SPP won FERC approval to add three new members in the Upper Great Plains, an expansion that restores the RTO’s scope after its loss of Entergy to MISO.

A round-up of news from the PJM Operating Committee on Sept. 4, 2014.

PJM is hesitating on plans to introduce more sophisticated modeling of combined-cycle plants because of an inability to quantify potential savings and reports of escalating prices.

MISO has agreed to withdraw a unilateral proposal to amend the MISO-PJM joint operating agreement (JOA) after PJM officials expressed concern that it was overly broad.

The California ISO’s expansion of its energy imbalance market to six other states have some asking the question: Is this the beginning of an RTO West?

After a record-breaking winter in which it narrowly avoided load shedding, PJM says it is confident it can keep air conditioners running this summer. But forward prices suggests costs may be higher than last year.

PJM wasn’t the only place the winter 2013-14 made its mark in the record books. MISO, the Southwest Power Pool and NYISO all hit all-time winter peaks during January’s polar vortex, while ISO New England came up just short.
