Feb 12 The California Independent System
Operator and PacifiCorp have signed an agreement to expand the
real-time energy imbalance market to take advantage of growing
renewable resources in the U.S. West, officials said Tuesday.
"Increased coordination of energy systems in the West is
critical if we are to meet important challenges such as ensuring
reliability, keeping costs down for customers and effectively
integrating renewable resources," Greg Abel, chief executive of
Portland-based PacifiCorp, said in a statement.
Pacificorp, a unit of MidAmerican Energy Holdings Co,
operates utilities in California, Oregon, Washington, Utah,
Wyoming and Idaho.
Through more frequent dispatch of power generation to match
actual electric demand across a broader geographic region,
officials said the voluntary energy-imbalance market will better
utilize the growing amount of available wind and solar power.
The memorandum of understanding signed by PacifiCorp and the
ISO is expected to lead to a formal agreement to be considered
by the ISO Board of Governors in March.
The groups plan to implement the expanded imbalance market
by October 2014.
