MASS SOLAR

TransAlta’s first solar project, Mass Solar in Massachusetts, United States, can generate 21 megawatts (MW) of renewable energy. Acquired in 2015, the project aligns with our strategy of growing our renewables platform and diversifying our portfolio. The expansion into new geographic markets and technologies further enhances our position as a leader in renewable energy and provides potential for future opportunities in the U.S.

Mass Solar Projects

Mass Solar, consists of four ground-mounted projects and four roof-top projects in Massachusetts, United States. These projects consist of just over 73,000 solar panels, two meters long and one meter wide, weighing around 60 pounds each. With the capacity to generate 21 megawatts (MW) of renewable energy, Mass Solar is the next step in growing our renewables portfolio and diversifying our presence in the U.S.

Lakeswind

Lakeswind wind facility is located approximately 35 miles southwest of Fargo, North Dakota, in Rollag, Minnesota. This is TransAlta’s second wind project in the United States, with the capacity to generate 50 megawatts (MW). The fully operational facility was acquired from Rockland Capital in September 2015, with fully contracted customers holding long term contracts.

This acquisition supports the overall strategy of growing TransAlta’s renewables platform and diversifying our presence in the US. It also allows us, as Canada’s largest wind operator, to bring our expertise and experience to the US.

Located on a 10,318 acre site in Rollag, Minnesota and consists of 32 GE 1.5 megawatt (MW) turbines with a rotor diameter of 82.5 meters.

Wyoming

Wyoming Wind represents TransAlta’s first wind project in the United States. The fully operational facility was acquired from NextEra Energy Resources in 2013. While NextEra Energy will continue to operate the facility, it is 100% owned by TransAlta Renewables.

This acquisition supports the overall strategy of growing TransAlta’s renewables platform and diversifying our presence in the US. It also allows us, as Canada’s largest wind operator, to bring our expertise and experience to the US.

Located within the Rocky Mountains, the Wyoming facility is in south-western Wyoming, approximately 15km east-northeast of Evanston and commenced commercial operation in December, 2003.

Centralia

Centralia Coal Plant is Washington State’s largest baseload power source; the reliable and steady supply of power from our operations is essential for keeping the west-coast electrical grid stable. Centralia Coal Plant has a net capacity of 1,340 megawatts.

The facility is a merchant plant, which means that costs such as environmental upgrades cannot be passed on to customers. TransAlta has invested more than US$300 million in pollution control technology at Centralia Plant, including scrubbers and low nitrogen dioxide burners. Today, the facility is one of the cleanest coal-fired power plants in North America.

Fuel for Centralia Plant is delivered by train from the Powder River Basin in the U.S. Midwest. The plant’s coal unloading facility is considered one of the most efficient and environmentally friendly in North America.

Skookumchuck

The Skookumchuck Dam is located in Thurston County, in Washington State, approximately 10 miles or 16 kilometers upstream from Centralia. Skookumchuck is a run-of-river dam constructed in 1970 to support our operations. A four-mile long reservoir provides water to our Centralia Coal Plant and Centralia Gas.

Skookumchuck is an earthfill structure approximately 190 feet (58 metres) high and 1,340 feet (408 metres) long. In 1990, a small powerhouse was constructed to produce hydro power from the site.

The dam has a multi-level intake system located at elevations of 449 (137 metres), 420 (128 metres) and 378 feet (115 metres) that allows water temperature below the dam to be maintained at less than 60 degrees Fahrenheit (15 degrees Celsius). The Washington Department of Fish and Wildlife (WDFW) uses a portion of the water for a fish-rearing facility downstream of the dam.
