From waves to wood chips to grass, the renewable energy era has been all about generating power from unlikely sources. A Washington, D.C., utility has taken this trend one step further and is harnessing power from sewage effluent.
With cities and utilities worldwide upgrading to light-emitting diode (LED) lighting for streets and outdoor areas, owners and installers wonder when they will build in the controls for smart-city applications.
Nevada’s Public Utility Commission has made it increasingly difficult for the state’s solar-power market, pushing out at least three solar companies. In January, the commission voted unanimously against requests to delay the implementation of controversial changes to metering rates.
Innovative programs in the energy sector need all the help they can get. Vested interests, such as utilities and power providers, have a profit motive for maintaining the status quo. Sometimes, government is the only hope. Other times, it stands in the way.
As controversies continue over the growth of residential solar-power installations and the various policies that support them, one state is standing by its program. In doing so, it has set an example for how to strike a balance between the needs of customers and utilities.
On Wednesday, Mar. 23, the District of Columbia Public Service Commission voted two to one to approve a $6.8 billion merger between Pepco Holdings and Exelon, creating the largest investor-owned utility in the nation. Combined, the two utilities will now serve 10 million customers.
As the power sector evolves to accommodate innovations such as renewables and efficiency, utilities and providers have not always embraced change.
However, conservation proponents won a national battle recently, when the U.S. Supreme Court upheld a regulation supporting demand-response programs.
The results of a new survey of 500 energy industry representatives (utility executives, regulators, distributed energy providers, etc.), conducted by GTM Squared, a research arm of Greentech Media, suggest that ongoing regulatory proceedings designed to properly value distributed energy resources (D
In January 2014, a weather front known as a “polar vortex” descended from Canada’s arctic north and brought frigid temperatures and heavy snow and ice as far south as Texas and eastward to the Mid-Atlantic and New England.
As our energy mix changes, the need to improve the infrastructure for delivering that power also grows. Utilities recognize that need and are investing in upgrades to their delivery systems. Customers in New York and Pennsylvania are about to benefit from one such upgrade.
Plans have been made to close 2,000-plus megawatts (MW) of U.S. nuclear generating capacity in the next four years, but that will hardly have a negative effect on the country’s capacity as a whole. In fact, the U.S.
The electrical energy usage in most industrial and commercial facilities follows a reasonably consistent pattern from week to week, so a one-week monitoring program usually is adequate to determine what can be done to save 10–20 percent on electric bills.
Utility companies have driven smart-meter installation in homes. Now, touting the amount of useful data smart meters can provide, utilities and building owners are setting their sights on commercial and industrial buildings through submetering.
Energy storage is indispensable to renewable power’s success. Increasingly, it is also becoming a prominent feature in the appeal of electric vehicles. Storage works at the wholesale and retail levels by facilitating grid stabilization and home energy management.
Solar power continues to suffer from the obstacle of high upfront costs. Although the electricity it generates is free, that is still not enough to make up for the hefty cost of purchasing and installing the equipment for many consumers.
Residential demand-side management (DSM) programs aren’t a new concept. As far back as the 1970s energy crisis, electric utilities had programs enabling separate rates for customers’ water heaters (which was then a typical home’s biggest energy user).
