The DOE is investing up to $1.18 million for a project in Boulder, Colo. to upgrade the 100-year-old Boulder Canyon Hydroelectric Project by replacing two older turbines with a single unit. The new turbine is expected to operate at a wider range of flows and higher efficiency ranges, resulting in an increase in annual generation of 11,000 MWh (30% increase).
Along with 6 other projects the DOE is investing $30.6 million to create an additional 187,000 MWh/year, while replacing turbines that are as much as 90 and 100 years old. Clean (cutting 110,00o tons of CO2 emissions/year), cheap (adding generation at less than 4 cents per kWh) and lowering operating and maintenance costs.
