Williams Mullen’s Energy Practice brings together a multidisciplinary team with deep industry insight to support clients navigating the rapidly evolving landscape of traditional and emerging energy markets. As regulatory frameworks shift, technologies advance, and market forces accelerate the energy transition, we work closely with clients to understand their strategic priorities, anticipate risks, and deliver practical, business-oriented legal solutions.
Our practice integrates the capabilities of seasoned energy attorneys with professionals across the firm—including corporate, real estate, land use, finance, mergers and acquisitions, construction, tax, environmental, government relations, and litigation—to provide seamless support at every stage of an energy project or transaction. Whether guiding a project from greenfield development to commercial operation or advising on the acquisition, disposition, or financing of complex assets, our team offers comprehensive, end-to-end representation.

- Power Purchase Agreements, Energy Service Agreements, and offtake structures
- EPC, construction, procurement, and supply-chain matters
- Real estate, land use, and site control
- Conventional and renewable electric generation, transmission, and distribution
- Fuel and commodity procurement, transportation, and logistics
- Energy supply structures for data center projects, including dedicated generation, multi-resource procurement strategies, and grid-interconnection solutions
- Tax structuring, incentives, and project finance
- M&A, joint ventures, and strategic investments
- Rate cases, tariff matters, and market design
- Commercial contracting and sourcing
- Infrastructure development and grid modernization

We represent a broad array of industry participants, including public and private developers, commercial and industrial (C&I) energy consumers, data center operators, electric cooperatives, independent power producers, utilities, energy marketers, financial institutions, EPC contractors, and municipalities.
Our experience spans the full lifecycle of energy development and the full spectrum of energy technologies. This includes the generation, interconnection, purchase, sale, and transmission of electricity from solar, wind, natural gas, oil, coal, and coal-based products; the rapidly expanding areas of nuclear energy—particularly small modular reactors (SMRs); and the development, purchase, sale, operation, and transmission of electricity from projects utilizing battery energy storage, hydrogen, waste-to-energy, carbon capture and storage (CCUS), microgrids, distributed energy resources (DERs), and grid-scale technologies. We help clients navigate the legislative, regulatory, commercial, and financing frameworks that shape these markets and position them for long-term competitive success.
Our attorneys routinely represent clients before state utility commissions and regional transmission organizations (RTOs/ISOs) on matters involving project development, transmission line approvals and siting, interconnection, ratemaking, market participation, grid reliability, transmission planning, market-based rate authority, and energy, capacity, and ancillary services. We bring extensive experience with PJM, NYISO, ERCOT, and MISO markets, including participation, eligibility, aggregation, and compliance requirements.
Recognizing that every project must align with unique regional, technical, and commercial factors, we deliver tailored, practical solutions informed by the full breadth of our firm’s capabilities and our deep understanding of the energy sector.
