ITC seeks permit from Canadian National Energy Board for 1000MW Lake Erie Connector project


ITC Lake Erie Connector, subsidiary of US power transmission firm ITC Holdings, has filed a permit application with National Energy Board (NEB) of Canada for its 1000MW ITC Lake Erie Connector transmission line.

The proposed connector will be a +/- 320 kV bi-directional, high-voltage direct current (HVDC) merchant transmission line.

It will be the first direct link connecting the markets of the Ontario Independent Electricity System Operator (IESO) and PJM Interconnection.

Once operational, the line will facilitate power transmission for customers, and open up access for energy, capacity, and renewable energy credit opportunities, in both markets.

"The proposed connector will be a +/- 320 kV bi-directional, high-voltage direct current (HVDC) merchant transmission line."

ITC Holdings International and Merchant Development vice-president Terry Harvill said: "The bi-directional design of this transmission line means that electricity can flow into Ontario from a new route, helping improve the security and reliability of the power grid, and the line also could potentially play a role in emergency grid restoration in the province.

"The Lake Erie Connector would also provide Ontario with access to a new market to export its excess supply of energy."

The connector will stretch for 73 miles and will interconnect converter stations located in Erie, Pennsylvania and Nanticoke, Ontario.

One 345kV alternating current (AC) underground transmission line will join the converter station at Erie to the existing Penelec ErieWest Substation. Another 500 kV AC line will interconnect the Nanticoke converter station to Hydro One Networks-owned Nanticoke Transformer Station.

Most of the connector will be buried beneath Lake Erie or be underground, ITC said.

The firm expects to obtain all state, federal, and provincial permits for the ITC Lake ErieConnector by the second quarter of 2017.

Construction for the transmission link is likely to start in 2017, and it is expected to be operational in 2019.
