Ian Grant, TVA Project
Manager, provided us with an update of the Regenesys Energy Storage
System and showed photographs of the system under construction. He said that
storage of electricity on a large scale offers a range of benefits to power
utilities but few technologies are available for energy storage in the multi-MWh
range. Those that have been successful to date are pumped storage, compressed
air, and lead acid batteries (up to 10-20 MW). Several new battery technologies
now in development offer improvements over lead-acid, including the Regenesys
Flow Batteries that use two liquid electrolytes as a means of energy storage.
The first full-scale Regenesys unit is approaching completion in England. A
second unit with 12 MW steady state and 19 MW peak rating is being constructed
for TVA to improve supply to the Columbus Air Force Base. Ian compared
contending storage technologies and the factors and benefits considered by TVA
in making its choice, and progress on construction of the Columbus unit. Ian
discussed why Regenesys was selected from all the storage technologies
available. He showed graphically the advantages of an energy storage system over
upgrading transmission service in other ways. He said that among Regenesys’
benefits are a fast response time and high ramp rate.

PROPOSED BY-LAW
CHANGES______________________________________
To maintain better
continuity for the CEC bookkeeping work, a number of past CEC presidents have
proposed to make the position of Treasurer one that is held for longer than a
year. The position would be appointed by the Executive Committee and would be
held by someone who would volunteer to take on the associated bookkeeping task
for an extended period of time. To change the way the treasurer is chosen
requires a change in the CEC constitution and by-laws. The proposed changes can
be seen by clicking on the appropriate link on our web site at www.chattanooga.net/engineer/CEC .
Also shown are proposed minor changes to some of the officer duties. A vote on
the proposed changes will be held at our regular meeting on October
21.
ELECTION OF OFFICER
______________________________________Election of officers for next year will be held at our regular meeting on November 25. If you are interested in being a candidate or would like to suggest someone as candidate, please get in touch with Lulu Copeland (copeland@chattanoogastate.edu or 697-3212) or Jack Wagner (wagnerja@epb.net or 648-3594). Of particular need is the filling of the position of Secretary for next year.
