WOODBURY - New details have been released regarding LIPA's plan to build a new power plant in Yaphank.

As Newsday reports, the 752-megawatt Caithness II plant would require substantial upgrades to the electric grid, which could cost hundreds of millions of dollars and result in older plants being used less.

LIPA, PSEG and state regulators are still studying the needed upgrades and their associated costs.

A final decision on the $3 billion project is expected to be reached by the end of this year.
