NERC defended its proposed standard on inverter-based resources from stakeholder criticism on several aspects, including its development process and exemptions for legacy technology.

NERC's Standards Committee agreed to post several standards projects for industry comment, though members expressed concern about a plan to compress their timelines.

NERC said the response to an alert from June 2024 shows many generator owners do not have available, up-to-date information on the capabilities of their inverter-based resources.

The current debate in the U.S. electricity sector pitting efforts to increase renewables against the need for grid reliability in the face of growing demand could be unnecessary and counterproductive, according to one expert.

Industry stakeholders called for a number of revisions to NERC's proposed inverter-based resource ride-through standards, mostly involving the exemption process for legacy inverters.

With data centers already causing “major disturbances” on the grid, the industry could learn lessons from the recent growth and implementation of IBRs, according to a new Elevate Energy Consulting study.

FERC approved four proposed reliability standards: three relating to inverter-based resources and one for extreme weather planning.

To build a reliable, affordable and clean electric power system, the U.S. energy industry and customers will need to shift their thinking about what a reliable system looks like, according to a study from nonprofit think tank Energy Innovation Policy & Technology.

In a filing, NERC told FERC it estimates more than 850 inverter-based resources will need to be registered under new criteria.

Consultant Terry Brinker warns about potentially hundreds of facilities being included in NERC's IBR rules, where fines and penalties can be as high as $1 million a day per violation.
