Regenesys Electricity Storage Technology
United Kingdom. Progress with construction of the Little Barford Regenesys plant is shown in
Figure 7.
Of the total storage capacity, 40MWh is reserved to provide black start for the Little Barford
station. The economic benefit for black start is the subject of a proprietary arrangement between
Innogy and National Grid. Innogy also plans to demonstrate the utility of the Little Barford plant
for energy management (arbitrage), and for response (load following) and voltage control for the
power network. Innogy regards the Little Barford plant as a demonstration project, however, and
has not attempted to economically justify the plant on the basis of the benefits that can be
garnered by it. From publications relating the to Didcot project (see above) and other sources,
we think that the cost of the Little Barford Plant will be in the range of $25-40 million.

More recently, Innogy has also contracted to supply TVA with a 12MW, 120MWh Regenesys
system that is to be used primarily to provide a higher level of reliability of electrical service to
the Columbus Air Force Base (CAFB) in Mississippi. 3 By mid-2002, according to a TVA
spokesman, concrete had been poured, some buildings constructed, tanks were already in place,
