World's largest geothermal plant opens in Kenya as global development steams ahead

Kenya’s 280 MW Olkaria geothermal power plant, the world’s largest, began commercial operation today, with an opening ceremony held yesterday and attended by government officials. The plant (pictured) will provide almost 20 per cent of the nation’s total power capacity.
Kenya is among the world’s most active regions for geothermal development, and figures from the national statistics bureau showed that 381.6 MW of geothermal power was generated in December alone. According to utility Kenya Electricity Generating Co (KenGen), geothermal power now accounts for 51 per cent of the nation’s installed power capacity, displacing hydropower as the top energy source.
“The growth rate seems almost preposterous but we’re seeing 10 geothermal rigs running just in Kenya — they are going crazy with money flowing in,” said Mike Long, executive vice-president of US-based strategic consultancy Galena Advisors. “Geothermal will be growing in Kenya, maybe not to the numbers the government is publishing, but 200 MW per year will be fairly sustained for five+ years.”

Siemens wins contract for Dubai gas-fired power plant expansion

Siemens has won an AED1.47bn ($400m) contract with the Dubai Electricity and Water Authority (DEWA) for theexpansion of the utility’s gas-fired M-Station power and desalination plant.
The 2060 MW combined-cycle plant (pictured), completed in 2013, is to receive two new gas turbine generators, two heat recovery steam generators and one back press turbine, which will increase its power capacity to 2700 MW and its thermal efficiency rating from 82.4 per cent to 85.8 per cent, Siemens said.
The expansion project is being managed by Mott MacDonald, and is scheduled for completion in April 2018.
The plant, located 35 km southwest of Dubai in the port town of Jebel Ali, is the UAE’s largest power and desalination facility. In addition to power, it produces 140 million gallons (636 million litres) of desalinated water per day.

Hungarian nuclear power plant could be blocked by Brussels

The proposed plan to build two 1200 MW nuclear reactors at Paks in Hungary has come under scrutiny by the European Commission and may be blocked.

Under anti-trust law, the proposed $12bn development is being investigated after some details of the contracts with Russia’s Rosatom were said to be concealed on grounds of national security provoked suspicion among opponents to the project.

The anti-trust issue is being described as a possible case of violation of EU law by officials

A veto or prohibitive fine could be in the offing according to the FT with Euratom, the nuclear watchdog, withholding approval for the plant’s fuel supply on technical and financial grounds, although talks are ongoing. All nuclear fuel supply deals by EU member states must receive the green light from the agency.

There is also concern about overdependence by Hungary on Russia for energy. The country already relies on Russia for 80 per cent of its oil and 60 per cent of its gas imports, but Budapest still awarded contracts to design, build and maintain the reactors in December.

How do you calculate how many kWh a solar installation will produce in a year?

Remember your utility charges you by the kWh, but solar installations are sold by the watt or kilowatt.
But there’s a quick way to roughly convert kW into kWh.  In our part of the country, when the solar installation is ideally located (facing perfectly south, no shading), each 1000 watt (1kW) section of installed panels produces 1,350 kWh/year.  So simply multiply the kW size of the system you’d like to purchase by 1,350. For example: 6 kW system x 1,350 kWh = 8,100 kWh expected annual production. If you use 15,000 kWh annually, this is more than half your electric bill!
The federal government has a online calculator that’s available to the public called PV Watts .    It can provide a more refined realistic estimate of what to expect.  It can be a little tricky to use if your unfamiliar with it.  Ask us and we can help you.

Organic solar cells reach manufacturing milestone

In an impressive feat of engineering, scientists in Denmark have devised a rapid, scalable and industrially viable way to manufacture large sheets of flexible organic tandem solar cells. Their successful application of roll-to-roll processing is a significant achievement for this emerging renewable technology.
An organic photovoltaic (OPV) solar cell is a polymer-based thin film solar cell. OPV solar cells have been the focus of much research as they are lightweight, flexible, inexpensive, highly tuneable and potentially disposable. They are also unparalleled in the number of times that they can pay back the energy used in their manufacture.
In the quest to improve the efficiency of OPVs, which, in addition to operational lifetime, is currently their key limitation, various new materials, processing methods and device architectures have been investigated. Among these is the tandem cell, where multiple junctions are stacked upon one another. This can increase the efficiency of the cell by not only increasing the number of junctions, but, along with careful selection of complimentary materials, can make it possible to harvest photons from a broader region of the spectrum. However, this more complicated architecture renders their manufacture significantly more challenging.
