Are dry type transformers really cost less?

Comparison to dry type transformers To many industrial and commercial organisations dry type transformers are seen to be advantageous compared with oil filled units. They avoid the perceived fire risk of oil filled transformers and can thus be accommodated inside a building or even on the roof of an office block. Savings can be made […]

Underground residential distribution – More hidden and more reliable

Underground residential distribution / URD A classic underground residential distribution circuit is an underground circuit in a loop arrangement fed at each end from an overhead circuit (see Figure 1). The loop arrangement allows utilities to restore customers more quickly. After crews find the faulted section, they can reconfigure the loop and isolate any failed […]

CT DEEP Launches RFP, Includes Some Provisions for Energy Storage

The CT Department of Energy & Environmental Protection (DEEP) has launched an RFP for 2-20MW’s renewable, passive demand response and energy storage procurement. 

ESA on the Ground in MA

The Energy Storage Association is leading a collection of New England companies in advocating for S. 1762 today in the Massachusetts State House. The ESA also delivered a letter today to State House leaders signed by more than 20 storage and clean tech companies and organizations calling for the inclusion of S. 1762 in an upcoming omnibus energy bill in MA. 

SDG&E Seeks Energy Storage, Renewable and Other Clean Energy Resources

SAN DIEGO, March 7, 2016 -- San Diego Gas & Electric (SDG&E) announced it is seeking up to 140 megawatts (MW), of new "preferred energy resources," including energy storage, renewable energy, distributed generation, energy efficiency and demand response. The solicitation for additional preferred energy resources builds upon SDG&E's significant investments in clean energy. The utility currently has more than 60 renewable contracts representing more than 2,400 MW of renewable energy, the equivalent of powering more than 700,000 San Diego homes for a year. In 2015, SDG&E became the first California utility to supply its customers with a third of its energy, 33 percent, from renewable resources. "We're not only committed to reducing air emissions and meeting California's climate goals, we're leading the way," said SDG&E's Chief Energy Supply Officer, Scott Drury. "Through renewable energy investments, we've helped to advance clean energy technologies resulting in emissions reductions that are comparable to taking more than 250,000 gasoline-powered cars off local roadways."

The grounding electrode conductor The grounding connections The grounding electrode Electrode to soil resistance The soil 1. The grounding electrode conductor Typically made from copper or copper-bonded […]

Energy Storage Association and USTDA to Host International Trade Delegations at 26th Annual Conference and Expo

Washington, D.C. – March 8, 2016 - The Energy Storage Association (ESA) and the U.S. Trade and Development Agency (USTDA) will host multiple international delegations through a Reverse Trade Mission to meet with U.S. manufacturers and providers of energy storage solutions at the ESA 26th Annual Conference and Expo in Charlotte, NC, from April 25-27. 

The delegations include public sector officials and high-level corporate representatives from South Africa, Brazil, Colombia, India, the Philippines, Turkey, and Vietnam. These countries are planning to make significant investments in energy storage solutions in order to provide affordable, reliable power to consumers and to integrate renewable energy onto their grids. The delegates seek to implement energy storage projects, purchase energy storage solutions and learn more about financing mechanisms and policies that support energy storage deployment.
