Recently, the cost of the power line nearly doubled to $272 million. Delaware Public Advocate David Bonar says Delaware's ratepayers will be paying 99 percent of the cost for New Jersey's ratepayers.
The power line connects Artificial Island to Delaware, and is expected to improve reliability and increase the plant's power output.
Initially, PJM, the company overseeing the project, estimated the transmission line would cost $137 million. That price doubled last month.
Bonar and other state officials are outraged over the project's cost increases and proposed tax increases. Jonathan Dworkin, spokesman for Governor Jack Markell, says the governor has reached out to PJM to share his concerns.
