Long Island Power Plants

E.F. Barrett Power Station

Summary

E.F. Barrett is a 384-megawatt natural gas/oil fired steam electric generating facility located on the south shore of Long Island in the Town of Hempstead, Nassau County. Barrett has two generating units that became operational in 1956 (Unit 1) and 1963 (Unit 2)

Barrett uses a once-through cooling system that is responsible for entraining 1 billion fish eggs and larvae each year, and impinging another 176,000 adult and juvenile fish. Of particular concern is Barrett's impact on winter flounder, an important recreational and commercial fish. According to reports provided by National Grid, 40 percent of the estimated annual entrainment of winter flounder by power plants in New York State occurs at E.F. Barrett.

Megawatts Water Withdrawn (million gallons/day) Entrainment (annual) Impingement (annual)
384 294 906,259,233 176,044

Permitting Status:

A draft State Pollutant Discharge Elimination System (SPDES) permit was issued by DEC for public comment in December 2009. The DEC determination to reduce aquatic impacts from the facility's cooling water intake structure was installation and operation of a wet closed-cycle cooling system. Public comments on the draft permit were due by March 24th, 2010.

Far Rockaway Power Station

Summary

Note: In June 2012 the Far Rockaway Power Station was retired.

The Far Rockaway Power Station is a 109 megawatt natural gas/oil fired steam electric generating facility located on the south shore of Long Island in Far Rockaway, Queens County. The power station has one generating unit that became operational in 1953.

Far Rockaway uses a once-through cooling system that is responsible for entraining 118 million fish eggs and larvae each year, and impinging another 6,560 adult and juvenile fish.

Megawatts Water Withdrawn (million gallons/day) Entrainment (annual) Impingement (annual)
109 84 117,662,685 6,560

Permitting Status:

In June 2011, the Long Island Power Authority and National Grid announced that they would retire both the Glenwood and Far Rockaway power plants. Both plants were shuttered in June 2012.

Glenwood Generating Station

Summary

Note: In June 2012 the Glenwood Generating Station was retired.

Glenwood Generating Station is a 210 megawatt natural gas fired steam electric generating facility located on the north shore of Long Island in Glenwood Landing, Nassau County.

Glenwood has four generating units which became operational from 1930 to 1954. Units 2 and 3 have been retired, leaving Units 4 and 5 as the remaining operating generators. Glenwood has recently operated as a peaking facility, generating most of the power during the summer months. The facility's operation decreased from 43 percent in 2001 to 11.2 percent in 2005.

Glenwood employs a once-through cooling system that is responsible for entraining more than 178 million fish eggs and larvae each year, and impinging another 9,500 adult and juvenile fish.

Megawatts Water Withdrawn (million gallons/day) Entrainment (annual) Impingement (annual)
210 179 177,879,210 9,562

Permitting Status:

In June 2011, the Long Island Power Authority and National Grid announced that they would retire both the Glenwood and Far Rockaway power plants. Both plants were shuttered in June 2012.

Northport Power Station

Summary

The Northport Power Station is a 1,522 megawatt natural gas/oil fired steam electric generating facility located on the north shore of Long Island in the Village of Northport, Suffolk County. and nbsp; The power station has four generating units that became operational between 1967 and 1977.

Northport uses a once-through cooling system that is responsible for entraining more than 8 billion fish eggs and larvae each year -- far more than any other power station in the state -- and impinging another 127,000 adult and juvenile fish.

Megawatts Water Withdrawn (million gallons/day) Entrainment (annual) Impingement (annual)
1,522 939 8,430,808,238 127,118

Permitting Status:

Northport's current State Pollutant Discharge Elimination System (SPDES) permit expires in January 2011, and its renewal application is due in July 2010. A determination to reduce aquatic impacts from the facility's cooling water intake structure will need to be made by DEC upon SPDES permit renewal.

Port Jefferson Power Station

Summary

The Port Jefferson Power Station is a 385 megawatt natural gas/oil fired steam electric generating facility located on the north shore of Long Island in Port Jefferson, Suffolk County.

The Port Jefferson facility has two generating units, Units 3 and 4, which were built in 1948 and 1950 respectively. Units 1 and 2 have been in permanent cold standby since 1992.

Port Jefferson employs a once-through cooling system that is responsible for entraining more than 1 billion fish eggs and larvae each year, and impinging another 76,000 adult and juvenile fish.

Megawatts Water Withdrawn (million gallons/day) Entrainment (annual) Impingement (annual)
385 399 1,014,950,951 76,104

Permitting Status:

A draft State Pollutant Discharge Elimination System (SPDES) permit was issued by DEC for public comment in July 2009. The DEC then issued a second draft SPDES permit in June 2011 in which the plant would be required to operate at no more than 15 percent of its electricity generating capacity factor, install variable speed pumps, use aggressive pump shutdown procedures and install a Ristroph screen with a fish return system. The permit also calls for an increased reduction in the plant's impingement and entrainment mortality rates. The draft permit did not call for closed cycle cooling.
