Located on the border with Canada and operational since 1902, the Edison Sault Hydroelectric Plant is one of the oldest continuously operating power plants in North America. This pioneer plant continues to generate between 25 to 30 MW when operating at full capacity. Modern wind and solar projects have captured the public’s interest, but this century-old hydroelectric project shows that time is the ultimate arbiter of a technology’s value to society.

A £4.4 million grant by the UK’s Department of Energy and Climate Change (DECC) this September to Clipper Windpower’s Britannia project kicked up a whirlwind of interest in the supersized wind turbine—and others being developed around the world.

Sempra Generation has conjured up a market plan for producing merchant photovoltaic (PV) power that is inspired. Working with First Solar, Sempra has developed a finely tuned and standardized 1-MW PV power block that can be replicated as needed. Sempra built the modular PV plant on land adjacent to an existing gas-fired plant to shorten the development period, piggyback the power directly to the grid, and enable existing staff to manage the combined plants’ operation.

Anglo Coal, one of Australia’s coal mining companies this September opened a 45.6-MW power plant at its Moranbah North mine in northeast Queensland that captures methane-rich coal mine gas and uses it as a fuel to generate power instead of venting it into the air.

The tractors and combines on Indiana’s farms are getting some competition from a new harvesting technology — powerful turbines that harvest wind. This March the Fowler Ridge Wind Farm opened its first phase, which consists of 222 wind turbines with a total capacity of 400 MW. Phase II is currently under construction and will use 133 wind turbines with a total capacity of 200 MW. A future, third phase will add another 150 MW and give the completed facility a total capacity of 750 MW, which will make it one of the largest wind farms in the world.

Marine energy prototypes in the UK are sailing ahead of entries from the rest of the world, propelled by government backing and public support.

After decades of struggling with serious air contamination issues and large financial losses, this Pennsylvania waste-to-energy facility, which was built in 1972, was in need of an extreme makeover. In the wake of an unsuccessful $84 million retrofit attempt in 2005, the faltering facility’s last hope lay with a Covanta project team that took over its operation in 2007. After almost two years of hard work, the facility is now producing up to 17 MW while achieving its environmental compliance goals and earning substantial revenues.

This September, as Siemens Energy wrapped up testing of its H-class SGT5-8000H gas turbine at E.ON’s Irsching 4 gas power plant in Bavaria, Germany, the company raved about what it is calling "the world’s most powerful gas turbine."

By 2008, the 19-year-old wood-fired Rio Bravo Rocklin Power Station’s operating performance had been significantly degraded by boiler erosion and corrosion caused by (among many other problems) poor fuel. After much consideration, the plant owners elected to invest in a comprehensive upgrade to restore the plant to its as-built performance. Today, the plant operates very reliably. A newly implemented predictive maintenance program should continue to drive down operating costs and further reduce the number of forced outages.

A fiberglass-reinforced plastic (FRP) Halar stack liner was installed at Vattenfall’s 300-MW Unit 2 at the Nordjylland Power Station in 1995. The 112-meter-high (367-ft) stack, protected from corrosion by the ECTFE liner, is still in excellent condition and has not required any repairs during more than 13 years of service. (ECTFE is short for ethylene chlorotrifluoroethlyene polymer, marketed under the brand name Halar ECTFE [Halar] by Solvay Solexis.)
