Fujitsu cuts air con costs

Fujitsu Laboratories is enabling energy-saving operations of air-conditioning equipment in data centers. The company has developed highly accurate predictive technology for such metrics as temperature and humidity, which enables energy-saving by 20%. Air-conditioning equipment can account for between 30 and 50% of total electricity use. Fujitsu Laboratories' highly accurate prediction technology sequentially builds a model that predicts air-conditioning effects from collected data, enabling reductions in air conditioner energy use. This technology has enabled reductions in data center electricity consumption, contributing to global warming prevention. Existing data center air-conditioning equipment operates on the basis of information from a variety of installed sensors. This helps maintain the target temperature and humidity even when the operating rate of the ICT equipment it contains, such as servers, increases. When sensor data exceeds a set value, the system carries out rapid cooling for safety reasons, which causes air-conditioning to operate excessively. Although there are models available in the market that attempt to reduce energy saving at data centers, the new technology from Fujitsu Laboratories is most successful in improving energy saving at data centers, where electricity usage is expected to grow. The company will be conducting field trials of this technology throughout fiscal 2016 at data centres operated by Fujitsu Limited. Once the field trials are over, this technology will be put into actual operation in fiscal 2017, and incorporated into Fujitsu's operations management infrastructure software “FUJITSU Software ServerView Infrastructure Manager.”

What’s claimed to be the world’s longest wind turbine blade was unveiled in Denmark last week. Production of the 88.4m blade was a joint project of Adwen and LM Wind Power. The blade has been designed for Adwen’s AD 8-180, a wind turbine with 8MW nominal capacity and 180 meter rotor diameter. “When you are building the largest wind turbine in the world, almost everything you do is an unprecedented challenge,” Luis Álvarez, Adwen general manager said. “We are going where no one else has ever gone before, pushing all the known frontiers in the industry.” The next step is to ship the gargantuan component to Aalborg, where it will undergo rigorous testing.

 New York:

Nuke to stay open

Exelon is to assume ownership and operation of Entergy’s James A Fitzpatrick nuclear power plant in upstate New York after the two companies reached an agreement worth $110m following the state’s adoption of a Clean Energy Standard (CES) supporting the continued operation of nuclear capacity.

Under the agreement, Entergy will transfer Fitzpatrick’s operating licence to Exelon, which already operates Nine Mile Point and Ginna.

Subject to regulatory review and approval by state and federal agencies, the transaction is expected to close in the second quarter of next year.

Entergy had previously announced plans to close the single-unit 838MWe in January 2017 for economic reasons.

The CES adopted last week by the New York Public Service Commission explicitly recognises the carbon-free generation provided by New York’s upstate nuclear power plants ~ two units at Nine Mile Point and single units at RE Ginna and James A Fitzpatrick ~ as critical in enabling it to meet its climate change targets.

It provides a mechanism to ensure the units, at risk because of the economic challenges from the short-term nature of the deregulated market they operate in and competition from low-cost gas and federally subsidized wind power, to remain in operation.

Exelon has already indicated that approval of the CES means that it will invest millions of dollars into the upstate plants.

The company has now committed to refuelling Fitzpatrick in January 2017. — World Nuclear News 9/8/2016

Apple can start reaping the fruits of its $850m Monterey County solar power investment. Federal energy regulators Thursday approved the firm's application to start selling electricity at market rates. Apple's solar power investments can generate 20MW of electricity in Nevada, 50MW in Arizona and 130MW in California. The latter output will come from Apple's $850m partnership with sun-farm company First Solar, at the California Flats solar project in southeast Monterey County. “It allows them to sell electricity into the wholesale markets and also use the wholesale markets as sort of a hedge,” said GTM Research analyst, Colin Smith. “If they're buying power at 10 cents per kilowatt hour and wholesale power prices happen to move up to 15 cents, they can actually sell power directly and pocket the difference. This turns them much more into an independent power producer and really enables them to work the energy markets more freely.” Regulators in 2010 gave Google approval to make similar sales.

Not only journalists are finding the going tough in Egypt; solar developers are now also avoiding the area. When Egypt announced plans to develop renewable power in 2014, investors piled in, drawn by year-round sunshine and chronic electricity shortages. Two years on, many projects have stalled, hitting confidence among foreign investors Egypt sorely needs. Developers who prequalified for solar and wind projects under attractive feed-in-tariff (FiT) schemes say they face delays and currency risks while wrangling with the government over contract terms has complicated efforts to secure financing despite the country's gas shortages caused blackouts in 2013 and 2014. Italy’s Enel Green Power, which prequalified in 2015 for one solar and two wind projects under Egypt’s FiT schemes and entered a build-own-operate tender for a 250MW wind project. “Continuous uncertainty from the local authority in managing the process as well as delays in assigning contracts, have lead EGP to freeze its business development operations in the country,” an Enel spokeswoman said. A source from another consortium of foreign investors that prequalified for a solar FiT project said Egypt’s insistence on domestic arbitration in any dispute had prompted a multilateral lender that was co-financing the project to withdraw.

Just 56% of his utility’s generation capacity was beyond its useful life, Mark Johnston, general manager of Municipal Light & Power told the Anchorage Chamber of Commerce. “We’re building new generation because the stuff that we have is old,“ Johnston said. ML&P has worked with Chugach Electric Association to build the Southcentral Power Project, a modern, high-efficiency, gas-fired generation facility now in operation in south Anchorage. ML&P has also been building its own high-efficiency power plant, called Plant 2A, adjacent its existing power generation units in the north of Anchorage. Johnston said, although ML&P’s 20-square-mile service area is quite small, the utility serves many of the businesses that operate in Anchorage. And, while only about 20% of the utility’s customers are commercial organizations rather than residential, those commercial customers account for about 88% of the utility’s total load, he said. About 18% of the utility’s power comes from hydropower systems at Eklutna, north of Anchorage, and from Bradley Lake on the Kenai Peninsula. The remaining 82% of the power comes from various gas-fueled facilities.
