Last week the Portland Press Herald reported that the Maine Public Utilities Commission will direct Maine’s transmission and distribution utilities to enter into a long-term contract with Dirigo Solar for the construction of up to 75 MW of new solar installations across the state.
The Commission was especially pleased with the price offered by Dirigo. According to a term sheet filed with the Commission last month, the price will be $35/MWh for all of the energy and capacity benefits generated by the solar projects. The price will increase by 2.5% annually over a total term of 20 years. These terms compare very favorably with other long-term renewable contracts approved by the Commission.
Earlier this year, for example, the Commission approved a 25-year contract for the Highland Wind project at a price of $43.80/MWh with the same annual 2.5% increase. Although the Highland Wind contract included other provisions that make an apples-to-apples comparison difficult, $35/MWh is nevertheless an impressive price for solar.
