RUN-OF-RIVER DEVELOPMENTS

N 9 September 2009, the community of Atlin, British

Columbia, Canada, gathered to celebrate the ofﬁcial

grand opening of the Atlin hydroelectric project. The

community as a whole, and the Taku River Tlingit First

Nation (TRTFN) in particular, had much to celebrate. The 2.1MW

Atlin project had been commissioned and operating smoothly for

more than ﬁve months.

Until recently, the community of Atlin’s electricity was provided

using diesel generators. These necessitated the delivery of more than

1M litres of diesel fuel per year to the 400 residents of Atlin, which is

located in the far northwest of British Columbia. The pollution associ-

ated with this was becoming a cause for concern and, consequently,

hydro power became a focal point in the community.

PROJECT CONCEPT

The directors of the Taku Land Corporation (TLC), a company wholly

owned by the TRTFN, envisioned a project that would embody the

fundamental principles presented in the TRTFN Constitution. The

project would prevent the air pollution created by the diesel gen-

erators, thereby protecting the TRTFN traditional territory. Project

revenues would remain in the community, strengthening the local

economy and creating employment and contracting opportunities for

TRTFN members and local residents.

In 2003, the Atlin Tlingit Development Corporation (ATDC) began

work with BC Hydro, the provincial power utility, to develop a com-

munity energy plan, which led to TLC submitting an expression of

interest to BC Hydro in July 2005. This EOI in turn, led to the signing

of a 25-year power purchase agreement in November 2006.

TLC engaged Sigma Engineering of Vancouver to provide techni-

cal expertise for the development of the project. Sigma already had

experience of working in the Atlin area. In a 1990 BC Hydro request

for proposals, Sigma and its sister company Synex Energy Resources

prepared a successful proposal to develop a 7.1MW project on Pine

Creek. This project would have supplied electricity to Atlin with the

surplus energy being sold to the Yukon Territory (north of British

Columbia); however, it was deferred when the energy needs of the

Yukon Territory declined.

The Atlin project conceptualised by TLC and Sigma was a low

impact 2.1MW modiﬁed run-of-river plant (see ﬁgure 1). The scheme

RUN-OF-RIVER DEVELOPMENTS

includes a low control structure at the outlet of Surprise Lake, hence

the modiﬁed run-of-river operation. This control structure creates

additional storage on the lake and allows project operators to control

the ﬂow being released into Pine Creek. Since the project displaces

diesel generation on a non-integrated grid, the project’s capacity

factor is extremely important, and the use of Surprise Lake storage

is a key factor.

The project also includes an intake and weir that divert water into

the penstock and to the powerhouse. The powerhouse includes an

outdoor switchyard and a 25kV powerline that connects the project

to the local Atlin grid.

WATER POWER POTENTIAL

The mean annual ﬂow at the project intake was estimated at 4.2m

sec. This estimate was calculated from a 36-year long streamﬂow

record that Sigma synthesised based on two gauges: one on Pine

Creek and the other on the nearby Gladys River.

Pine Creek is a snowmelt driven system with very low precipitation;

an average of 347mm of precipitation falls annually (1971-2000).

High ﬂows occur in June as the result of snowmelt. Since the period

of low ﬂows coincides with the period of high electricity demand,

storage was required on Surprise Lake to displace diesel generation

year-round. Surprise Lake levels were modelled based on Pine Creek

outﬂow over the period of record to determine the amount of storage

required. The model showed that 1.1m of storage would be required

on Surprise Lake to meet the community of Atlin’s projected electric-

ity needs 20 years in the future. Atlin’s current electricity demand

is approximately 4.67GWh annually; this demand is projected to

increase to 6.98GWh in 2034.

PROJECT PERMITTING

Environmental studies for the project began in 2004. These addressed

the full range of possible impacts: ﬁsh and ﬁsh habitat, wildlife and

archaeology. The project team also assessed potential effects on

TRTFN traditional use of the land, cultural resources, recreation

and public safety.

Prior to construction commencing, TLC project manager, Stuart

Simpson, worked with provincial and federal agencies to ensure that

all required permits and authorisations were in place. Before a water

licence and crown land tenure were issued, TLC submitted a devel-

opment plan to the appropriate ministries describing the project, its

potential effects, and the mitigation measures that would be under-

taken to minimise these.

The project triggered an environmental assessment under the

Canadian Environmental Assessment Act based on three factors: there

are arctic grayling in the control structure area, Pine Creek is a navigable

water body, and federal funding was received. A provincial environmen-

tal assessment was not triggered since the project is smaller than the BC

Environmental Assessment Ofﬁce’s 50MW threshold.

A number of characteristics contributed to making it particularly

environmentally beneﬁcial and socially responsible. These are:

U The project replaces diesel generation and is expected to prevent the

emission of over 100,000 tonnes of greenhouse gasses (CO

and

) over the next 25 years.

U It is locally owned by the TRTFN; all revenue will be reinvested

into the local economy creating local employment and contract-

ing opportunities.

U The Atlin region has a long history of placer mining. The settle-

ment of Discovery, home to approximately 10,000 people during

the 1898 gold rush, was located on Pine Creek. The project is

located in areas that were previously impacted by placer mining.

There was even a small hydro project in operation during the

gold rush days.

U Fish access to the upper portion of Pine Creek is restricted by a

set of falls. Arctic grayling (Thymallus arcticus) and slimy sculpin

(Cottus cognatus) are present in the control structure area, but no

ﬁsh were caught in the intake area.

In situations where foreseeing the magnitude of environmental

impact was difﬁcult, an adaptive management plan was implemented

to ensure that these effects are mitigated. For example, ﬂuctuating

Surprise Lake levels could have a negative impact on nesting shore-

birds and waterfowl. In response to this concern, a set of interim

lake level guidelines was drafted. Nesting habitats will be monitored

during critical nesting periods for shorebirds, and the lake level guide-

lines will be adjusted as appropriate.

PROJECT FUNDING

The project was funded through a combination of grants, equity

ﬁnancing and debt ﬁnancing. The cost was higher than would usu-

ally be expected for a project of its size due to its remote location and

the moderate penstock gradient (average slope 2.7%). However, it is

ﬁnancially viable because it replaces diesel generation and, therefore,

receives a higher electricity purchase price than projects connected to

the main British Columbia grid.

The project, particularly during the development stage, received

grants from a number of government sources aimed at reducing cli-

mate change:

U Indian and Northern Affairs Canada.

U Aboriginal and Northern Communities Action Programme.

U British Columbia Ministry of Energy Mines & Petroleum Resources.

Equity ﬁnancing was provided by other TRTFN corporations and

EcoTrust Capital Canada. The majority of the project’s construc-

tion was funded through debt ﬁnancing provided by the Canada Life

Insurance Company of Canada.

DESIGN AND CONSTRUCTION

Sigma was the prime engineering consultant for the design and con-

struction. The sub-consultants were Schneider Canada of Victoria, BC

(electrical engineering), Sargent and Associates of Victoria, BC (struc-

tural engineering), and EBA of Whitehorse, Yukon Territory (geotech-

nical engineering). BC Hydro conducted the interconnection work.

Construction was completed in two stages. The control struc-

ture was designed ﬁrst and built in the spring of 2007 by Johnston

Construction of Galloway, BC. The remainder was built between

May 2008 and March 2009 by Arctic Construction of Fort St. John,

BC (general contractor). This construction sequence allowed the

additional storage at the control structure to ﬁll during the spring

freshet before being required for project operation.

Atlin is located in a very cold and relatively remote area of British

Columbia. Both of these factors provided additional challenges for

the team. When possible, TLC engaged local people and businesses

Beginning of powerhouse building erection

RUN-OF-RIVER DEVELOPMENTS

to provide materials and services. Hiring locally helped to keep costs

down and was consistent with the TLC’s goals for the project. There

were approximately 200 individuals and 35 companies involved and

of these, approximately 10 were from the Atlin area and 20 were

northern companies.

A brief summary of each of the project components is included in

the sections below (also see Table 1).

Control structure

The control structure includes a sheet pile and rip-rap weir built at the

outlet of Surprise Lake. The weir is at an existing road bridge and ties

into the road embankments. To lengthen the seepage path under the

weir, a 45mm EPDM membrane sandwiched between two layers of

non-woven geotextile was extended 10m upstream of the weir. The

membrane and geotextile layers were protected by a layer of drain

rock. A geotextile ﬁlter was extended 7m downstream of the weir and

protected using a layer of pea gravel and a layer of rip rap.

A 1.8m diameter culvert through the left road embankment releases

ﬂow from Surprise Lake into Pine Creek. An oriﬁce-type ﬁshway also

passes through the left road embankment. This ﬁshway has improved

arctic grayling migration between Pine Creek and Surprise Lake.

The timing of control structure construction was extremely impor-

tant. Construction occurred during the spring low ﬂow period and

needed to be completed before the start of the freshet. This construc-

tion window meant that crews had to begin work when temperatures

were still well below freezing. Excavation of the frozen road embank-

ment was extremely difﬁcult, and concrete had to be covered and

heated following pours.

Intake

The Atlin intake consists of a small concrete gravity dam and a rein-

forced concrete intake that is located approximately 25m upstream of

the dam. The concrete gravity dam has a maximum height of 9.25m

from its bedrock base. During typical ﬂows water not required by

the project ﬂows over the 14m wide ogee-type spillway. During ﬂood

ﬂows, water also ﬂows over the 14.4m wide secondary spillway.

The intake structure includes a penstock slide gate as well as coarse

and ﬁne trashracks. Water ﬂows from the intake into a short sec-

tion of 1.52m diameter steel pipe. This portion of the penstock was

designed to allow the reducer to be exchanged for a bifurcation if the

plant is expanded in the future.

Atlin’s cold climate was considered in the design of the intake and

weir, including winter operation and the impacts of ice. The weir is

higher than for comparable projects because the required submer-

gence over the penstock inlet includes a 0.5m thick ice allowance.

Non-metallic trashracks were used at the project intake to reduce the

tendency of frazil ice to stick to these structures. The coarse trashrack

can be removed during the winter months to prevent it from being

damaged by ice. The ﬁne trashrack is submerged and therefore less

susceptible to ice damage.

Penstock

The buried penstock is 3910m long and made of 1.22m HDPE and

steel pipe. The minimum depth of ﬁll over the penstock is 1.35m;

this burial depth ensures that water in the penstock does not freeze.

Burying the penstock also guarantees that wildlife migration across

the penstock route is unimpeded.

Powerhouse

The powerhouse is a prefabricated steel building on a concrete foun-

dation. The building houses the generating equipment, crane and con-

trols. The switchyard is located adjacent to the powerhouse.

Generating equipment

The generating equipment consists of 2x1MW horizontal axis Pelton

wheels, double overhung on a single generator. The turbine and gen-

erator were supplied by the Chongqing Yunhe Industry (Group) Co

of Chongqing, China.

Since the community of Atlin is not connected to the provincial

electricity grid, the controls for the turbine and generator needed to

be different from conventional run-of-river projects. Rather than con-

stantly adjusting to meet the community’s electricity needs, the project

generates electricity at a constant rate greater than the demand. A

load bank is used to disperse the excess energy.

RUN-OF-RIVER DEVELOPMENTS

Powerline

A 750m long, 25kV powerline and 3.15km of 25kV express feeder con-

nect the project to the diesel generating station and the local Atlin grid.

Project operations

For long-term operations, TLC transferred ownership of the

project to the Xeitl Limited Partnership (XLP), which is also

wholly owned by the TRTFN. (Xeitl is the Tlingit word for light-

ning, which is the closest Tlingit word relating to electricity.) The

project is one of the ﬁrst small hydroelectric projects in Canada to

be wholly owned and operated by a First Nation.

The project generated 1.95GWh of electricity over its ﬁrst six months

of operation. Stuart Simpson, now operations manager, reports that

the plant is running nearly ﬂawlessly. There have been eight outages

since project commissioning, but none of these have been caused by

project breakdowns. The outages have been caused by a combination

of operator error during training, trees falling on the powerline and

ravens landing on neighbourhood transformers.

Simpson also reports that the XLP has been very impressed with

the facilities.

SUCCESS STORY

The Atlin hydro project has been extremely successful from a number of

aspects. The plant has been operating smoothly since commissioning, and

it will meet Atlin’s electricity needs for many years to come. Although the

current project conﬁguration has been sized to provide Atlin with elec-

tricity for the next 25 years, it has also been built to be expandable if the

area’s energy demands increase faster than forecasted.

The project’s success is largely due to the resolve of TLC, XLP and

the people who have spent the past ﬁve years advancing the work,

including Peter Kirby (president) and Stuart Simpson (project man-

ager). Good teamwork and effective communication, despite large

geographic separations, were also paramount.

The project is a perfect example of how water power can be envi-

ronmentally beneﬁcial and socially responsible. The XLP team is now

frequently solicited to speak at conferences as well as to provide advice

to other First Nations in western Canada about building their own

small hydro projects. It demonstrates what can be accomplished when

people strive to reach a common goal.
