Energy Project Development

California’s energy market is complex and dynamic, and will evolve and expand significantly in the coming decades. California is also a unique legal and regulatory environment for siting, constructing, and operating energy projects of all types. Downey Brand attorneys are valued by clients and co-counsel headquartered both in- and out-of-state for our expertise in California requirements for all aspects of energy project development and operation.

Our attorneys have broad experience representing clients who operate conventional and renewable generating plants and who participate in the energy market. We counsel clients on generation facility siting, project finance, environmental permitting and litigation defense, greenhouse gas and other pollutant credits and trading, power purchase agreements, interconnection, and electric transmission. We have also represented a variety of energy clients before the California Public Utilities Commission and other regulatory bodies. We can provide legal advice through the entire development process, from market assessment, regulatory compliance, commercial agreements, and project siting, permitting and development, and regulatory policy monitoring to ensure changing regulations do not pull the rug out from under a project.

Renewable Energy Sector

Our experience in renewable energy resources extends to solar thermal, small- and utility-scale photovoltaic solar, wind, geothermal, biomass, and hydroelectric resources. Our attorneys have the expertise and experience to assist clients in virtually all aspects of developing emerging sectors of California’s energy market, such as offshore wind, including the crucial state-level planning for resource and transmission development. In addition to our expertise in the areas necessary to bring offshore wind projects online, our attorneys have in-depth knowledge of the issues that will be integral to building out California’s ports to enable assembly and transportation of offshore wind turbine generator units, including the public trust doctrine and the regulatory and environmental requirements for waterfront development.

Conventional Energy Sector

We have extensive experience representing clients that own and operate crude and refined petroleum product production and transportation facilities, natural gas storage and transmission facilities, and gas-fired generation plants.

Facility Siting

We obtain right-of-way easements from private and public entities as needed for pipelines, transmission lines, power generation stations, and oil and gas facilities. We also conduct environmental and title due diligence, facilitate land purchase and financing, and navigate local and state agency approval processes.

Environmental Permitting

Our attorneys have in-depth experience with all aspects of CEQA and NEPA permitting and compliance, as well as other state and federal regulatory requirements, including those under the Clean Air Act, Clean Water Act, common law Public Trust Doctrine, and federal and state Endangered Species Acts. We routinely assist clients in evaluating the appropriate level of environmental review for a project and assessing compliance strategies; we also evaluate negative declarations, environmental impact reports, and environmental impact statements for legal adequacy and revise those documents as needed to ensure compliance and minimize litigation risk. We advise clients in the preparation of applications, negotiation of conditions, and establishment of compliance programs for permits, including those issued for the operation of air emissions sources under the Clean Air Act; and for discharges of water or dredge-and-fill under the Clean Water Act and California’s Porter-Cologne Water Quality Control Act.

Environmental Litigation

When necessary, we litigate CEQA, NEPA, and related environmental challenges in both state and federal courts and in administrative proceedings before state and federal regulatory agencies. Our attorneys have successfully defended many projects at trial and on appeal, including before the California Supreme Court and the Ninth Circuit Court of Appeals.

Air Pollutant Credits and Trading

Our air quality attorneys have extensive experience advising clients regarding California’s greenhouse gas reporting system and Cap-and-Trade program. We have also helped clients reach solutions with regulators to promote California’s greenhouse gas reduction goals while also ensuring that business operations remain feasible.

Interconnection and Power Purchase Agreements

Our energy regulatory attorneys advise independent renewable and conventional generators on the details of power purchase agreements and interconnection agreements. We also guide clients through the federal and state regulatory requirements that affect the economic and legal viability of generating facilities and renewable energy projects.

Transmission Projects

We have provided key regulatory advice and representation to independent transmission developers throughout the approval and development of their innovative and privately financed transmission projects.  Our representation has included CPUC environmental review and construction approval, and wildfire safety compliance.
