Energy Storage Is Essential for Grid Efficiency

Utilities have always strived to balance electricity production with demand using traditional generation. Primary sources are coal and nuclear power plants along with natural gas turbines, including the inefficient and costly “peaker” plants that are used only during periods of unusually high demand, typically a few dozen hours per year. To help make the grid [...]

The Year in Solar Energy: What We’ve Gained

Solar has become an essential source of new electricity generation in the U.S. During the first half of 2014, solar comprised more than 50% of all new electricity generation capacity, according to reports by the Solar Energy Industries Association (SEIA) and GTM Research. That number will continue to climb, fueled largely by growth spanning solar-progressive [...]

Planning for More Renewables? We Need to Plan for More Energy Storage, Too

You likely heard the biggest news in our industry last week—namely, that the U.S. Environmental Protection Agency has proposed new rules to reduce greenhouse gas emissions from power plants. Under the proposed rules, states would have some choice in how they meet the proposed rules. But it seems certain that renewables will be a big [...]

Trying to Solve Power System Challenges? See New Solutions at the IEEE PES T&D Show

The power system faces major challenges today. Extreme weather is one issue, as many of parts of the U.S. have seen this winter. From frigid temperatures that caused spikes in peak demand, to snowstorms that caused power outages, to a historic drought in the West, power systems have taken a beating this year. New technologies [...]

Microgrids: Threat or Opportunity for Utilities?

Microgrids are not just mere hype. They are indeed gaining traction globally, as more electricity customers—particularly businesses that comprise a large percentage of utility revenues—look for new alternatives to reduce costs and increase reliability. In Germany—which is currently undergoing an expensive program to phase out nuclear electricity generation while also integrating more wind and solar [...]

Making Renewables Convenient for Consumers

Recently, I was interested to see a survey showing that consumers value clean energy above reliability. Though I firmly believe that clean energy will play an essential role in our energy future, I worry that such survey results confuse the issue on how consumers value reliability. There may be some consumers who do not want [...]
