The US city of Alexandria has contracted Wärtsilä to supply a gas-fired power plant for the long-term supply of peaking power.

Under the contract, Wärtsilä will supply a power plant based on seven of its 34SG engines. The plant will extend the existing D. G. Hunter generating station in the Louisiana city.

"This expansion of our power plant will provide Alexandria citizens an efficient long-term power supply utilising existing staff, facilities and partnerships," Jacques M. Roy, Mayor of Alexandria, said. "These units will have the capability of powering critical infrastructure for the city in the event of a major grid failure due to storms or other natural disasters.

"The project will also ensure Alexandria remains diverse in fuel sources, while increasing insulation from unexpected changes in the power supply market."

The City of Alexandria has recently become a part of MISO, the Midwest Independent System Operator. Wärtsilä says that the generation sets will be able to respond quickly to peaks in demand.
