Energy Storage Is a Key Ingredient for All Microgrids

Recently I read where microgrids that generate half their power from solar supposedly don’t need energy storage. It might be true that they don’t need energy storage, but any microgrid developer that fails to include it in a photovoltaic (PV) project will miss out on a wide range of significant functional benefits that would help [...]

How a Smarter Grid Can Help Utilities Respond to an Existential Threat

Doomsday is approaching for electric utilities, according to many prognosticators. Though the term “doomsday” may be a touch strong, there is no doubt that new electricity generation technologies will pose real challenges to the established business models of power utilities in the coming years. The biggest threat, as has been well chronicled in both industry [...]

Preparing for Weather-Related Outages When You Can’t Predict the Weather

This week, Forbes reported that the National Oceanic and Atmospheric Administration‘s (NOAA) National Polar-orbiting Operational Environmental Satellite System is nearing the end of its lifespan—and when the system is decommissioned, NOAA will lose access to critical weather data for at least a year and a half. The gaps could begin as early as 2014 and [...]

Another Way for Power Grids to Beat the Heat? Think Asset Management

As the recent U.S. heat wave led to soaring electricity use—and in some places record-breaking peak demand—many businesses and consumers were asked to conserve power. Such conservation is necessary to reduce strain on the grid during a heat wave, as well as the risk of power outages. Grid operators met demand in the latest heat [...]

Three Solutions for Integrating Renewable Energy to the Grid

With Earth Day 2013 this week, we saw renewed focus on what actions should be taken to protect the planet against the effects of climate change. Not surprisingly, increasing global use of clean energy sources ranks high on the list. It’s a pressing goal for anyone who wants to reduce carbon emissions, particularly as worldwide [...]

Shaving Peak Residential Electricity Demand with Grid-Based Technology

Interesting fact, as reported by Katherine Tweed of Greentech Media: “when it comes to electricity hogs, the perpetrators are close to home and not at industrial sites and businesses.” Though a factory or a business uses more electricity than a single home, there is much greater variability in residential demand from season to season. As [...]
