CARMEL, Ind., May 20, 2011 /PRNewswire/ — ACES Power Marketing (APM) – a
nationally recognized wholesale energy risk management and transaction execution
service company – extended its contract with the City of Roseville, California
(Roseville) through December 31st, 2013. The extension includes an option for
service fee pricing for 2014 and 2015. This contract affirms APM’s presence as a
leading provider of energy risk management services to municipal and public
power utilities, such as APM’s newest customer Okanogan PUD, located in the

long-term risk-hedging strategies.

Middle office services include credit services, contract administration, and
trading controls (including the capture, verification, and monitoring of all
market transactions).

Back office services include the settlement of bilateral and CaISO energy
transactions.

“We’re a satisfied customer,” said Michelle Bertolino, Director of Roseville
Electric. “We continue to believe that APM’s services provide good value for
Roseville, and allow us to do a better job of managing risk, and power and gas
costs.”

“Although we survey customers annually as part of our effort to provide quality
services, the ultimate test of how we are performing comes at contract renewal
time,” added David J. Tudor, President and CEO of APM. “Roseville is a valued
customer, and we are extremely pleased that they chose to continue taking APM
services.”
