Niagara Mohawk: A National Grid Company

Niagara Mohawk Power Corporation is a utility company located in a beautiful part of upstate New York. Having been acquired by National Grid in 2002, Niagara Mohawk assisted the expansion of National Grid’s customer base. 

Now serving nearly 20 million electricity customers and close to 3.6 million gas customers in the Northeast, including upstate New York, National Grid’s Niagara Mohawk Power Corporation has become a prominent power supplier throughout New York, Massachusetts, and Rhode Island.

Customers in this region are not inhibited from receiving energy supply from National Grid or discouraged from exploring alternative options from energy services companies (ESCOs).

Understand National Grid and deregulation in New York

National Grid’s services expand beyond the state of New York. The company handles energy markets in Rhode Island and Massachusetts. National Grid also owns several other utility companies, including New England Power Company, Boston Gas Company, and Keyspan Gas East Corporation.

Residents in the National Grid service area may decide whether the utility will supply their home or business with natural gas and electricity. During the late 1990s, the state of New York had decided to deregulate their energy markets. This change enabled consumers the opportunity to receive energy supply from their local utility company or from potentially more competitive plans offered by ESCOS. 

For clarity, it is important to notice that there are differences between a utility and an ESCO. Regulated supply rates are only available through the utility company, whereas an ESCO may offer competitively priced supply plans, various contract lengths, and green energy products.
