds 5 kw the billing demand
has been reduced to 75 per cent of the measured demand. Previously, accounts were
billed on the measured demand itself so that an account previously billed at 8 kw
would now pay on the basis of 6 kw. In the residential field, although households
with electric ranges were normally billed on the basis of 3 kw, the Commission had the
right to charge according to the actual maximum demand, a policy only adopted if
considerable other equipment were added. Under the new provision, where the
measured demand exceeds 8 kw the billing demand is definitely established as that
maximum reading less 5 kw. It is believed such decreases will encourage further growth
in these classifications despite the phenomenal record shown elsewhere in these pages.
Other decisions affecting general rates had to do with the broadening of the former
summer-service classification to include any seasonal load. Service is now only limited
to six consecutive months or less ending within the fiscal year. Also amended was
the power-service contract, which now requires that customers for this type of service
shall pay the cost beyond one span of the line required to serve them. This stipulation
ensures that the Commission will not have large sums of capital employed in unremuner-
ative extensions.
Promotional schedules were made available in the Merritt Power District, acquired
during the year.    In addition, the rates for the Ucluelet-Tofino Power District, where REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51
D 43
construction was still under way at the end of the fiscal year, were also established.
With the commencement of the 60-cycle conversion programme in the Comox Valley
Power District, promotional rates were approved during the year, and as customers are
switched over from the 25-cycle system they automatically come under the new schedules.
By March 31st, 1951, 1,690 services, or 58 per cent of the 2,900 customers in the
district, were operating on the new frequency.
Following the completion of the conversion programme in the Campbell River
Power District, the former rates were abolished, so that on Vancouver Island all
customers will be on Regulation No. 5 as soon as the present switch-over in the Comox
Valley is completed.
Staff buildings, Whatshan Development, on shore of Lower Arrow Lake.
In the Interior, rate studies were made in the North Okanagan and Kamloops
Power Districts, preparatory to adopting promotional schedules after the completion of
the Whatshan Development. Up to the present the use of electricity in these two areas
could not be encouraged by more attractive rates, since the available power was
insufficient to permit such a course. However, both these power districts have extensions where Regulation No. 5 is in effect. These areas are the community of Chase,
together with the line from Kamloops; all part of the Kamloops Power District; and
the Falkland-Westwold-Monte Lake area of the North Okanagan Power District,
All other power districts, with the exception of Lillooet, whose sale to B.C. Electric
interests is being discussed, are operating on promotional rates for all classes of service,
as indicated in the following tables. Including Ucluelet-Tofino, which was not yet in
operation at the close of the fiscal year, promotional rates have therefore been approved
for general use in twenty-three out of twenty-six power districts. D 44

V. SURVEYS AND INVESTIGATIONS
1. POWER PROJECTS
A report on hydro-electric power possibilities on Quesnel River was submitted
to the Government early during the fiscal year, recommending an initial development
at Little Canyon, about 16 miles from Quesnel. Owing to possible interference of a
power development at this location with salmon migration, certain surveys to supplement information previously obtained on the North Branch of Quesnel River were made
later during the year. The results of these surveys confirmed that development on this
branch would be considerably more costly per horse-power than at Little Canyon.
In accordance with the long-range programme for development of power-generation
facilities on Vancouver Island, to keep pace with the expected industrial expansion up
to 1960, provision for the third phase of the John Hart plant is now in the planning
stage. This comprises the construction of a third pipe-line and surge-tank and installation of the two final 28,000-horsepower units (Nos. 5 and 6). It will also be necessary
to provide for additional storage to ensure an adequate water-supply. The Commission's
consulting engineers, H. G. Acres & Company, recommended that development of
Buttle Lake as a storage-reservoir be undertaken and completed by the end of 1954.
Applications were, accordingly, submitted near the close of the fiscal year to the Government requesting authorization to proceed with these developments.
Provisions for generating facilities to supply the communities at Fort St. James, at
Queen Charlotte City and Skidegate, and at Atlin were investigated.
2. TRANSMISSION PROJECTS
The 60-kv transmission system on Vancouver Island, which now extends from
Nanaimo southwards to Duncan, has been the subject of review. It has been decided
to install a new 5,000-kva 60/23-kv substation at Ladysmith, and plans have been
developed for future increases in capacity at the existing Nanaimo and Duncan substations.
General surveys were carried out covering the location of a second 60-kv circuit
between Vernon and Kamloops, passing through Armstrong, Enderby, Salmon Arm, and
Chase. Detailed plans were developed for the two most urgently required sections of
this line; namely, a connection to Armstrong to relieve the existing load on the 33-kv
transmission-line from Shuswap Falls, and the section between Monte Creek and Chase.
Means for the transmission of power from the Whatshan generating-station northward to Nakusp were investigated.
3. DISTRIBUTION PROJECTS
Surveys were made during the year for a distribution project to serve communities
situated at Needles, Edgewood, and Fauquier near the Whatshan generating-plant.
The area extending 12 miles southward from Revelstoke was also investigated.
Survey work was also carried out in connection with possible extensions to Gabriola
and Quadra Islands, to 150-Mile House near Williams Lake, to Fort St. James, to Yahk-
Kingsgate, and on the Queen Charlotte Islands. Detailed plans were made of the
Ladysmith distribution system, acquired during the preceeding year, as well as of the
Merritt system, recently brought under Commission operation. Designs for the complete reconstruction of these systems were also developed.
Following conclusion of a contract providing for interchange of power between
the Commission and the West Kootenay Power & Light Company, Ltd., at Kelowna,
a survey was made covering provision for an under-water cable across Okanagan Lake
near Kelowna, together with a 6.9/12-kv distribution circuit to serve Westbank and the
area between Westbank and the end of the cable-crossing. Surveys were also made
in respect of a service to a " Veterans' Land Act" settlement now being developed in
this area. D 54 " ELECTRIC POWER ACT "
VI. FINANCIAL
The following statements are presented to show the financial position of the Commission at March 31st, 1951, and the result of the financial operation of the Commission
for the year ended on that date. Comment is made hereafter on certain items appearing in these statements:—
Statement 1.—Balance-sheet,
Statement 2.—Financial Summary—Revenue and Expenses.
Statement 3.—Power Distribution—All Districts:   Summary of Revenue and
Expenses.
Statement 4.—Power Distribution by Districts:
(a) Revenue and Expenditure
(b) Stabilization Reserve.
Statement 5.—Plant and Related Reserves.
Statement 6.—Construction Work in Progress.
Statement 7.—Maintenance and Renewals Reserve.
STATEMENT 1
Capital Assets
Plant Values by functions shown on this balance-sheet are supported by details
given in Statements 5 and 6.
During the past year, certain Inactive and Abandoned Plant costs were segregated
from Plant in Operation and are shown separately in the balance-sheet. In addition,
other costs of Abandoned Plant have been written off to the Maintenance and Renewals
Reserve. These costs relate largely to the original expropriations and some further
segregation remains to be completed. Retirements of a more current nature were
charged to the Maintenance and Renewals Reserve in the past year.
Final settlement for the original expropriated properties was made in the past year
according to the Court Awards. The estimated liability shown in previous balance-
sheets has been eliminated and the required adjustments recorded in Plant in Operation
and Acquisition Adjustment Account. The Acquisition Adjustment Account was
charged with that portion of the amount paid by the Commission for acquired plant
in excess of the Commission's estimate of plant value. Interest paid on the Court
Awards has been charged to Interest and Contingency Reserves, where full provision
had previously been made.
The total of plant and equipment in operation includes work in progress capitalized
at March 31st, 1951, in the amount of $2,259,877.94.
Current Assets
Accounts receivable have been reduced by the reserve for bad debts which is
deemed adequate in the amount of $12,182. Included in Accounts Receivable Other
is the amount of $14,529.02, representing accounts which are over ninety days old.
Inventory values have increased considerably, in line with increased operating and
construction requirements.   Physical inventories were taken at March 31st, 1951.
Deferred Charges
The write-off of organization and preliminary expense on a ten-year basis continued as in the past years, the amount of $15,906.03 being amortized.
Bond discount was written down according to the term of each issue. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 55
Sinking Fund
The full requirement of Sinking Fund as provided for in the " Electric Power Act "
is on deposit with the Minister of Finance, Province of British Columbia. It has not
been necessary to take advantage of deferments previously granted.
Long-term Liabilities
An advance of $60,000 under the " Central Interior Development Act" was
received to cover costs incurred on preliminary surveys of the Quesnel River. No
general advances were received from the Province of British Columbia in the year under
review.
All interest and discount charges in connection with Provincial advances have
been met in full. On November 1st, 1950, the Commission issued and sold a
$6,000,000 3-per-cent bond issue maturing in 1968. The net amount received from
this issue was used to repay temporary borrowings expended for the capital purposes
of the Commission. Full provision has been made for interest and discount on such
issues.
Borrowings by the Commission on both long-term and temporary bases are
guaranteed as to interest and principal by the Province of British Columbia.
Current Liabilities
The major liability in this section is the bank loan and overdraft, interest being
paid or accrued to March 31st, 1951.
The borrowing limitation of the Commission at March 31st, 1951, under the terms
of the " Electric Power Act," was $45,000,000. This amount had not been exceeded at
that date.    The borrowing limitation has subsequently been increased to $60,000,000.
There has been a major reduction since April 1st, 1950, in customer deposits held.
Commission policy was revised to exclude most residential consumers from deposit
requirements.
Reserves
The Maintenance and Renewals Reserve has increased by $346,666.32 in the past
year.    Details of this reserve are shown in Statements 5 and 7.
The interest reserve shown at March 31st, 1950, after partially providing for
interest on expropriation balances, was transferred to Contingencies Reserve. The
balance of interest on expropriated values was provided from contingencies where
provision had been made.
Stabilization Reserve
This reserve was increased during the year in the amount of $152,413.16, representing the surplus from operations as detailed in Statements 2, 3, and 4.
STATEMENT 2
This statement shows the financial results of operation for the year ended March
31st, 1951.
STATEMENT 3
This statement also shows the financial results of the year's operation, but utilizes
slightly different groupings of revenue and expenditure items. This statement is directly
related to Statement 4, which shows operating results by individual power districts.
The cost of power delivered to distribution systems shown in total in Statement 3
has been apportioned to power districts on Statement 4 on a monthly maximum kw
demand basis. D 56 " ELECTRIC POWER ACT "
In previous years, this cost was distributed in proportion to the quantity of kilowatt-
hours supplied to each power district. The present method of cost allocation is made
possible by utilization of demand-measuring apparatus in the districts.
GENERAL
The balance of the employer-employee contributory superannuation fund was
$657,692.53 at March 31st, 1951, according to the records of the Superannuation
Commissioner, appointed as administrator of the fund. REPORT OF BRITISH COLUMBIA POWER COMMISSION, 1950-51 D 57
AUDITORS' REPORT
We have examined the balance-sheet of the British Columbia Power Commission
as at March 31, 1951, and the attached statement of combined operations for the year
ended on that date, and have obtained all the information and explanations we have
required. In connection therewith we examined or tested accounting records of the
Commission and other supporting evidence but we did not make a detailed audit of the
transactions.
Proceedings under the terms of the " Electric Power Act" to determine the compensation to be paid for certain properties expropriated were completed during the year
under review. The excess of the compensation awarded over the estimated liability
at March 31, 1950, has been reflected in Plant in Operation and Plant Acquisition
Adjustments.
Full Sinking Fund provision, in accordance with Sections 52 (1) and 53 (10)
of the " Electric Power Act," has been made for the repayment of all general advances
from the Government of the Province of British Columbia and bonds issued by the
Commission,
Effective April 1, 1950, the method of allocating the cost of power to power districts
on the basis of the number of kilowatt-hours delivered monthly was changed to the
monthly maximum-demand method.
We report that, in our opinion, the attached balance-sheet and related statement of
combined operations have been drawn up so as to exhibit a true and correct view of the
state of the affairs of the British Columbia Power Commission as at March 31, 1951, and
the results of its operations for the year ended on that date, according to the best of
our information and the explanations given to us and as shown by the books of the
Commission.
