Project Execution from Concept to Operation
Sargent & Lundy is a leader in the renewable energy sector. Our decades of experience mean our clients can trust us to provide knowledgeable, independent, and comprehensive support for evaluating, planning, designing, and deploying renewable energy and energy storage technologies.
Our services cover all renewable energy technologies for global projects of all sizes. We actively work with clients in every project lifecycle stage—from initial planning to procurement to ongoing maintenance—providing innovative solutions to their challenges. We serve as lender’s engineer, full-design architect-engineer, owner’s engineer (OE), and advisor. Our work spans technical, financial, contractual, environmental, and permitting matters and third-party reviews and analyses.
Renewable Energy Technologies
Our industry experience includes:
- Presenting at major conferences and technical meetings, including the 2012–2019 American Wind Energy Association (AWEA) WINDPOWER conferences.
- Serving as part of a North American Electric Reliability Corporation (NERC) working group called “System Planning Impacts from Distributed Energy Resources,” which focuses on supporting the increasing penetration of distributed energy resources (DERs) into the bulk power system.
- Helping establish national guidelines and standards. We were part of the American Society of Civil Engineers (ASCE) and AWEA committee that prepared a U.S. guideline for wind turbine foundation design. We are actively involved in developing the IEC 61400-6 standard for onshore wind turbine foundation design.
Since the early 2000s, we have provided services for project developers, contractors, owners, lenders, and investors, including site screenings, project feasibility studies, resource assessments, independent engineering, interconnection planning, conceptual engineering, contract development, detailed engineering, design reviews, construction monitoring, commissioning, and operations and maintenance (O&M) support.
Sargent & Lundy has supported solar projects since the late 1980s to include the BOP design engineer for the SEGS VIII, IX, and X facilities in California. Our long, successful history includes both photovoltaic (PV) and concentrating solar power (CSP) projects, providing owner’s engineering, independent engineering technical due diligence, and detailed design of solar energy generation. We also have considerable experience supporting the integration of solar and energy storage projects.
Sargent & Lundy’s work with energy storage systems includes industry-leading experience on battery storage system projects; a wide variety of battery storage systems, from some of the world’s largest battery storage system projects to small behind-the-meter systems; and the integration of battery storage systems with solar and other generation forms. We have experience with multiple storage technologies, including liquid-air energy storage, advanced compressed air energy storage, flow batteries, and hydrogen (for energy storage and for use as a fuel). We assist clients with technology selection and evaluation, use case analysis, procurement, design and engineering, construction management, interconnection support, permitting support, independent engineering due diligence, advisory, asset transaction services, O&M support, decommissioning support, and related services.
Sargent & Lundy has provided engineering support and services for all types of hydrogen projects over several decades, including hydrogen systems tied to various power sources like solar, wind, hydro, and nuclear. Our project capabilities consist of hydrogen production via electrolysis (polymer electrolyte membrane [PEM], alkaline, and solid oxide electrolysis cells [SOECs]) as well as compression, storage, blending, offloading, and other use cases. We also support hydrogen use cases for producing alternative fuels like ammonia, e-methanol, or sustainable aviation fuel (SAF). Our experience encompasses pairing different hydrogen technologies with common balance-of-plant systems, designing communication and electrical systems for seamless facility integration, hydrogen demand modeling, and forecasting.

Biomass, Biofuels, Alternative Fuels, and Recycling
Sargent & Lundy’s involvement in the alternative fuels industry includes feasibility studies, fuel supply assessments, evaluations of technology options, siting evaluations, identification of “target” emission rates for air permitting activities, layouts, cost estimating, and other conceptual design activities. In addition, we have also investigated waste-to-energy projects and alternative fuels co-firing in existing units and new unit designs.
For hydroelectric power projects worldwide, our roles have included lender’s technical advisor, OE, and IE. Previous experience includes reviewing hydrology and energy production estimates; conducting technical, environmental, and asset acquisition due diligence reviews; and construction and performance test monitoring. We have performed over 70 construction monitoring and operations monitoring site visits.
Previous roles for geothermal projects have included OE, lender’s technical advisor, and IE. We have worked in both the generation (geothermal power) and energy distribution (deep direct use and residential/commercial district heating) sides with a range of focuses, including individual power plants and international geothermal energy market studies. We have reviewed energy production estimates, conducted technical and environmental due diligence reviews, and prepared feasibility studies for the use of geothermal energy for electricity production or steam generation.
Sargent & Lundy performs feasibility study, owner’s engineering, and detailed engineering of microgrid projects. We use our experience with all the technologies typically considered for use in microgrids—solar PV, diesel engines, microturbines, reciprocating engines, battery storage systems, wind turbines, and combustion turbines. Many of these technologies may capture the waste heat and operate in a combined heat and power mode to send steam or hot water to nearby homes or businesses. Our experience also includes integrating different technologies and designing the communication and electrical systems to connect the different resources.
