Renewable Solutions Expertise

A Sustainable Solution for the Future

Complete Designs for Your Renewable Solution

The science and business of effectively capturing, storing, and utilizing sources of renewable energy have come a long way and continue to shift. As renewable energy options become increasingly accessible and profitable, more and more companies are recognizing the value and impact that comes with expanding their renewables portfolio. Across the spectrum, businesses and consumers are embracing alternative energy solutions.

Renewable energy is here to stay. Around the world, communities and organizations have lofty goals to reduce or completely offset their carbon impact, and they’re setting their sights on renewable energy resources to hit those targets. Whether your generator is a solar module, wind turbine, or battery, NEI has the expertise to design the project matching your requirements, providing seamless integration from end to end.

As this new era in energy unfolds, adhering to tight schedules and increasingly complex automation and control reporting are more important than ever. Ensuring that all necessary power is properly networked and set up with state-of-the-art automation controls requires detailed knowledge of both electrical and control system engineering principles and hands-on experience. We make it easier than ever to get critical real-time reporting to ensure every stakeholder has what they need, right when they need it.


We are equipped to meet the challenging time and cost constraints inherent to many renewable energy projects, all while delivering high-quality designs. From concept through design and implementation, our solutions are developed with ease of constructability in mind, and we understand the importance of consistent design for long-term maintenance and operations.


We bring custom ideas and solutions to the table and can support them from concept through design, construction, and implementation. Our industry experience and ingenuity allow us to be responsive and flexible in adapting to changing requirements.


NEI has been designing and field commissioning renewable energy solutions since the early 1980s. As renewables accelerate, we have the best teams in the industry supporting everything from concept development to complete design creating less unpredictability when it comes to budget and schedule. We have a team that has powered the industry since the beginning. 


Today, solar providers are asked to do more with less. Facing tight budgets and strict oversight, NEI understands that the solar power environment is constantly in flux. When we work with our clients for solar design and electric power distribution needs, we bring years of experience and insight to every project. From interconnection and relaying design to substation design and commissioning, NEI has the experience and dedication you need to ensure a successful solar project.

As the solar industry continues to grow so does competition. With more providers entering the market, ensuring projects are completed on time, on budget, and in a way that is safe and maintainable, is paramount. Our decades of work in solar power generation and distribution gives us a unique perspective on the planning and commissioning of solar projects.

Your Partner in Wind.

Planning, designing, and commissioning small-to-large scale wind projects takes foresight, experience, and pinpoint planning. When you partner with NEI Electric Power Engineering for your wind development project, you’re gaining a team of experienced engineers who can assist you in everything from preliminary research and feasibility studies to completely integrated SCADA and high voltage infrastructure.

For decades, clients have successfully navigated a competitive and price-sensitive industry with the help of NEI’s multi-disciplinary team. Our team of engineering experts and project managers have in-depth knowledge of utility and developer standards ensuring that together with our clients, we can deliver a successful wind farm meeting all project needs. 

Our depth of expertise and experience has helped clients bring powerful wind solutions to their customers and their communities. When deadlines are tight and budgets are thin, NEI works as an extension of your team in the field ensuring that every aspect of your wind project is thoroughly planned and executed to the highest standards.

Wind Repowering

Wind repowering is setting the stage for the renewable energy transition by modernizing existing wind power plants to maximize energy efficiencies and production. By updating sites with new or refurbished technology, wind turbines can increase energy output and lead to cost savings using existing grid connections and infrastructure.

NEI’s experience working with utility and developer standards to bring quality and reliable designs ensures high production and efficiencies to any wind repower project. Our team of engineers helps clients evaluate the right elements to get the best solution possible for high efficiencies and maximum output.

This approach streamlines project deliverables and helps anticipate the next steps. The result is a seamless, end-to-end experience with a reliable, maintainable solution.

For years, NEI Electric Power Engineering has been the go-to partner for energy storage facilities looking for an intelligent, thoughtful approach to design, commissioning, control integration, and startup. Our comprehensive energy storage solutions help clients balance power loads, regulate generation over time, and provide ancillary services, including frequency regulation to help maintain grid stability. With experience doing both AC and DC coupled designs, our experts can provide the right solutions for each project.

Every day a project is offline is a day without revenue. Battery energy storage projects need to move fast so profitability can happen as soon as possible. Our multidisciplinary team of experts has helped clients deliver renewable power to the grid. With the acceleration of renewable generation and energy storage, the future is bright.


Thousands of communities rely on local hydroelectric plants for clean, reliable power. Demand for cleaner energy sources—and an increase in the pressures placed upon existing facilities—is at an all-time high, with little chance of slowing down. Since the early 1980s, NEI Electric Power Engineering has been supporting the hydro community with everything from design, planning, commissioning, and retrofitting hydro facilities.  We implement SCADA and distributed control system (DCS) solutions from the outset, so when it is time to flip the switch, your comprehensive solution is ready.

Hydroelectric power is among the oldest reliable power sources, and we have a long history of working on retrofit programs for aging hydro and pumped storage facilities. Upgrading and commissioning older hydroelectric plants requires a clear understanding of older infrastructure and practices, as well as a creative eye for retrofitting and power distribution. NEI has worked with hydroelectric partners across the world modernizing their facilities and bringing safe, reliable power to new, state-of-the-art hydroelectric plants.
