“I think it’s across the board,” said Joseph Fitzpatrick, president and chief executive of DG Clean Power.
The company recently won a permit from the state for the Billerica plant, but plans to delay construction for one or two years, Fitzpatrick said. The company also wonÂ’t begin seeking approvals for the Uxbridge project until at least a year from now.
The reason: demand for power is dropping due to the recession and conservation efforts, he said. New power plants canÂ’t get financing under such circumstances, Fitzpatrick said.
“Clearly, it’s going to impact the in-service date of some of these plants,” he said.
Power consumption fell by 1.9 percent last year in New England, said Marcia Blomberg, a spokeswoman for electricity overseer ISO New England.
The organizationÂ’s forecasts are also dropping. Power consumption will be 4 percent lower this year and 5 percent lower next year than had been previously forecast in a 2008 report, Blomberg said.
Most current power plant projects — including the 350-megawatt Brockton plant, first proposed in 2007 — were drawn up at a time when electricity forecasts were going up, not down.
Still, the company behind the Brockton plant contends the project will move forward on schedule. The plant is slated to open in 2011.
“The project is on firm footing,” said Wesley Eberle, a spokesman for Advanced Power.
Eberle said the company believes power demand will eventually rise, and the company is taking a long-term view.
He also said the project will not have trouble finding financing due to project partners such as Siemens Financial Services.
The project is awaiting a final approval from the state Energy Facilities Siting Board to move forward.
The board, which granted its approval to the Billerica plant, has not yet scheduled a vote on the Brockton project.
The project also needs numerous local approvals, including at least one zoning variance, for which the company has not yet applied, said Drew Hoyt, a Plymouth lawyer who has represented the city of Brockton in the legal case of the project.
The plant would burn natural gas and diesel fuel and be built off Oak Hill Way on the cityÂ’s south side.
The project has faced opposition from Brockton officials and residents amid concerns over possible health impacts and the location of the plant near homes, schools and large numbers of low-income and minority residents.
