Swiss pumped energy installation planned
October 30, 2009Alstom Hydro has been awarded a euro 178 million contract to provide four 250-megawatt variable speed pump turbine and motor generator units for an installation in
Philippe Joubert, president of Alstom Power, said in statement released by the company, “Pumped storage can help
When demand for electricity is low, excess power is used to pump water into a higher reservoir. When demand for power is high, the water in the higher reservoir is released through a hydroelectric turbine, generating electricity that can be sold at premium prices.
A variable speed pump turbine regulates the level of energy the pump turbine consumes, thus giving utilities more control over their resources. Variable speed also helps reduce the number of starts and stops and helps to regulate the network frequency or voltage in pumping mode.
Pumped storage technology is an efficient and flexible large-scale power storage technology, according to Alstom, and enables utilities to respond quickly to fluctuating power demand and to manage demand peaks. To date, there are over 127 gigawatts of pumped storage in operation around the world.
Alstom’s agreement is with the canton of Glarus and with Kraftwerke Linth-Limmern AG, a partner of Axpo AG, the largest producer of hydropower and electricity in
Alstom Hydro, a joint venture between Alstom and Bouygues, has over 400 gw of turbines and generators installed worldwide, or more than 25 percent of the total global hydropower installed capacity, according to the company. Turbines, generators and related power industry components are typical heavy lift or project cargoes.
