The award of offshore wind contracts with state utility companies has been delayed until May 23, according to a statement from the Massachusetts office of Energy and Environmental Affairs this week.

Up to two contracts were expected to be announced Monday.

Three developers with leases to construct a utility-scale wind farms about 15 miles south of the Vineyard are in the running for contracts: Vineyard Wind, Baystate Wind and Deepwater Wind.

The delay is due to an unrelated hydropower project still under review and the spate of winter storms that forced the cancellation of a number of meetings, a state EEA spokesman said.
