LS Power Grid | Grid NY Project Logo

In 2019, LS Power Grid New York, together with the New York Power Authority, was designated by the NYISO through a competitive solicitation to construct, own, and operate the Central East Energy Connect project.

Designed to address bottlenecks that limit the flow of electric power across New York state, LS Power Grid New York’s innovative solutions greatly enhance the capacity of existing lines. Approximately 93 miles in length, the Central East Energy Connect project has a number of different components, each designed to provide an efficient, low-cost solution.

Along most of its length, LS Power Grid New York replaced two sets of aging “H”-frame transmission towers with just one set of modern monopole structures that can move more electricity, more efficiently – the new infrastructure installed along that segment can carry approximately five times the capacity of the lines they replaced. The project also included upgrades at several existing substations and the construction of two new, indoor gas-insulated substations using state-of-the-art technology. By using existing rights-of-way and today’s best technologies, LS Power Grid New York helped minimize the impact on residents and communities.

Silver Run Expansion Project

In 2023, Silver Run Electric was selected by PJM through a competitive solicitation process to construct, own, and operate, the Silver Run Expansion Project. The existing submarine cables under the Delaware River will become overloaded under certain system conditions resulting from adding future offshore wind energy in New Jersey on the regional electric grid.

The Silver Run Expansion Project addresses these issues by adding additional submarine cables to the existing transmission path between the Silver Run substation in Delaware and the Hope Creek substation in New Jersey. These new cables will increase the capacity of the transmission line, contribute to New Jersey’s renewable energy goals, and strengthen the electrical grid in the Mid-Atlantic region.
