Dynamic Line Ratings use sensors to determine how much electricity a transmission line can safely transmit
WASHINGTON, DC – Today, the Federal Energy Regulatory Commission (FERC) announced an advanced notice of a proposed rulemaking aimed at guiding transmission providers to implement Dynamic Line Ratings (DLR), a technology that determines the true, real-time capacity of a power line.
“Transmission operators aren’t maximizing the potential of our power lines, leading to unnecessarily high energy costs for consumers,” said Caitlin Marquis, Managing Director at Advanced Energy United. “Dynamic Line Ratings are one of the most cost-effective tools we have for getting more out of our existing power grid infrastructure.”
Advanced Energy United joined with other clean energy business associations in filing formal comments to FERC calling for more guidance on DLR use, saying in part that wider use of Dynamic Line Ratings, as well as other grid-enhancing technologies (GETs), would help ensure just and reasonable transmission rates by improving the accuracy of how much electricity can move along transmission lines.
About Dynamic Line Ratings (DLR): Technology that utilizes sensors on a transmission line to consider multiple factors beyond just the air temperature when determining how much electricity a line can safely transmit. DLR sensors measure not only temperature but also wind speed, sunlight exposure and line tension. This comprehensive set of data provides a more extensive evaluation of a power lines' condition than ambient-adjusted ratings (AAR), which are what transmission operators are currently required to use. There have been many studies on DLR; a 2021 review found DLR is over 16% more effective than AARs alone.
The draft advanced notice of proposed rulemaking (ANOPR) seeks comment on both the need for a DLR requirement and on the proposed framework of DLR reforms. Initial comments are due to FERC 90 days after publication in the Federal Register, with reply comments due 30 days later.

FERC Order No. 1920 will improve transmission planning and make it easier for states to improve their transmission grid
WASHINGTON, DC – Today, the Federal Energy Regulatory Commission (FERC) voted to approve new rules aimed at improving long-term regional planning for high-voltage interstate electric transmission lines.
“Families and businesses are paying the price for utilities’ and grid operators’ failure to address our critical electricity infrastructure needs,” said Heather O’Neill, President and CEO at national business association Advanced Energy United. "Building more multi-state transmission lines unclogs the traffic jams on America’s electricity superhighways and unlocks our ability to keep up with our growing energy needs. This FERC Order sends the message that transmission planning needs to change, and recognizes that states deserve a central role in ensuring a reliable electric grid built for the future.”

The Chicago Tribune reports on PJM Interconnection's low grade in the recently released Advanced Energy United Generator Interconnection Scorecard and the direct impacts of the entity's slow grid connection process.
Ninety miles west of Chicago, the corn and soybean fields stretch to the sky, and dreams of the clean energy future dangle — just out of reach. To the east of Route 52, there’s the first phase of the 9,500-acre Steward Creek solar farm, in the works since 2019. To the west, there’s South Dixon Solar, which once hoped to begin construction on 3,800 acres in 2022.

Utility Dive reports on the New York Independent System Operator's newly launched program to integrate aggregations of distributed energy resources (DERs) into wholesale markets. The article quotes Advanced Energy United on its critique of the program's 10 kW limit that restricts access for many clean energy resources.
“FERC’s acceptance of our landmark model is a huge win for grid reliability and energy consumers in New York,” NYISO President and CEO Rich Dewey said in a Wednesday statement.
In its application to revise its market rules to allow DER aggregation, NYISO said the 10 kW threshold “balances the need for efficient administration” of wholesale markets alongside the “value that small facilities can reliably provide the bulk power system.”

Western Regional Electricity Market Progress Continues to be Made
Today, the West-Wide Governance Pathways Initiative Launch Committee released a straw proposal that outlines a plan to establish an independent entity to oversee Western markets, building on the California Independent System Operator’s (CAISO) Western Energy Imbalance Market (WEIM) and extended day-ahead market (EDAM). Clean energy industry representatives from Advanced Energy United, Pattern Energy, and Enel North America applauded the proposal, which will help advance efforts to build a regional transmission organization (RTO) in the West.
