The Tuolumne Wind Project (TWP) began commercial operation on May 28, 2009 and added a significant amount of renewable energy to the District’s portfolio, taking it to the 28 percent qualified renewable energy eight years ahead of the Board of Directors adopted goal of 20 percent by 2017.

Located in Klickitat County, Washington along the Columbia River, the site has been recognized as one of the most productive wind resource areas in the Western United States.

The project consists of a total of 62 turbines:

42 Siemens Model SWT 2.3 MW – capable of generating 2.3 megawatts of electricity each
20 REpower MM93 2.0 MW – capable of generation 2 megawatts of electricity each

This makes the total generating capacity of the Tuolumne Wind Project 136.6 MW. That is enough green energy to power approximately 44,000 households each year.

This is the first wind facility owned by TID. It plays an important role in providing clean renewable energy that diversifies and complements our extensive energy portfolio. Currently, TID’s ratepayers enjoy a substantial share of the clean and renewable Don Pedro large hydro project and TID’s Renewable Portfolio Standard (RPS) which includes small hydro, solar, geothermal, and wind.
