5 September 2002 – Green Mountain Energy Company, US retail provider of cleaner energy, today announced that it would soon begin marketing its pollution-free Green Mountain Energy electricity to customers in New York — the eighth state in which the company’s cleaner electricity is available. Niagara Mohawk customers in upstate New York can now choose 100 per cent pollution-free electricity said Green Mountain Energy Company.

Green Mountain Energy Company has entered the state of New York as a result of a new renewable energy program in which Niagara Mohawk residential and commercial customers can choose to have their electricity produced by less-polluting, renewable sources — wind and hydropower — without switching electric providers. This new program for renewable energy is part of the Niagara Mohawk-National Grid merger and was approved by the New York State Public Services Commission on May 22, 2002.

“We are thrilled to bring Green Mountain Energy electricity to the state of New York and offer our product to Niagara Mohawk customers,” said Paul Thomas, chief executive officer and president of Green Mountain Energy Company. “We are excited about the opportunity to grow and expand our business by entering a new key state, which helps us further our company’s mission to change the way power is made. This major milestone is especially satisfying given that Green Mountain Energy Company just celebrated its five- year anniversary.”

All Niagara Mohawk residential and commercial customers are receiving more information on the program and an enrolment form in their September bill, which began arriving in the mail this week.

In order to meet all of their electricity generation needs, customers can now purchase Green Mountain Energy electricity through Niagara Mohawk. After a customer signs up for Green Mountain Energy electricity, Niagara Mohawk will be notified of the customer’s decision. The surcharge for this pollution-free electricity will be included as a line item on the customer’s Niagara Mohawk bill. Niagara Mohawk will continue to deliver the customer’s electricity and provide customers service, including energy-related emergency response and monthly billing.

Green Mountain Energy Company will be offering 100 per cent pollution-free electricity that will consist of 85 per cent hydropower and 15 per cent wind and will be generated from renewable resources in the state of New York.

“The shift to renewable energy, and the environmental benefits that it can provide, will be driven by consumer demand,” said William F. Edwards, president of Niagara Mohawk, a National Gird company. “By sponsoring this program, Niagara Mohawk is leading by example in promoting access to less- polluting sources of energy.”

Thomas adds that the synergy between Green Mountain Energy Company and Niagara Mohawk are strengths of the renewable energy program.

“This is a win-win situation for customers,” Thomas said. “They remain with Niagara Mohawk, receiving the reliability they’ve come to trust. Meanwhile they’re able to choose pollution-free electricity that is produced entirely in the state of New York. Each of them will help clean the air we breathe by reducing a portion of the carbon dioxide (CO2) their home would otherwise emit.”

Niagara Mohawk, a National Grid company, provides electric service to 1.5 million customers and natural gas to 540 000 customers in upstate New York. The company is based in Syracuse. Its parent company also has distribution operations in New England. National Grid Group plc. is an international U.K.-based company that builds, owns and manages electricity and telecommunication networks.
