Hawaii to Test Smart Water Heaters as Grid Resources

November 22, 2014 by Jeff St. John

Hawaii and Smart Water Heaters

Hawaiian Electric is trying out all sorts of distributed energy assets to help it manage its solar-impacted island electricity system, including behind-the-meter batteries, and smart-meter-enabled energy disaggregation. But one of the cheaper grid tools at its disposal could be the ubiquitous electric water heater.[read more]

Two Years After Sandy, the Conversation Around Energy Resiliency Still Going Strong

November 22, 2014 by EDF Energy Exchange

Disaster Preparedness and Resiliency

New Jersey has made great strides forward and impressive progress toward making the Garden State’s energy infrastructure more resilient in the two years since the damage and flooding from Superstorm Sandy caused a massive weeks-long power outage.[read more]

What Does New York's 'Energy Vision' Mean for Utility Jurisdiction and Regulators? [VIDEO]

New York's Energy Vision

Before the New York Public Service Commission’s vision of a grid operated by Distributed System Platform Providers (DSPPs) can become a reality, there are just a few points to hammer out -- to say the least. The issues are complex and wide open for debate.[read more]

Three Global Utility Metatrends

November 19, 2014 by Christine Hertzog

European Utility Week serves as an excellent venue to obtain more global industry perspectives than what is typically found in most industry events. In the case of the 2014 event, it served to reinforce the conclusion that there are really three global metatrends in play for electric utilities.[read more]

Homeland Security: Russian Hackers Infiltrated US Energy Infrastructure

Energy Infrastructure Risks

The U.S. Department of Homeland Security issued an updated alert last week stating that a variant of the BlackEnergy malware had infiltrated the SCADA systems that control critical infrastructure, including oil and gas pipelines, water distribution systems and the power grid.[read more]

What Is a Smart Home? Most People Don't Know

November 12, 2014 by Katherine Tweed

The Smart Home

 

Two-thirds of U.S. consumers with broadband are not very familiar with smart home services or products or where to buy them, according to a new survey. That will likely change quickly in coming years, but for now, it’s not just an open market, but also a nebulous one.[read more]

Buildings, Renewables, and Grid Integration

Grid operators may have a new ally in their efforts to integrate renewables and regulate the frequency of the grid: buildings. Variable-speed drives used to run heating and cooling systems can be modulated in response to signals from grid operators, helping keep the frequency of electricity flowing across the grid.[read more]

Cost-Benefits Analysis of Utility-Scale Energy Storage is Promising

Utility-Scale Storage Analysis

I recently read a white paper by Chet Lyons of the Energy Strategies Group performing a cost-benefits analysis of utility companies purchasing battery storage systems vs. simple cycle gas-fired combustion turbines (CT). These CT systems are typically used to regulate peaking capacity.[read more]

Want Green Power? Try Community Choice Aggregation

October 29, 2014 by Christine Hertzog

Community Choice Aggregation (CCA) or municipal aggregation, is defined as an energy policy that can promote distributed and/or renewables generation through community-based contracts with electricity suppliers. The community acts as an aggregator, and residents within it are automatically part of that CCA.[read more]

If You Could Build a Solar-Friendly Grid From Scratch, How Would You Do it?

The 20th-century electrical grid is a truly extraordinary feat of engineering and construction that has been a core driver of economic progress in many developed countries. But it's finally starting to show its limitations as we move into the 21st century.[read more]

In the Wake of Court Ruling, What’s the Future of Demand Response?

Demand Response Court Ruling Effects

On September 17th, the D.C. Circuit Court of Appeals declined en banc review of Federal Energy Regulatory Commission Order 745, dealing a blow to FERC’s regulation on demand response. So we’re likely about to see an unnecessary rise in electricity prices and increase in new polluting power plants.[read more]

SolarCity, Nest to Energy Regulators: Open the Grid

Rooftop solar, behind-the-meter batteries, smart thermostats, home automation. All are sources of energy, capacity, and reliability for the power grid. So say the engineers who’ve built them -- and so say the customers buying them. Now if only the regulators would move as fast as the engineers and customers.[read more]

Grid Modernization and Public Lands

During my career I have worked as an advocate for protecting wild places and creatures as well as a proponent of sustainable energy development. While there has seldom been conflict between these two goals, the overshadowing issue of global climate change has forced them together in unexpected ways.[read more]

University Microgrid Manages Multiple Generation Assets

October 21, 2014 by Christine Hertzog

Combined heat and power tech are sometimes overlooked as assets that can be deployed in Smart Grids and microgrids in North America. Also known as cogeneration, it is defined as the production of electricity and useful thermal energy from a single fuel source, typically located at the point of consumption.[read more]

How Microsynchrophasors Could Keep Solar-Saturated Grids Stable

October 19, 2014 by Jeff St. John

Solar Energy and Stable Grids

The electricity from rooftop solar PV is very different from conventional electricity. It sags and surges in response to the pattern of clouds crossing overhead, and is also provided by lots of inverters, which create electrical conditions very different from the alternating current supplied by big spinning generators.[read more]
