According to an article published this past Monday by Newsday, National Grid has sold the "Big Allis" Ravenswood Keyspan Plant located just opoposite Roosevelt Island, in LIC, Queens, to Trans-Canada. The sale is subject to state and federal regulatory approvals, and clearance under U.S. anti-trust and foreign investment laws. National Grid said it expects to complete the deal by late summer.
