Public Service Electric & Gas Co. proposed $888 million in accelerated capital projects to boost the New Jersey economy over the next two years, the Newark utility said. Filings with the New Jersey Board of Public Utilities included $406 million in electric system capital improvements, $292 million in gas system investments, and $190 million in additional money for energy efficiency projects. South Jersey Gas, a subsidiary of South Jersey Industries Inc. in Folsom, said previously that it planned to expedite $100 million in infrastructure projects. Both companies responded to Gov. Corzine's request in October that utilities do what they can to invigorate the economy.
