Sharyland Utilities, L.P.

What Sharyland Utilities, L.P. does

Sharyland Utilities, L.P. is a Texas-based regulated transmission utility founded in 1999 by Hunter Hunt through Hunt Consolidated Energy, notable as the first greenfield utility created in the United States since the late 1960s. The company operates high-voltage electric transmission infrastructure at 138kV and 345kV within the Electric Reliability Council of Texas (ERCOT) grid, providing wholesale transmission services, distribution substation services, and grid interconnection capabilities to investor-owned utilities, municipally-owned utilities, and electric cooperatives. Its most distinctive technical asset is a 300 MW High Voltage Direct Current (HVDC) interconnection—the DC Tie—commissioned in October 2007 and expanded in 2014, which links the ERCOT grid with the Mexican national grid operated by CENACE near Mission, Texas and Reynosa, Tamaulipas, making it the first commercial interconnection between the Texas and Mexican electrical grids.

Sharyland earns revenue through regulated wholesale transmission rates and distribution substation tariffs set by the Public Utility Commission of Texas (PUCT), with rates determined through regulatory proceedings under its filed Transmission Service Tariff (effective November 14, 2025). The company's go-to-market is enterprise field sales and direct B2B engagement with ERCOT market participants, with major project development executed through joint venture structures with partners including Electric Transmission Texas (ETT), AEP Texas, and Hunt Power. Sharyland's project portfolio includes the Cross Valley Project (placed in service June 2016), the completed Second Circuit Upgrade (May 2024), the PUCT-ordered Lower Rio Grande Valley Upgrade projects (September 2021), and the proposed La Palma to Kingfisher Transmission Line Project expected in mid-2026, which will close a critical loop in the South Texas regional transmission system.

Privately held by the Hunt family through Hunt Consolidated Energy, Sharyland is headquartered in Dallas, Texas with operational sites across South Texas including Mission, Brownsville, and San Benito, and a workforce of 251-500 employees. The company has executed notable historical transactions including the 2010 acquisition of Cap Rock Energy and the May 2019 closing of a transaction with Sempra Energy. Its competitive moat rests primarily on its regulatory franchise as a PUCT-regulated transmission-only utility and the unique HVDC interconnection with the Mexican national grid.

Expansion highlights5 records

Broad incumbents

• Vistra Corp: Texas-headquartered competitive power generator and retail electricity provider with significant ERCOT footprint. Comparable as a major ERCOT market participant and counterpart for transmission services, though it owns generation rather than transmission.
• CenterPoint Energy: Large Texas-based electric and gas utility with significant Houston-area transmission and distribution operations in ERCOT. Competes for regulatory, capital, and customer mind-share in the Texas utility market.

Direct peers

• LCRA Transmission Services Corporation: Lower Colorado River Authority's transmission arm operating high-voltage transmission lines across Texas, including ERCOT. Directly comparable as a non-IOU transmission provider operating in overlapping Texas corridors.
• NextEra Energy Transmission: Subsidiary of NextEra Energy developing and operating transmission assets across multiple US ISOs/RTOs. Comparable as a pure-play transmission developer competing for similar PUCT-approved and FERC-regulated projects.
• AEP Texas: AEP's regulated Texas transmission and distribution utility operating within ERCOT. Sharyland and AEP Texas are actively co-developing the La Palma to Kingfisher 345 kV project and share regulatory engagement.
• Oncor Electric Delivery Company: Largest regulated T&D utility in Texas, serving the ERCOT region. Sharyland's CEO spent 31 years at Oncor, and Oncor is a natural benchmark for transmission rates, ERCOT operational practices, and PUCT regulatory dynamics.
• Electric Transmission Texas (ETT): Joint-venture transmission utility in ERCOT owned by AEP and Berkshire Hathaway Energy. Sharyland co-developed the Cross Valley Project with ETT and operates overlapping 345 kV infrastructure in the Lower Rio Grande Valley.

Others

• Hunt Power: Sharyland's affiliated entity and co-developer under Hunt Consolidated Energy. Comparable for understanding Sharyland's parent strategy, capital allocation, and shared innovation in transmission financing (e.g., REITs).

Emerging players

• Pattern Energy Group: Renewable energy and transmission developer with US project pipeline including ERCOT-adjacent assets. Comparable as an emerging participant in Texas transmission build-out and cross-border interconnection projects.

Regional players

• South Texas Electric Cooperative: Generation and transmission cooperative serving members across South Texas in overlapping ERCOT territory. Comparable as a non-IOU transmission operator in the same Lower Rio Grande Valley region.
