Gridliance

What Gridliance does

GridLiance is an independent, US-focused electric transmission infrastructure company and a subsidiary of NextEra Energy Transmission, operating as the first independent transmission-only utility built to partner with municipal utilities, electric cooperatives, joint action agencies, and power producers. Founded in 2014 and headquartered in Chicago, the company owns and operates more than 700 miles of high-voltage transmission lines (765kV, 230kV, 161kV, 138kV) and related substation infrastructure across six states: California, Illinois, Kansas, Kentucky, Nevada, and Oklahoma, with additional pipeline projects extending into Minnesota and Wisconsin. GridLiance is organized through three regional operating subsidiaries: GridLiance West (CAISO region, 167 miles in California/Nevada), GridLiance High Plains (SPP region, more than 450 miles in Kansas/Oklahoma), and GridLiance Heartland (MISO region, Illinois/Kentucky), each operating under FERC Formula Rate revenue requirements with functional control by their respective RTO/ISO.

The company's core business is developing, owning, and operating regulated transmission assets, with revenue generated through FERC-approved Formula Rate mechanisms that recover cost-of-service plus an allowed return on equity, adjusted annually through true-up filings. GridLiance's growth model combines asset acquisitions from cooperatives and municipal utilities (Tri-County Electric Cooperative, Valley Electric Association, Electric Energy Inc.) with greenfield project development and consortium-based regional transmission expansion, exemplified by the $1.658 billion MISO Tranche 2.1 portfolio award (43% GridLiance share) and the MariBell 765kV/161kV project with Dairyland Power Cooperative. The company is privately held with 11-50 employees, leveraging parent-company capital, regulatory expertise, and engineering relationships to deliver reliability improvements, grid hardening, and renewable-energy interconnection across its regional footprint.

Regional players

• ENRT (Energy by National Resources): ENRT is an emerging transmission developer with project footprints in MISO and PJM. Its regional scope, partnership-driven business model with cooperatives, and FERC-regulated profile align with GridLiance Heartland's cooperative-focused approach.
• TransCanyon (Glen Canyon): TransCanyon develops transmission projects connecting Utah, Wyoming, and the broader Western grid. Comparable as a smaller, focused transmission developer operating under regulated frameworks in a geography adjacent to GridLiance West's CAISO footprint.

Broad incumbents

• Hydro-Québec TransÉnergie (US): Hydro-Québec's transmission arm has explored cross-border and Northeast interconnection projects. It is comparable as a vertically integrated utility leveraging regulated transmission assets to serve wholesale markets analogous to GridLiance's cooperative model.
• NextEra Energy Transmission: As GridLiance's parent and broader transmission platform within the NextEra Energy family, NextEra Energy Transmission coordinates enterprise-wide transmission strategy and large-scale project bids. It is the parent/strategic peer providing capital and regulatory access.
• AEP Transmission: AEP Transmission is a large regulated transmission business within American Electric Power covering multiple RTOs (PJM, MISO, SPP). It competes with GridLiance for regional transmission project awards and operates comparable high-voltage line portfolios.

Direct peers

• ITC Holdings: ITC Holdings operates as an independent transmission-only developer and owner across multiple US regions (MISO, SPP). It is the closest functional analog to GridLiance, pairing FERC-regulated transmission rates with high-voltage infrastructure investment.
• American Transmission Company (ATC): ATC is a multi-state independent transmission operator serving MISO in the upper Midwest, comparable to GridLiance Heartland. It develops and owns high-voltage transmission infrastructure with regulated, FERC-approved returns similar to GridLiance's formula-rate model.
• LS Power: LS Power develops, owns, and operates transmission infrastructure including HVDC and EHV AC projects across multiple ISOs. Its transmission arm competes with GridLiance for MISO/SPP/CAISO regulated project awards and partnership opportunities with utilities and co-ops.

Emerging players

• Anbaric Development Partners: Anbaric is an independent transmission developer focused on clean energy interconnection and offshore wind integration. It competes in adjacent regulated and merchant transmission RFPs where GridLiance also pursues renewable interconnection opportunities.
• Invenergy Transmission: Invenergy has expanded into transmission development to pair renewable generation with grid interconnection assets. Its transmission strategy mirrors GridLiance's positioning for renewable energy integration across RTO markets.
