WAPA's Desert Southwest Region said it plans to join CAISO's Western Energy Imbalance Market, further splitting the PMA's regions between the ISO and SPP.

SPP’s Western real-time energy market has attracted another participant in Colorado Springs Utilities, which is also interested in full RTO membership.

The U.S. DOT issued guidance on working with its state counterparts to facilitate the use of existing highway rights of way for building transmission lines.

SPP said that a planned expansion into the West has attracted another potential member in WAPA's Colorado River Storage Project.

CAISO’s Western EIM notched another milestone as it welcomed the country’s largest municipal utility and extended its border to include much of New Mexico.

A Nevada bill intends to increase transparency around how much renewable energy the state is producing and how much of it is sold to other states.

Utilities are hoping their participation in SPP's WEIS market will be the "first step" to full RTO membership.

SPP successfully launched its WEIS market, making it the first RTO with power markets in both the Western and Eastern Interconnections.

FERC handed SPP an early Christmas present when it approved the RTO’s second version of a tariff for its five-minute WEIS market.

A discussion on diversity in the energy industry, hosted by CREPC-WIRAB, delved into resource adequacy and the potential for a Western RTO.
