Power & Renewable Energy expertise

Renewable Generation

The nation’s progress toward a decarbonized electric system is expected to continue in the foreseeable future, as developers and others work to balance affordability, reliability, and sustainability goals. Renewable energy power plants are currently the fastest-growing energy source in the US, with solar and wind leading new power plant construction. Atwell offers comprehensive solutions for utility-scale solar, wind, and distributed energy resources, supporting the transition to a more sustainable energy landscape.

Energy Storage

US demand for energy storage systems will grow sixfold by 2030. Having consulted on more than two gigawatts worth of energy storage projects, Atwell is a leader in the application and operation of these systems. We perform studies to evaluate the potential benefits of energy storage for clients, recommend sizes, and estimate economic impacts. Our solutions are designed to operate effectively in markets with irregular loads, addressing these challenges head-on. With the right battery energy storage systems (BESS), utilities can defer costly infrastructure expansions and provide more reliable power to communities. Our team can execute every step of the project, from feasibility to operation.

Generation Interconnection

Atwell has a long history of partnering with our utility and independent power producer clients through complex design and engineering renewable programs and projects. Many of these projects require a connection to the bulk electric system which Atwell makes possible through our transmission and substation capabilities.

Utility Power Delivery

We help our utility clients improve the quality, safety, and resiliency of power delivery with services to support every step of project development. The transition to clean energy and electrification has created an unprecedented need for new and expanded networks, system upgrades, and design innovations. Atwell has partnered with more than 65 utilities to expand operational capacity through new or upgraded substations, transmission, and distribution systems nationwide. Our professionals work as an extension of your team for planning and development, land acquisition, right of way (ROW), permitting, electrical engineering, and construction management. Our full-service program management and in-house EPC capabilities make the most of capital investments with seamless coordination of every phase and discipline. As a trusted partner in the industry, we work with you to align project outcomes with your overall goals.


Atwell’s distribution design and engineering team understands that owning and maintaining a local distribution system is unique when compared to other large energy projects. We approach each utility with intent on learning every nuance, preference, and process specific to that client to be successful. We understand that safety and the utility’s customer satisfaction are paramount, and we share those same priorities with how we approach every project. Our electrical distribution services team has the knowledge to solve your challenges, with extensive experience in a variety of project delivery methods. We can assist with specific engineering components or perform full turnkey engineer-procure-construct (EPC) projects. Whether you need to bring a new system online, relocate facilities, inspect and inventory distribution assets, manage pole attachments and make-ready, or assess and recover from storm damage, our team has the experience you need to be successful. By understanding the need for current and future load demands on the system, you can better allocate resources and investments to implement upgrades and expansions to the grid. We help identify critical areas for improvement, set priorities to maximize impacts to the system, and implement solutions through design and construction.
