  • Oct. 2006: The electric transmission system that supplies Ithaca and

the surrounding area is currently dependent on nearby power generation resources to be available and operating to ensure reliable service. Ordering Clause 9 of the PSC's order in Case 05-E- 1222 issued on August 23, 2006, requires NYSEG to submit all government and regulatory filings necessary to reinforce transmission infrastructure in the Ithaca area. To comply with the ordering clause, NYSEG is proposing the Ithaca Transmission Project to eliminate the transmission limitations in the Ithaca area and maintain adequate normal and contingency service throughout NYSEG's Ithaca Division during extended

  • utages (forced or planned) of the AES-owned Cayuga Station

generating units.

NOW IN SERVICE, NYSEG’s ITHACA TRANSMISSION PROJECT WILL ENHANCE RELIABILITY ACROSS THE REGION FOR IMMEDIATE RELEASE

Ithaca, NY, August 26, 2010 NYSEG’s Ithaca Transmission Project, which eliminates the reliance on local generation to ensure reliable service in the region, is now in service after approximately a year of site and construction work.

Begun in 2010, with inclusive, collaborative efforts of neighboring electric grid operators, the NYISO’s Broader Regional Markets initiatives seek to mend differences, or “seams,” in interconnected grids; enhancing the efficiency of existing resources and reducing costs for power consumers. Among the improvements achieved through collaborative analyses and planning with other grids have been more efficient interregional scheduling practices and power flows, and more cost-effective solutions for transmission system constraints. The combined initiatives are projected to save New York $193 million a year and save the region $362 million annually.
