Eaton has a fully integrated and flexible Hybrid Solar dc power package which provides users with a mission critical remote and renewable power system. Compliant with international standards, the new Eaton ASC48–ES solar harger is designed for communications network operators who aim to cut energy costs or are required to meet aggressive carbon footprint reduction targets. The hybrid solar dc power solution uses Eaton’s range of modular power building blocks and power chassis. Key features include a high-performance maximum power point tracking function which can extract the maximum possible power from the solar panels. In addition, the solar charger features intelligent digital signal processing for enhanced control, producing peak efficiency in excess of 96% for typical operating loads, while also maintaining a very high minimum operating efficiency of 95 to 96%, over a wide range of loads (from 30% to 100% of the 2kW capacity).

Too lazy to turn on and off the switch ?
How about smart light bulbs? GE has revealed a brand-new LED light bulb that can connect to the Web shortly after you’ve twisted it into an available socket. Dubbed the Link, the $15 light bulb will be controllable by a companion appn for iOS and Android ~ “Wink.” If that sounds familiar, it will be the same app used to control other appliances once the accompanying $79 Wink Hub goes on sale on July 7, thanks to a collaboration between GE and New York-based startup Quirky, which also helped produce the Link light bulb (and partnered with GE on a smart A/C, too). The Link won’t need a Wink Hub to work; you’ll be able to flip it on and off using the Wink app, which GE describes as a benefit for those who want a little more control over their home setup while they’re away from home (say, at work), those who want a bit more security when they’re away from their homes (while on vacation), or those who are otherwise too lazy to get up and hit the lights while on the couch.

Offshore wind too expensive
On: Topic: General

Britain should stop building expensive offshore wind farms, energy giant Centrica has said. Reported in the UK Daily Telegraph the company claims billpayers could be saved £96bln by 2030 if ministers pursued a cheaper green strategy.

The British Gas owner ~ whose chief executive Sam Laidlaw is preparing to step down after eight years ~ on Wednesday took the unusual step of issuing its own manifesto for how to solve Britain’s energy crisis, claiming its plans were three times cheaper than Government’s.

The report, which points the finger of blame at Government for backing expensive green technologies, offers a “more affordable pathway to a lower-carbon future”, Mr Laidlaw said.

It advocates building no more offshore wind farms, which it calls “an expensive option that may not be needed”, stopping solar panel deployment, “since it generates no output at times of peak demand” and restricting use of expensive solid wall insulation for homes.

Instead it backs gas, nuclear and carbon capture and storage (CCS) plants.

It claims the plan would save consumers £100 a year by 2030, compared with the Government’s strategy, while still hitting 2050 carbon targets.

One Whitehall source dismissed the report, saying: “Centrica ignores legally binding targets that are not going to go away.”

California’s solar energy output is setting records but renewables still represent a small share of the state’s power generation, the Energy Department said. The Energy Information Administration, (EIA) the statistical arm of the Energy Department, said during peak daylight hours, solar power supplied 14% of the electricity for the California Independent System Operator, which oversees the state’s grid. EIA noted during peak daylight hours, solar power offsets the use of natural gas or interstate electricity imports. During lulls, however, the share of other fuel sources increases. “Solar and renewables still constitute a relatively small share of generation for California in the context of all fuel sources,” EIA said in a Wednesday (26/6/2014) briefing. “Natural gas accounted for 59% of net generation in 2013, and 3940MW of new natural gas capacity came online in 2013.” The grid operator posted a midday record of 4767MW from solar power June 1. The May average of 4086MW was 150% higher than May 2013. California in 2013 accounted for more than 75% of the nation’s solar output. — UPI

The Alberta Electric System Operator and BC Hydro are to work together to restore transfer capacity on the British Columbia-Alberta intertie, which operates at levels well below its rated capacity. Alberta can import about 700MW to 800MW from British Columbia and Montana, according to Angela Anderson, a spokeswoman for the AESO. The grid operator expects to increase its overall import capability to 1500MW, with most of the work being finished in the 2018 to 2020 timeframe, she said. The BC-Alberta intertie is rated at 1200MW for importing into Alberta and 1000MW for exports. However, for various reasons, including a new transmission link with Montana, it usually imports between 400MW and 500MW range, according to Anderson.

Naturdünger Münsterland (NDM) and RWE Innogy have canned a new biogas plant at Velen, Germany. The reason is the reform of the German Renewable Energy Act (EEG) which makes the project uneconomical. The following amendments to the EEG have a significant impact on large biogas projects in Germany and also make the planned plant in Velen uneconomical: major reduction of remuneration rates for biogas; deletion of the input material remuneration categories, also for agricultural residues and the deletion of the gas processing bonus without replacement. Since the new EEG also prevents the likelihood of similar projects in the future, RWE Innogy and WLV are also ending their collaboration. RWE Innogy and Naturdünger Münsterland GmbH & Co. KG intended to build a 4.2MW biogas plant at Velen. Input materials: 90% of manure solids extracted from about 700,000 cubic meters of untreated manure and 10% of catch crops. Apart from processing and feeding the biogas into the natural gas grid, the innovative plant concept allowed for complete processing of the fermentation residues with fertiliser recovery, which would have offered a solution to the growing nutrient surplus in the region.
