NEW YORK, NY — KeySpan Corp. believes natural gas is an answer to Long Island's 36-year search for energy and is participating in four pipeline projects that will deliver nearly 1 billion cubic ft of gas daily to New York City's eastern suburbs.

Completion of all four pipelines will increase KeySpan's capacity to deliver natural gas on Long Island by roughly 50%, filling the gas mains the utility is building at the rate of 200 miles (322 km) per year and providing fuel for 500 MW of new generation proposed for construction over the next few years.
