is constructing a first-of-its-kind power plant in northern Mississippi
that will work like a giant, highly efficient battery, storing electricity
during periods of low demand and providing it when power usage is high.
TVA has signed a
contract with Innogy Technology Ventures Limited of Great Britain, which
designed the 12-megawatt plant and provided the modules that are used
to store energy. The total cost of the plant is estimated at $25 million.
technology is based on regenerative cells that store energy through a
chemical process. Its trademarked under the name Regenesys.
In November 2000,
the Regenesys technology won the Most Promising Pre-Commercial Technology
Development Award in the Financial Times 2000 Energy Global Awards
competition. The award was conferred by Financial Times Energy, a provider
of energy-industry news and information.
The TVA plant will
be the first one of its type in the United States and will have the largest
regenerative cells ever used.
- The energy-storage
plant is designed to improve power quality by eliminating momentary
interruptions in service and maintaining voltage levels.
- The plant will
enhance system reliability while having a minimal impact on the environment.
- The technology
has the potential to change the way power systems operate by providing
a means of storing electricity for significant periods of time.
- It also will improve
system reliability in the western part of the TVA power system by eliminating
momentary interruptions and maintaining voltage levels.
