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.

Governments need to be careful removing base-load

What happens when you get rid of those base load stations? The price goes through the roof. Just ask the South Australians.

It’s that pesky wind, it does not blow when it is supposed to; not that these mere facts disturb wind devotees.

Last Thursday (July 16) at 1.45pm, the wholesale power price in South Australia was recorded at $1001/MWh, compared with prices of between $30/MWh and $32/MWh for the eastern states of Australia — at one point, the maximum price in the state hit $1400/MWh.

Electricity contracts for delivery next year and in 2018 are priced at between $90/MWh and $100/MWh in South Australia, compared with between $50/MWh and $63/MWh in Victoria, NSW and Queensland.

South Australia’s insistence on renewables (they have over 50%) has turned around and bitten it on the bum.

The electricity industry warned long ago this policy was fraught with idiocy but they do things differently in South Australia.

Late last year the government issued a policy statement which reads: “to realise the benefits (of renewables), we need to be bold. That is why we have said that by 2050 our state will have net zero emissions. We want to send a clear signal to businesses around the world: if you want to innovate, if you want to perfect low carbon technologies necessary to halt global warming — come to South Australia.“

Last week big business warned it would be closing down unless something was done about the high electrify price.

The government is blaming the interconnector which sits between Victoria and South Australia pumping dirty brown coal generated electricity to fill the gaps between the pristine wind power.

Mind you, the South Australian gleefully closed down the Northern Power station in Port Augusta in May — the alternative was to pay owner Alinta Power to keep it open.

State Treasurer and Energy Minister Tom Koutsantonis explained: “The truth is the reason it is closing is it couldn’t make money in this market,” he said. ”The reason it can’t make money in this market is even though it does pour in relatively cheap power into the grid, renewable energy is cheaper.”

That’s not quite correct.

The State Government in South Australia has a policy of using renewables in preference to coal-fired generation.

In other words it forced Inland to close.

The economics of electricity generation call for a 90% back-up of renewable generation. And guess what that is?

Either gas or coal-fired generators.

Koutsantonis even pledged to: “smash the Australian electricity market” which effectively runs the eastern seaboard of Australia including Victoria’s electricity generation and supply.

This, of course, means generators in Queensland can ramp up supply to cover shortfalls in Victoria — it’s called a grid.

And despite its critics, it works very well.

South Australia is not on the grid and combined with on overwhelming wind component, its wholesale price since 2015 has been being consistently higher than the rest of Australia.

Koutsantonis has had to eat his words.

He pleaded last week with the privately owned, mothballed gas-fired electricity generator located on the Port River in Adelaide to fire up to make up the electricity shortfall in the state.

Sadly, the idiocy permeates the Australian Labor Party which has a target of 50% renewables for the whole country.

The Obama administration unveiled a plan Tuesday aimed at helping middle-class and low-income communities put solar panels on their roofs. Homeowners could choose to harness electricity from the sun, buy energy-efficient water pumps and make other energy-saving upgrades at no cost upfront, eventually paying it back through their property tax bills. While this type of clean-energy financing has existed for years, officials said backing by the federal Housing and Urban Development and the Department of Veterans Affairs should expand access to families who may not afford it otherwise. The White House estimated the effort would bring solar power to about 250,000 middle-class and low-income homes by 2020. "Solar panels are no longer for wealthy folks who live where the sun shines every day," President Barack Obama said in a video message accompanying the announcement. In recent years, technological advances have made it cheaper to install rooftop solar panels, Obama senior adviser Brian Deese said in a telephone briefing with reporters. California Gov. Jerry Brown praised the effort, saying it would lead to more solar installations and energy-saving retrofits around the country.—


In 2016, nearly 300MW of electricity generating capacity is expected to come online from dams that did not previously have electric generating units, commonly referred to as nonpowered dams (NPDs). NPD capacity additions make up 92% of the 320MW of planned hydroelectric capacity for 2016. Expected capacity additions at NPDs in 2016 are large compared to recent NPD additions, which totaled 126MW over 2006-15, but relatively small compared with total US hydroelectric capacity of nearly 80,000MW as of April. The National Hydropower Association estimates that 3% of the nation’s 80,000 dams generate electricity. Existing conventional hydroelectric generators in the United States provided 251m megawatthours of electricity in 2015, or about 6% of annual total net generation. Unlike other forms of renewable-fueled electricity, such as solar and wind, hydroelectric capacity additions have been relatively modest in recent years.


PPL Electric Utilities on Wednesday (20/4/2016) completed the Northeast-Pocono Reliability Project, a $350m investment in new substations and power lines. Originally projected for completion in late 2017, the work was done more than a year early, however, while construction is complete, land restoration is expected to continue to the end of this year. The work included three new substations, nearly 60 miles of new 230-kilovolt power lines, and other improvements. Northeast-Pocono is the second major transmission project to be completed by PPL in the past year. The $648m Susquehanna-Roseland transmission line was completed in early May 2015. PPL Electric Utilities provides electric delivery service to more than 1.4m homes and businesses in Pennsylvania. With 2300 employees, PPL Electric Utilities is a subsidiary of PPL Corporation.
