Distributed Energy

The “polar vortex” storm of January 2014 blew in big changes to PJM Interconnection’s operations. But these changes are now the subject of a lawsuit filed by environmental groups, alleging they discriminate against clean energy sources. The sub-zero temperatures froze coal piles and gearboxes. Natural gas plants, lacking firm contracts for fuel delivery, were unable […]

Although it’s not widely publicized, a majority of the energy used to generate electricity is wasted in the form of heat discharged to the environment. For better or worse, that’s just the way a typical thermal power plant works. Fuel, such as coal, biomass, natural gas, or uranium (in the case of nuclear plants), is […]

Enrico Viale, head of global thermal generation for the Italian energy company Enel, kicked off an international power industry event yesterday with a keynote presentation describing the “needs” of utilities in the future.

Panels at the 2016 Edison Electric Institute convention focused on technologies and policies at what’s often called the “grid edge.”

  Even though it may dominate forecasts, natural gas–fired generation faces a troubled expansion in the U.S., according to experts from a variety of stake-holding entities—including an industry group, a utility, a generator, and a pipeline company. Challenges that have few solutions—from price volatility, to gas transport concerns, to rule uncertainty—may upend the nation’s dependence […]

The annual panel discussion by high-level leaders from diverse power companies is a cornerstone of the ELECTRIC POWER Conference & Exhibition, and it has been consistently emblematic of the state of the

Fuel cells powered by natural gas, biogas, and hydrogen are a rapidly expanding option for distributed generation, with fuel cell­­–based power plants being deployed in capacities into tens of megawatts. But as the technology improves and costs begin to scale, opportunities for other applications are being explored. One such application may even go beyond power […]

Hands down, 2015 was a record year for global investment in renewable energy. Excluding large hydroelectric projects, the amount of money committed to renewables rose 5%, to $285.9 billion, exceeding the previous record of $278.5 billion reached in 2011.

It’s not being overly dramatic to say that the power industry is at its biggest inflection point to date. Even ignoring the effects of environmental regulations and (in North America, at least) cheap natural

States across the U.S. have begun to commit themselves to expanding the reach of distributed energy resources (DERs), primarily rooftop solar photovoltaics (PV), throughout their communities. In particular
