Regulators in New Jersey awarded the rights on Friday for construction of a $1 billion offshore wind farm in the southern part of the state to Garden State Offshore Energy. The rights, which include access to as much as $19 million in state grants, is part of New Jersey’s Energy Master Plan, which calls for 20 percent of the state’s energy to come from renewable sources by 2020. The decision comes on the heels of decisions by Delaware and Rhode Island to allow the installation of offshore wind farms.

Energy experts say that these approvals could prompt regulators in New York to support projects off the south shore of Long Island and New York City.

Garden State Offshore Energy is a joint venture that includes P.S.E.G. Renewable Generation, a subsidiary of P.S.E.G. Global, which is a sister company of the state’s largest utility, Public Service Electric and Gas Company.

The proposal by Garden State Offshore Energy includes the installation of 96 turbines to produce as much as 346 megawatts of electricity, enough to power tens of thousands of houses, starting in 2013. The turbines would be arranged in a rectangle about a half-mile long by one-third of a mile wide and would be placed 16 to 20 miles off the coast of New Jersey’s Atlantic and Ocean Counties, much farther out and in much deeper water than other proposed wind farms. Deepwater Wind, which will work with P.S.E.G. to build the wind farm, said it could affordably build turbines in 100 feet of water with the same technology used to build oil and gas rigs in the Gulf of Mexico and other places.
