Which Microgrid Controller Works Best Where?

microgrid controller

Which type of microgrid controller can take advantage of the largest amount of renewable energy? Which type of microgrid controller can wring the most money per MWh out of the microgrid? Which best ensures resiliency? Microgrid controllers can be optimized to focus on these and many other goals, but often can't be optimized to meet all these … [Read more...]

With Flexibility, Eastern Grid Can Get More than 30 Percent Renewables Online

With increased flexibility, the eastern grid can get more than 30 percent renewables online, and at times, can boost its renewables penetration to up to 60 percent. That's the word from a new report from the Department of Energy’s National Renewable Energy Laboratory (NREL), "The Eastern Renewable Generation Integration Study (ERGIS)." To bring … [Read more...]

How NREL Consumes 74% Less Energy Than National Average for Office Buildings

The National Renewable Energy Laboratory consumes 74% less energy than the national average for office space. NREL has a supercomputer, a plug-and-play megawatt smart grid and laboratories. The lab used state-of-the-art technologies to achieve the savings and took advantage of incentives from utility Xcel Energy. The total project cost of the … [Read more...]

!00% Renewables

If you're interested in following the latest research into microgrids -- especially 100 percent renewable microgrids -- keep an eye on the National Renewable Energy Laboratory in Golden, Col., which has a research microgrid. Among the microgrids under study are microgrids on islands, microgrids on military bases, and microgrids that are part of … [Read more...]

Underground Microgrids: Nothing to See Here Neighbors

utility microgrid services

Microgrids are good, underground microgrids are even better, especially in storm-prone regions. Buried wires are spared the destruction -- and outages -- brought by wind, snow and ice, which often topple over-head wires. Underground microgrids also escape the ire of neighbors who increasingly protest against stringed wire, especially in … [Read more...]

The Alcatraz Microgrid: Life on ‘The Rock’ Not Easy, Even for a Microgrid

The Alcatraz microgrid stands as a model for installing modern energy technology under difficult terms. Historical structures had to be kept intact, equipment protected from the elements, and no new buildings erected. Here's how developer Princeton Power  Systems accomplished the task. The 22-acre island in San Francisco Bay is now a tourist … [Read more...]

Uncovering the Energy Efficiency Insurance Risks of Small Office Buildings

Energi, a leading provider of specialized insurance and risk management solutions, and the National Renewable Energy Laboratory (NREL) partnered in October 2013 to analyze and begin to quantify the uninsurable risks of energy efficiency retrofits in small office buildings. Uninsurable risk is one of the largest barriers to financing energy … [Read more...]

Energy research and the cobbler’s children

By Elisa Wood November 5, 2009 Scientific research has brought us products that offer greater energy efficiency. But is research, itself, energy efficient? Evan Mills, staff scientist with the Lawrence Berkeley National Laboratory, raises this question and points out what may be a largely untapped market for energy efficiency companies: research … [Read more...]
