Danbury’s FuelCell Energy said it has won a contract to build 11 of its fuel cell plants on Long Island.
Long Island Power Authority has agreed to purchase the electricity from units, which have a combined capacity of 39.8 megawatts, for the next 20 years.
The fuel cells would be located in three different areas.
Financial terms of the deal were not disclosed.
FuelCell’s share price jumped 18 percent to $1.71 on the announcement Wednesday — its highest in about three months. On Thursday afternoon, its stock was trading around $1.57.
CEO Arthur “Chip” Bottone said the projects will enhance power generation and resiliency needs.
