According to the International Renewable Energy Agency (IRENA) the expansion was fueled […]

The traditional electricity grid is being transformed, as more businesses look to control their costs by producing their own power. A need for reliable backup power, the push for more resiliency in generation

Nevada law has included net metering provisions for more than 20 years. Net metering is an arrangement that allows energy generated by a customer’s leased or purchased solar system to offset monthly power bills. It also permits excess energy supplied to the grid to earn credits, which are then automatically applied to future billing periods […]

More and more people are finding distributed energy solutions are the answer for their power resource challenges. Distributed energy comes in many forms. Renewables such as solar and wind are top-of-mind when most people think of distributed resources, but natural gas-fired generation is often a good fit too, because it adds reliability to the system […]

After decades of lethargic power demand—and negative growth in 2017—U.S. electricity use is expected to grow steadily through 2050, driven by a healthy economy and increasing efficiency, the U.S. Energy Information Administration (EIA) projects in its Annual Electricity Outlook 2018 (AEO2018). However, during that period, direct-use generation will outpace growth in retail sales as more […]

American Electric Power (AEP), one of the nation’s largest power generators, will pursue a strategy to reduce its carbon dioxide (CO2) emissions by 60% from 2000 levels by 2030, and 80% from 2000 levels by 2050. AEP expects to achieve carbon reductions through a variety of actions, including investments in renewable generation and advanced technologies […]

The rapid growth of distributed energy resources (DERs) is spawning new financing models that could send growth for the fledgling sector soaring, upending the power sector at an even more breakneck pace. Industry executives at Distributech 2018 in San Antonio, Texas, this week noted that several trends are driving the growth of DERs, which are […]

Siemens has launched a new direct-current (DC) transmission system for alternating current (AC) grids of between 30 kV and 150 kV. The medium-voltage system that can bridge distances of up to 125 miles is designed to help grid entities handle ever-growing volumes of power fed into the distribution system from distributed and renewable power. The […]

It’s often said that technology runs well ahead of the law. Not so long ago, the process of setting electric utility rates was only slightly more dramatic than watching paint dry. This was by design. There was generally only one goal—keeping the lights on—and everything else was structured to support it. The utility generated the […]

Executives from power companies operating in different markets revealed how their firms are being affected by low natural gas prices, pressures to achieve fuel diversity, distributed energy generation, and lax demand growth, among a number of topics. The annual executive roundtable panel at the ELECTRIC POWER Conference and Exhibition on April 19 was moderated by […]

Distributed generation (DG) is receiving much attention as a resource that can facilitate the development of a smarter, more resilient, and more sustainable electric grid. Several jurisdictions, including New

Distributed energy firm Vivint Solar has terminated an agreement under which it would have merged with renewables giant SunEdison in a $2.2 billion deal. The Lehi, Utah–based company told investors on March 8 that it had delivered a letter notifying SunEdison that the merger agreement had been terminated, owing to SunEdison’s “failure to meet obligations” […]

In large part because of swelling supplies of natural gas, and failing crude oil prices that have helped depress gas prices around the world, as well as because of its environmental advantage over fuel oil, liquefied natural gas (LNG) is garnering growing interest as a generation fuel. While huge, multi-billion-dollar LNG import and export terminals […]

New energy technologies, decreasing renewable energy costs, and low natural gas prices are forcing changes in the way traditional power companies must plan for the future. “A fundamental rethink is now well underway about how energy gets produced, delivered, consumed, and managed in many parts of the world, including the U.S.,” said Ethan Zindler, head […]

North America’s reserve margins are trending downward, even though electricity demand has generally fallen, the North American Electric Reliability Corp. (NERC) warned in a new report. The international regulatory authority established to gauge and improve the reliability of North America’s bulk power system (BPS) said in its annual long-term report that electricity demand has dropped […]

Battery energy storage has exploded in deployment over the past several years, but the majority of it by capacity, especially in North America, is deployed at grid scale. That may be a problem, because a new study from the Rocky Mountain Institute (RMI) suggests the greatest value to the system lies with behind-the-meter batteries—distributing battery […]

If you’re looking to generate distributed power with gas, your options are broader than ever, with a range of efficient, clean-burning technologies to chose from. Knowing which option is the right one depends on a balance of site constraints, fuel supplies, and environmental oversight. When California State University San Marcos (CSUSM), a 14,000-student university north […]

NRG Energy has embarked on a “reset” that will see a separation of its core distributed generation and fossil fuel businesses.  The company, headquartered in Princeton, N.J., wants to “simplify” NRG Group to cut down expenses and debt. In a transition that will begin now and be fully effective on Jan. 1, 2016, it will separate […]

The Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP) is feasible in its ultimate goals, but getting there will take a lot of work and some rethinking of how the targets are achieved

A new bill unveiled on May 6 by Sen. Angus King (I-Maine) champions a general right to neutrality of the interconnection of distributed energy resources (DER) and seeks to establish a set of national parameters for how DERs are governed. The day 30 on clomid no period Free Market Energy Act of 2015 would amend […]

As I write this column at the beginning of spring, I have two kinds of spring fever: excitement about warming temperatures that bring spring flowers and the “hay fever” caused by tree pollens. I have mixed feelings about spring. I mention this only because the power industry is experiencing a spring fever of its own. […]

Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase. The U.S. utility industry is […]

Speaking to a sparsely filled room as the last of four presenters during the keynote plenary session at the Energy, Utility & Environment Conference in San Diego, Calif., Feb. 16, Len Hering, executive director of the California Center for Sustainable Energy (CSE), made it clear that he doesn’t think natural gas is the answer to […]
