HARTFORD - NRG Energy Inc., backed by organized labor and Montville officials, is seeking a requirement by Connecticut that Northeast Utilities agree to buy power from an alternative energy plant as a condition of the utility’s purchase of Boston-based NStar.
The demand mirrors an agreement in Massachusetts. Hartford-based Northeast Utilities and NStar agreed to buy more than a quarter of the power produced by the Cape Wind offshore wind farm as a condition of the deal.
NRG said its Montville biomass project would provide up to 40 megawatts of power from wood chips, enough for about 32,000 homes. The company will not build it without a power purchase agreement.
The project also is being promoted as helping meet Connecticut’s goal of having 20 percent of power from renewable resources by 2020.
A spokesman for Northeast Utilities said the project has no connection to the NStar deal, but NU expects Connecticut’s decision will reflect “consideration of all comments.’’
