Hydropower generation from April through August 2026 was a full 28 percent lower than the 10-year average and 19 percent lower than during the same period last year.

Midwest ISO and Southwest Power Pool Will Merge

LCG, Feb. 25, 2002--The directors of the Midwest Independent Transmission System Operator Inc. (ISO) and Southwest Power Pool Inc. (SPP) gave their approval to a merger of the two power transmission grid managers.

The resulting organization would have responsibility for transmission operations in twenty states and in the Canadian province of Manitoba. The Midwest ISO projects that it will submit required documents to FERC by March 15, and finalize the merger by the close of the second quarter.

The nonprofit Midwest ISO is currently negotiating with the for-profit Alliance RTO, following a December order from FERC for the two to merge, based on transmission bottlenecks that could persist if the two remained separate.

Some state representatives have asked for more justification for FERC's emphasis on the RTO concept. FERC, which is making the right of utilities to compete in deregulated power markets dependent on their membership in an RTO, will release a cost-benefit study next week, according to a spokesman.

Negotiations over the possible terms of a Midwest-Alliance merger were held up most recently when members of the Midwest ISO found Alliance's proposed transmission rates unacceptable. The Alliance RTOs members include Indiana Michigan Power Co., American Electric Power Co Inc., and Northern Indiana Public Service Co.
