Microgrids begin to make economic sense.
Technology is changing the game. Is your utility ready?
Although today microgrids serve a tiny fraction of the market, that share will grow as costs fall. Utilities can benefit if they plan ahead.
A challenging year brings a change in the rankings.
(July 2012) Thanks for your enlightening editorial about the problems of feed-in tariffs for photovoltaic installations and the distortions they are causing in cost responsibilities among electric utility customers. While these issues are an immediate and growing concern, an entirely different set of problems will emerge over the next decade as the share of renewables in total generation approaches the high levels being dictated by most regulatory authorities.
Utilities sound the alarm as PV nears grid parity.
A growing wave of rooftop PV projects is starting to look ominous to some utilities. Will lawmakers accept utilities’ warnings at face value—or will they suspect they’re crying wolf?
Manufacturers scale up for utility applications.
Photovoltaics technology is emerging as a generation alternative—both for centralized and distributed facilities. Solar industry executives say their companies are overcoming obstacles to large-scale implementation. With advances in design and manufacturing, the future looks bright for utility-scale solar power.
Effective metrics give solar its due credit.
Photovoltaic (PV) power generation is an intermittent, non-dispatchable resource generally considered as energy-only with no capacity credit. However, there is ample evidence that solar energy reliably is available at peak demand time when loads are driven by day-time commercial air conditioning, and can contribute effectively to increasing the capacity available on a regional grid.
Green Generation Feels the Squeeze
Chasing after windmills and photovoltaics could well be the stuff of fiction.
Wind and solar cells (photovoltaics or PVs) are two renewable energy technologies that many hope will eventually provide the United States with massive amounts of clean, sustainable electric power for the indefinite future. Indeed, it is often suggested or implied that the United States can look to a future where most, if not all electric power can be provided by wind and photovoltaics [1, 2].
