Tax credits are currently available for wind energy projects (onshore or offshore) that begin operating before the end of 2012.
But the senators say that offshore developers need the extended credit because their projects have longer lead times for permits and construction.
“Guaranteeing these tax incentives through 2020 will provide companies with the certainty they need to plan for the long term and encourage further development even in these challenging economic times,” Carper said in a prepared statement.
The company NRG Bluewater Wind plans to build a wind farm off Delaware’s coast that the company claims will provide enough energy for up to 100,000 households.
The four lawmakers will face a challenge gaining traction for their bill – Congress has typically extended renewable energy tax credits in far shorter increments than the extension they’re seeking.
