The Site C Dam is an early-stage project of BC Hydro for a large-scale earth fill hydroelectric dam on the Peace River near Fort St. John in northeastern British Columbia, Canada. The site is downstream from the existing W.A.C. Bennett and Peace Canyon dams. Designs call for an estimated peak capacity of approximately 1,100 MW, average output of 900 MW, and an annual output of 5,100 GWh of electricity. When completed, Site C will be the first large dam built in BC since 1984 and BC's fourth largest producer of electricity. However, the project has drawn considerable opposition from several quarters due to its planned flooding of agricultural land, lack of support from some First Nations groups and local landowners, high cost of the project vs. projected revenues, uncertainty of future demand and future electricity prices, possible alternatives, and cost to the environment.
Two Treaty 8 First Nations, and local landowners have made legal challenges to the dam, though these were dismissed by the federal Court of Appeal. In addition, over 200 scholars, as well as the Royal Society of Canada, have expressed concerns to the federal Liberal government, citing weakness in the regulatory review process and the environmental assessment for the project. In May 2016 the federal government stated it is "not revisiting projects that have been reviewed and approved". On December 11, 2017, John Horgan, the Premier of British Columbia, announced: "We've come to a conclusion that, although Site C is not the project we would have favoured or would have started, it must be completed," thus guaranteeing the completion of the project.
When completed, Site C will be the third of four major dams on the Peace River that were initially proposed in the mid-twentieth century. The first project was the flagship W. A. C. Bennett Dam 19 kilometres west of Hudson's Hope. The Bennett Dam began operation in 1968 and formed Williston Reservoir, which is 95% larger than the Site C reservoir will become. Construction of the Peace Canyon Dam was completed in 1980 at a point 23 km downstream of the W. A. C. Bennett dam. The third dam,"Site C," was also proposed at the time for a site 83 km downriver of the Peace Canyon dam, or approximately 7 km southwest of Fort St. John. Site C would flood an 83 km length of the Peace River valley, widening the river by up to three times, as well as a 10 km length of the Moberly River valley and 14 km of the Halfway River valley. The fourth proposed dam on the British Columbia segment of the Peace River, Site E, near the BC–Alberta border, was removed from the planning process during hearings in 1982.
After hearings between 1981 and 1983, the British Columbia Utilities Commission turned down the Site C project. The commission was critical of BC Hydro's forecasting methods, declaring that it neither explicitly took energy prices into account nor relied on statistically significant past patterns of behaviour. BC Hydro then chose to purchase electricity under long-term contracts from independent power producers, and it continues to do so today. As of 2017 these annual purchases are about four times the capacity of Site C. Once the initial contracts with BC Hydro expire, these independent producers may be free to export their electricity.
In April 2010, passage of the Clean Energy Act exempted the project from further BC Utilities Commission review. Site C was being reconsidered by BC Hydro for two years prior as the utility reconsidered expansion of its dam capacity on the Peace. Also in April 2010, the provincial government announced it would move forward on planning for the project, moving it to the regulatory review phase. The review was mandated under the Canadian Environmental Assessment Act, 2012 (CEAA 2012) and the British Columbia Environmental Assessment Act (BCEAA). To avoid duplication, the governments of Canada and British Columbia set up a cooperative federal-provincial environmental assessment, including a joint review panel (JRP) process.
In October 2014, Site C received environmental assessment approvals from the federal and provincial governments after a three-year environmental review, including a federal/provincial Joint Review Panel process. In December 2014, the provincial government announced a final investment decision, approving the construction of the hydroelectric project at a cost of $8.335 billion, as well as a project reserve of $440 million. A notice of Site C construction commencing in 2015 was issued in July 2015. By March 2016, site clearing, attempts at bank stabilization and the search for bedrock took the majority of BC Hydro's focus - there were no "works" in the ground; the diversion tunnels had not yet been started. BC Premier Christy Clark's stated intention was to get dam construction “to the point of no return” by the time of a scheduled general election in May 2017. The provincial election resulted in the previous Liberal government being defeated and a New Democratic government taking office. The newly elected government requested the BC Utilities Commission 2017 review.
The project has sparked controversy for a number of reasons: First Nations treaty rights are at issue, the dam is thought by many to be economically unviable, and there are concerns about the loss of agriculturally productive land and the overall environmental impact. The federal/provincial Joint Review Panel found that the need for the electricity had not been clearly demonstrated, nor were alternatives to the project evaluated.
A cost estimate produced during the 2007 feasibility study placed the financial cost at a maximum of C$6.6 billion based on the 1981 design, safety, and engineering standards. An updated cost projection was released in May 2011 placing the estimated cost at $7.9 billion, which was revised to $8.3 billion in 2014. This does not include the cost of a transmission line to major population centres, estimated to be in the range of $743 million additional, bringing the total estimated cost to approximately $9 billion. At the invitation of the British Columbia Utilities Commission, Deloitte published a report on the project, and noted that it's likely to miss a crucial river diversion deadline; this will bring the cost to just under $10 billion. Some experts have stated that the costs may reach as high as $11 to 12 billion.
Economic estimates in 2016 by Harry Swain, former chair of the Joint Review Panel and former BC deputy minister of Industry, projected that if all the power were sold to the US spot market, as little as $1.8 billion would be returned, and the rest ($7 billion) of the cost would be covered by taxpayers. Power consumption has not been increasing despite increasing population. Swain also stated that power roughly equivalent to that produced by Site C could be reclaimed from American producers under the Columbia River Treaty at no capital cost to the province; the power is currently sold to American utilities at about half the projected cost of Site C power. British Columbia Utilities Commission has stated that the Canadian entitlement under the treaty, however, is not a suitable source of dependable capacity.
Site C is planned to have 132.5MW of capacity per $billion. In BC Hydro's latest upgrades, the John Hart Dam is planned for 120.2MW of capacity per $billion and the Ruskin Dam is planned for 142.5MW of capacity per $billion.
Members of the Treaty 8 First Nations boycotted the official Site C announcement ceremony at the Bennett Dam in April 2010, and the West Moberly First Nation publicly stated that it was considering legal action to oppose the dam. In April, 2016, a group of landowners and farmers from BC's Peace River Valley launched a legal challenge to the project. The landowners' case states that the Provincial government ignored concerns about the project raised by the Joint Review Panel, including its cost, failure to demonstrate the need for the project, and lack of evaluation of alternatives. Also in April 2016, BC Treaty 8 First Nations filed a legal challenge in the Supreme Court of BC. The Peace Valley Landowners’ Association, BC Treaty 8 First Nations, Alberta Treaty 8 First Nations, and Blueberry River First Nation were pursuing actions in federal court.
As of December 2016, five judicial reviews of Site C's environmental approvals have been dismissed. These include two challenges from the Peace Valley Landowner Association in the B.C. Supreme Court and the Federal Court of Appeal, as well as a pair of challenges against the project's federal and provincial environmental approvals from the West Moberly and Prophet River First Nations. On January 23, 2017, the sixth legal challenge was dismissed, involving Treaty 8 First Nations, which was in the federal court.
In May, 2016 a group of over 200 Canadian scholars signed a letter raising serious concerns about the process used to approve the Site C dam. The Royal Society of Canada took the "unusual step" of writing a separate supporting letter to Prime Minister Justin Trudeau. The letter from those "concerned scholars" summarized their concerns: "Our assessment is that this process did not accord with the commitments of both the provincial and federal governments to reconciliation with and legal obligations to First Nations, protection of the environment, and evidence-based decision-making with scientific integrity." Scientists argue that the environment impacts of the dam and the lack of First Nations consent make the dam a "'bellwether' of the Trudeau government's commitment to develop resources in a more science-based, sustainable and socially responsible way." The federal government rejected the scholars' call to halt construction. Environment and Climate Change Minister Catherine McKenna's office indicated that the government had no intention to revisit the Site C environmental assessment.
Utilities Commission 2017 review
BC's opposition New Democratic Party promised a review of the project by the BC Utilities Commission (BCUC) should they win the 2017 general election. Hydro critic Adrian Dix called the B.C. Liberal government “reckless” for not having already done the review, as was recommended by the federal-provincial Joint Review Panel led by Harry Swain. On November 1, 2017 the BC Utilities Commission released their second and final report, to determine whether to complete or cancel the Site C project. After reviewing several submissions examining the costs and feasibility of geothermal and wind power in comparison with completing Site C, the BCUC made no recommendation as to which outcome, to terminate or to continue Site C, would result in the higher cost. However, the BCUC stated that Site C will be less expensive if demand for electricity outpaces current projections, and alternative sources of energy will be less expensive if Site C experiences additional cost overruns.
Within a month of the final report, the BCUC clarified that they used lower debt-financing costs than IPPs actually pay. Also, the BCUC did not include $4 billion spent on Site C in the cost of choosing IPPs instead.[disputed ] In addition, the BCUC was questioned on its decision to use a 'low load' forecast, which predicts significantly less electricity demand than BC Hydro's mid-load forecast. Business Vancouver, a prominent pro-Site C publication, quotes an expert as saying, “There’s nowhere on the entire planet that is expecting anything less than tremendous growth in energy consumption".
Agricultural land impacts
Annual flooding has deposited rich sediments along the low bank portions of the Peace River. The creation of the Williston Lake reservoir has improved agricultural use on the former floodplain. Since 1967, the annual spring flood measured at Hudson's Hope has been reduced by two-thirds, along with a reduction in ice jams and ice scouring above the riverbank. The Site C project will result in the largest exclusion of land in the 40-year history of BC's Agricultural Land Reserve (ALR). Of the land to be flooded, there are 2,601 hectares (6,430 acres) of Class 2 ALR land within the project activity zone. Permanent losses are estimated at 541 ha (1,340 acres) of currently cultivated land and 1,183 ha (2,920 acres) of land under grazing licence or lease areas. In all, 2,775 ha (6,860 acres) of land will be removed from the ALR for the project. The Joint Review Panel accepted BC Hydro's assessment that "production from the Peace River bottom lands is small and is certainly not important in the context of B.C." The Panel's assessment of earning potential in the next several decades led them to conclude: "The highest and best use of the Peace River valley would appear to be as a reservoir."
Professional agrologist Wendy Holm, past president of the B.C. Institute of Agrologists, noted that flooding agricultural land in the Peace River valley is a bad idea, because it is "the only large tract of land for future horticultural expansion in the province." She notes that much of B.C.'s produce is imported from California, and growing food locally would increase food security for the province.
According to David Suzuki, flooding valuable farmland to build the dam will undermine Canada's international commitments under the Paris Agreement. Suzuki considers the farmland essential to reduce B.C.'s dependence on imported foods and minimize the carbon fuels needed to transport those foods: "It seems to me crazy to put farmland in the north underwater," Suzuki said. "We live in a food chain now in which food grows on average 3,000 kilometres from where it's consumed. The transport of all that food is dependent on fossil fuels. Food has got to be grown much closer to where it's going to be consumed."
In April 2015, the federal and provincial governments named a Joint Review Panel to hold a public hearing on Site C.
In addition to a long list of recommended changes, their assessment stated: "Despite high initial costs, and some uncertainty about when the power would be needed, the Project would provide a large and long-term increment of firm energy and capacity at a price that would benefit future generations. It would do this in a way that would produce a vastly smaller burden of greenhouse gases than any alternative save nuclear power, which B.C. has prohibited." At the time the report was released, the panel added, "Site C would be the least expensive of the alternatives, and its cost advantages would increase with the passing decades as inflation makes alternatives more costly."
In reference to the Paris climate accord, Site C is predicted to prevent approximately 30 to 70 million tonnes of carbon dioxide from being generated in the atmosphere.
Ottawa has discussed a new electricity inter-tie to move Site C power between BC and Alberta. Justin Trudeau commented “I think anything we can work together inter-provincially or nationally [to get] emissions down, emphasizing hydroelectricity, creating opportunities to get off coal, to get off natural gas, where possible, is good for the country. It’s good for our emissions profile; it’s good for the economy we need to build,” 
Costs to Indigenous Peoples

The land that the Site C dam construction will affect has significance to the Dane-zaa, Cree, Métis and other Indigenous peoples of the region. An environmental assessment done[by whom?] independently concluded[where?] that the project would "severely undermine" the Indigenous peoples ability to carry out cultural and economic practices such as hunting and fishing. Northeastern BC Indigenous peoples have already had their rights undermined by other resource development projects, like the WAC Bennett Dam which is on the same river as Site C. BC Hydro, the public utility which built and operates the Bennett dam, opened a public display at the dam itself that acknowledged the harm done to the Tsay Keh Dene and Kwadacha First Nations. Speaking at the opening of the exhibit, a BC Hydro spokesperson said that the utility "deeply regrets those impacts and we commit that we will not repeat the mistakes of the past". The government failed to give proper consideration to Canada's legal obligation to protect Indigenous rights. It also failed to examine the impact of an influx of temporary workers on the safety of women, especially Indigenous women. The risk of serious harm to the rights of Indigenous peoples requires that large-scale resource development proceed only with their free, prior and informed consent.
First Nations have identified hundreds of sacred sites or areas with cultural or historic significance in the planned Site C flood zone. The Indigenous peoples of the area use the valley to hunt, fish trap, and gather berries as well as conduct ceremonies and harvest wild foods. The valley is prime habitat for moose, which is a food source they rely on, and other animals like the bear and eagle. The dam could also harm an already threatened fish species, the bull trout. The flooding of the valley may poison the fish with methylmercury for 20–30 years. Today,[when?] berry patches are harder to find, springs and streams are dirty and contaminated, and moose have become scarce.
Resource extraction has led to rapid population growth in the region. As a result of road construction and logging, non-Indigenous fisherman and hunters now have access to dwindling harvests. Just over 110 square km is recognized as reserve lands and this is not enough to sustain First Nations cultures and traditions. Indigenous peoples have ongoing rights to harvest foods and practice their customs throughout their broader territory but because of intensive resource development there are fewer and fewer places left where this is possible. The Peace River Valley falls within the bounds of Treaty 8, which recognizes First Nations rights to hunt, trap, and fish throughout the region. Activist Helen Knott has said that if the valley is flooded then the promise of that treaty will be violated.
Indigenous women and girls will face extra harm from this infrastructure project due to the influx of highly paid, temporary workers. Indigenous women and girls are at least 3 times more likely to experience violence than all other women and are 6 times more likely to be murdered. It is likely these stats are lower than reality because of the underreporting by Indigenous communities and failing to accurately record crimes by police when victims are Indigenous. Short-term and temporary workers in resource industry jobs in Peace River Valley generally get paid well above the national average, which attracts workers from all over the country. Most of the high paying jobs go to men and on average, women are actually paid below the national average for women. The large number of high paid workers has driven up local prices including necessities such as housing, childcare and medical services. People who are not part of the resource sector (with high wages) are negatively affected and may not be able to afford suitable accommodations. A combination of low wages for women and a high cost of living create a dangerous dependency on a male partner make it hard for women to escape situations where their safety is at risk. The tens of thousands of men who pass through the region for work include some who are a threat to women and this is increased by the high-stress jobs, potential binge drinking and drug abuse. In 2014 Fort St. John had the highest per capita crime rate and the highest caseload per police officer among 31 BC municipalities.
The assessment of the Site C dam failed to consider specific impacts on Indigenous people.
Electricity conservation is the least-cost alternative. BC Hydro achieved savings at $20/MWh, while the estimated savings were at $30/MWh. Columbia Treaty and non-treaty power now sold to the US, is available at approximately $30/MWh, equivalent to Site C quantities. BC Hydro determined in the 2013 Integrated Resource Plan, DSM 5, that more than double the amount of power from Site C could be obtained from conservation at up to $45/MWh.
In 2017, Alberta received quotations for 600 MW of wind power at $37/MWh.
When BC Hydro buys power from independent power producers they set a price as low as $76.20 per megawatt hour for intermittent power from wind farms, and as high as $133.80 for firm hydro power. The average price paid, as of 2010, was $100 per megawatt hour. Site C is expected to cost $83 per megawatt hour for firm hydro power.
BC has committed to reducing greenhouse gases to 33 per cent below 2007 levels by 2020; however, the province is far short of that goal, only achieving a 6.5% reduction as of 2015. Although the Site C dam is expected to have a large initial electricity surplus, the province has proposed to sell this power rather than choosing to reduce fossil fuel consumption in BC.
