A 72 MW/72 MWH battery system owned by a global independent power producer is expected to soon start providing grid services in PJM territory, signaling the storage industry’s increasing maturation and ability to compete with traditional resources. Industry supporters have argued that getting more storage online to support renewables … [Read more...]
The unknown unknowns are what keep regional grid operators up at night. And right now the rapid growth of customer-sited microgrids, invisible to grid operators, count high among them. That’s the message delivered last week by Jonathan Monken, PJM senior director, speaking on a plenary panel at the Virginia Clean Energy Summit in … [Read more...]
NRDC's Tom Rutigliano refutes the argument by PJM that batteries must be able to run for 10 hours to replace a generator. "It’s as if the oil industry made a rule that electric cars weren’t allowed on the road until they have the same range on batteries as gas powered cars," he explains. Consider for a moment why hybrid cars are so efficient: … [Read more...]
The PJM Interconnection has begun a process to explore the role of utility connected microgrids in the organization’s wholesale power market. The process “is part of a general effort to make sure PJM rules can accommodate all types of cases and resources and make sure there is nothing that prohibits incorporating microgrids,” Andrew Levitt, … [Read more...]
Scale Microgrid Solutions is on a mission to make sophisticated microgrids as easy to deploy and finance as rooftop solar, said Timothy Hade, microgrid specialist for the company. “Our thesis is that at scale, microgrids have all sorts of great technical aspects that can make our total energy system cleaner, cheaper and more reliable. But … [Read more...]
The PJM Interconnection has made a temporary change in the rules for its frequency regulation market that could mean lower revenue and market participation for energy storage. The proposed rule -- which still requires approval by federal regulators -- addresses price spikes, or "price excursions," observed by PJM staff. Reinstates floor … [Read more...]
What solar installer hasn’t seen a homeowner’s face drop upon learning that rooftop solar panels don’t spare the home from an outage when the electric grid goes down? “I’ve invested in solar. I’m really excited because I’ve declared myself as independent from the power grid. I feel good because I’m a green citizen. Until I realize that as soon … [Read more...]
S&C Electric Company is serving PJM's ancillary services market with a 150-kW energy storage system located at its global headquarters in Chicago. The PureWave Community Energy Storage (CES) system will provide fast-response frequency regulation. As S&C pointed out in its news release this week, frequency regulation minimizes the … [Read more...]
What role can microgrids play when there is a Public Safety Power Shutoff (PSPS) in California? In this Q&A with Microgrid Knowledge, Ameresco’s Bob Georgeoff explores how quickly microgrids can be installed and their costs and benefits.
Leaders in large corporations, government agencies, and other organizations face numerous challenges in running their day-to-day operations. For them, energy – the lifeblood of many organizations – has historically been seen as reliable, and occasional power outages considered an inevitable cost of doing business. However, these same organizations are starting to view energy and the associated risks and opportunities in a new light as power outages continue to impact their organizations and as new energy innovations make it to market. Download this new white paper from Ameresco that explores ways in which government agencies, companies, and other organizations can leverage their energy infrastructure to minimize the adverse impacts of major events – in other words, become more resilient.
