ERCOT’s Tight Reserve Margin and Renewable Energy: What’s it All Mean for Texas Businesses?

Texas

It’s been a hot summer in Texas, even into September, with the Electric Reliability Council of Texas (ERCOT) again last week urging customers to use less electricity. Given these events, and new renewable energy options, businesses in the state are — no doubt — thinking about their energy choices. Microgrid Knowledge will explore issues … [Read more...]

Researchers Propose Floating Microgrids Made up of Electric Boats

electric boats

Electric boats may enable floating microgrids that could serve islands that have historically been powered by fossil fuels, according to a report from researchers at the University of New South Wales in Sydney, Australia. “Powering small islands with reliable, affordable and green electricity is a big challenge due to their dispersed … [Read more...]

The Quick-Thinking, Self-Driving Energy Grid of the Future

autonomous energy grid

A quick-thinking, self-driving energy grid of the future — an autonomous energy grid — is being developed by researchers at the National Renewable Energy Laboratory (NREL). The goal is to integrate and make the best use of the many distributed energy resources (DERs) expected to come online in coming years, providing for fast-acting … [Read more...]

Massachusetts Close to Finalizing a Clean Peak Standard. Good News for Microgrids

local generation

Massachusetts is close to implementing a clean peak standard that could bring wider opportunities for microgrid developers. It would also make Massachusetts the first state in the nation to implement the standard. Based on the premise that renewable energy is good for the environment, but even better if used at the right time, the clean peak … [Read more...]

New York Launches Investigation into Electric Resource Adequacy

electric resource adequacy

New York has launched an investigation into its mechanism to ensure electric resource adequacy out of concern that its current approach fails to account for local reliability and environmental benefits. The Public Service Commission voted to initiate the proceeding (CASE 19-E-0530) Thursday and now seeks comments from interested … [Read more...]

Tough Summer for the Power Grid. But the Microgrids are Working

power outages

Severe heat and storms across the US this summer have strained the electric grid and caused extensive power outages. But the microgrids are working. Consider what happened on July 20 in northeast and north central Wisconsin when a thunderstorm knocked out power to 240,000 customers, leaving 50,000 with no power for two to three days. The … [Read more...]

History of Microgrids in the US: From Pearl Street to Plug-and-Play

history of microgrids

While it may seem that microgrids are new, the history of microgrids shows they have been around in some form for years in the US — although they haven’t always been called microgrids. The first one was introduced by Thomas Edison in 1882 at his Pearl Street Station, which combined heat and power and produced electricity and thermal … [Read more...]

Is Load Flexibility the New Demand Response?

load flexibility

Demand response is reaching a saturation point, but load flexibility is emerging as its new iteration, a 2.0 that is much more powerful and could become a 200 GW grid resource for the U.S. by 2030. That’s the word from the Brattle Group, in a report, “The National Potential for Load Flexibility: Value and Market Potential through 2030.” Among … [Read more...]

A Tool to Help Home Microgrids Stay Off Grid as Long as Possible

off grid

Researchers at the University of Texas San Antonio (UTSA) have developed an optimization tool for microgrids that allows homes to stay off grid as long as possible, generally using solar, storage and smart meters. The researchers recently received a patent from the US Patent and Trademark Office, based on a grant from the US Department of … [Read more...]

Taking Non-Wires Alternatives to a New Level, Company Petitions FERC to Move Electricity by Rail

non-wires alternatives

In a filing before the Federal Energy Regulatory Commission (FERC), Alternative Transmission (ATI) proposes a technology that could bring a new meaning to the concept of non-wires alternatives. Based in Sullivan’s Island, S.C., the company wants to move batteries by rail for discharge and charge where needed on the electric grid. Further, … [Read more...]
