PSEG Long Island Completes Successful Upgrade of its Outage Management System

New OMS upgrade provides technology for a more reliable, efficient storm response

(UNIONDALE, N.Y. – Feb. 10, 2022) – Throughout 2021, PSEG Long Island incorporated numerous enhancements and upgrades to the electric grid, its systems and storm processes, including business and technology contingency plans and procedures.

A key focus area has been an upgrade to the PSEG Long Island outage management system (OMS), which was put into production over the weekend of February 5. The upgrade to OMS version 6.7.8, improves the quality of the reporting data, and the dispatching and scheduling of work. It will help provide a more reliable and efficient storm response.

“PSEG Long Island has successfully completed multiple tests and readiness reviews to ensure the Outage Management System version 6.7.8 is able to handle severe storm conditions and can be trusted by both PSEG Long Island and Long Island customers,” said Greg Filipkowski, managing director and CIO at PSEG Long Island.

Leading up to this upgrade, PSEG Long Island and its vendors have completed extensive regression and performance stress testing to ensure the new Outage Management System is able to pass PSEG Long Island’s stringent validation criteria. PSEG Long Island successfully completed two separate performance stress tests that simulated call volumes experienced during Tropical Storm Isaias and call volumes that would simulate an outage impacting 90% of PSEG Long Island’s customers.

The upgrade to OMS version 6.7.8 replaces an earlier version of OMS, version 5.5, which included many enhancements that addressed the issues that occurred during Tropical Storm Isaias.
