Energy Infrastructure on Tenuous Winning Streak in the Courts

Federal courts have been pretty kind to energy infrastructure in recent weeks, particularly in cases involving the National Environmental Policy Act (NEPA). For starters, this month, the U.S. Court of Appeals for the Ninth Circuit removed one of the hurdles to construction of the Keystone XL pipeline. The court decided that a new presidential permit—issued […]

Apagón: A Blackout Sweeps South America

Authorities have initiated a far-reaching investigation into an unprecedented blackout that on June 16 hit a wide swath of South America—most of Argentina and Uruguay, and parts of Paraguay—affecting tens of millions of people.  The massive blackout—apagón—is thought to have originated in a disturbance that affected two high-voltage lines, Colonia Elia Y Mercedes and Colonia […]

GE Launches New Analytics Technologies to Boost Grid Efficiency 

General Electric (GE) has rolled out a new portfolio of predictive analytics that could allow utilities to use data from transmission and distribution networks to achieve better operational efficiency as more distributed assets are introduced to the grid.  The company on June 11 unveiled three new grid analytics—for storm readiness, network connectivity, and effective inertia—that […]

How Residential Energy Storage Could Help Support the Power Grid

Household batteries could contribute to making the grid more cost effective, reliable, resilient, and safe—if retail battery providers, utilities, and regulators can resolve delicate commercial, operational, and policy issues. The growth of battery storage in the power sector has attracted a great deal of attention in the industry and media. Much of that attention focuses […]

Where Is the Microgrid Market Headed?

Increasingly, today’s electric power grids are interacting with microgrids and in more complex ways. Yet, much work needs to be done to integrate microgrids and flexible demand into the wide-area synchronous

Temperature Monitoring Protects Low-Voltage Assets

Early detection of increased temperatures helps avoid power distribution asset-related failures and unplanned shutdowns. Wireless technologies make implementing this predictive maintenance solution practical

MHPS, Magnum Will Build 1-GW Renewable Energy Storage Facility in Utah

Mitsubishi Hitachi Power Systems (MHPS) and Magnum Development, the owner of a large and geographically rare underground salt dome in Utah, have teamed to develop a massive project that could store up 1,000 MW of renewable energy year-round and provide it to variability-challenged Western power markets.  The companies this week signed a memorandum of understanding […]

Insights Into Siemens’ Stunning Gas and Power, Renewables Shakeup

In the days following its May 7 announcement that it will spin off its Gas and Power business, Siemens has fleshed out how and when the carveout will occur, laid out its reasons for lumping its energy businesses together, and put forth a market case for why a business separation may be a “win-win” situation […]

EMP Threat Real but Limited, EPRI Says in Much-Anticipated Report

Depending on the hazard field, electromagnetic pulses (EMPs) resulting from detonation of a nuclear weapon at high altitude or in space could cause significant damage to electronics on the bulk power system and even prompt a regional voltage collapse, the Electric Power Research Institute (EPRI) says in much-anticipated findings from its three-year study on high-altitude […]

Certifying Precision Timing in the Smart Grid

Utilities deploying precise timing in their networks have an additional choice in evaluating solutions based on whether or not the devices are IEEE certified for compliance to the appropriate IEEE 1588 Power Profile. To reach this point, years of effort from the IEEE, International Electrotechnical Commission (IEC), National Institute of Standards and Technology (NIST), and […]
