MISO introduces vitality storage to portfolio

Carmel, Ind.-based regional transmission group Midcontinent Impartial System Operator (MISO) has added electrical storage sources to its market portfolio for the primary time because it prepares for a bigger share of renewables to be added to the grid, in accordance with a (Sept. 6) information launch.

The brand new useful resource kind is anticipated to assist reliability and resilience amid the trade transition in sources. Electrical storage sources embody batteries, pumped storage services and compressed air vitality storage.

“We’re excited to see this house develop with growing member curiosity and participation, significantly as we proceed to adapt to the accelerating useful resource transition,” stated Jessica Lucas, MISO’s government director – system operations.

In line with the Federal Vitality Regulatory Fee, electrical storage sources are “able to receiving electrical vitality from the grid and storing it for later injection of electrical energy again to the grid no matter the place the useful resource is situated on {the electrical} system.” In line with the discharge, electrical storage sources are versatile sources that may assist scale back peak calls for, handle congestion and supply backup energy for main disruptions as a result of they will reply rapidly and swap between injection (discharge) and withdrawal (cost) modes.

As a result of MISO has included electrical storage sources in its market portfolio, the sources can take part in MISO’s vitality and working reserves markets as provide and demand.

“The MISO workforce has demonstrated wonderful collaboration with our stakeholders, and the pursuit of artistic options resulted in MISO’s first secured patent,” Lucas stated. “The event of the (electrical storage sources) participation mannequin has been a key ingredient of the market redefinition pillar of MISO’s Response to the Reliability Crucial within the useful resource fashions and capabilities space.”

The near-term advantages of the brand new mannequin are anticipated to be modest amid a small quantity of the storage sources, however the mannequin locations MISO forward of the elevated storage participation that’s anticipated with larger penetration of renewables and distributed vitality sources over the following 5 to 10 years, the discharge reveals.

In line with the U.S. Vitality Data Administration (EIA), 15 gigawatts of recent utility-scale electrical producing capability had been added to the U.S. grid within the first half of 2022. Latest experiences present one other 29 gigawatts of capability are anticipated to be added within the second half of the 12 months. Wind era accounted for about one-third of the capability added within the first half of the 12 months, whereas photo voltaic is anticipated to account for almost half of the era added within the second half of the 12 months.

In line with the EIA, U.S. electrical energy era from renewable sources is anticipated to rise from 22% of electrical energy era in 2022 to 24% in 2023 as extra producing capability from wind and photo voltaic come on-line and different era sources, reminiscent of coal and nuclear, are retired.

MISO manages the electrical grid throughout 15 U.S. states, together with Arkansas, and the Canadian province of Manitoba.
