Connecticut Struggles to Proceed with Transmission Upgrade
LCG, August 18, 2004--ISO New England, Connecticut Light & Power and United Illuminating Company jointly filed a report earlier this week with the Connecticut Siting Council for a proposed Middletown-Norwalk transmission upgrade that is part of a multi-phase plan to upgrade the state's power grid. "Of the dozen alternatives we studied, only one appears to be marginally acceptable in resolving some of the technical reliability issues," says Steve Whitley, ISO New England's Chief Operating Officer.The proposal includes the last 24 miles of the Middletown-Norwalk line run underground into Norwalk. ISO New England is concerned with the complexity and use of static synchronous compensators (STATCOMs) rather than capacitors. "Undergrounding 24 miles of transmission lines and the extensive use of this technology is unprecedented - particularly when it is connected to an area as weak as Southwest Connecticut's system," said Whitley. Additional studies to determine if ISO New England can support the project are expected to be completed by the end of September.Another issue is who pays the additional costs - estimated to be at least $250 million - for underground rather than above ground cables. In the filing, ISO New England cautions that the increased costs are unlikely to qualify for regional cost support and that Connecticut residents and businesses may be responsible for such costs. The City of Norwalk and its residents desire the underground design. Who pays and how quickly the upgrade design is approved, installed and allowed to commence operations is difficult to project, especially when one considers Connecticut's track record with the Cross Sound Cable.
