About Niagara Mohawk Power Corporation

Niagara Mohawk Power (which does business as National Grid) distributes electricity to approximately 1.6 million customers and natural gas to about 600,000 customers in upstate New York. The company owns and operates power transmission and distribution lines; wholesale activities on its transmission grid are managed by the New York ISO. Niagara Mohawk Power is a provider of last resort for customers who do not choose an alternative supplier in New York's deregulated power market. Niagara Mohawk Power is a regional operating subsidiary of UK-based National Grid, which delivers electricity to 3.5 million customers in Massachusetts, New York, and Rhode Island.


Niagara Mohawk Power is engaged in the transmission of electricity and distribution of electricity and gas. It owns and operates 50 electricity generation units on Long Island that provide 3,800 MW of power under contract to LIPA. Its plants consist of oil and gas fired steam turbine, gas turbine and diesel driven generating units with capacities ranging from 2 MW to 385 MW.

Parent National Grid owns and operates a 8,700 mile electricity transmission system with 100 miles of underground cable and 522 substations. The parent company also maintains and operates the electricity transmission and distribution system on Long Island owned by LIPA, covering 1,230 square miles.

The parent company owns and operates electricity distribution networks in upstate New York, Massachusetts, and Rhode Island.

In a bid to lower demand and carbon emissions, the company is pursuing a strategy of offering rebates to customer who replace old inefficient gas appliances (heaters, furnaces) with new, efficient ones. Niagara Mohawk Power is looking to have customers cut their energy consumption by 3%. The customer benefits through a cash incentive and by cost savings in the long run. It is also introducing smart grid technology (automated meters) to improve the efficiency of its power distribution operations.

In 2013 it added 29,925 new gas heating customers (most switching from more expensive electric service).

That year Niagara Mohawk Power and the EPA finalized a plan to clean up additional contaminated soil and ground water at the Niagara Mohawk Power Superfund site in Saratoga Springs, New York.

Company Background

In 2011 the company got the go-ahead to raise rates to increase revenues, in part, to cover the lost revenues resulting from conservation and green energy initiatives.

Niagara Mohawk Holdings (the immediate parent of Niagara Mohawk Power) was acquired by National Grid in 2002. National Grid USA transmits and distributes electricity and natural gas to more than 6.7 million customers in Massachusetts, New Hampshire, New York, and Rhode Island.

The Holdings company was formed in 1937 to serve primarily rural and upstate power customers in New York State.
