The joint venture led by Danish wind company, Vestas, and Japanese engineering company, Mitsubishi Heavy Industries, Ltd has created the most powerful turbine in the world.

MHI Vestas’ new wind turbine generator has a 9.5MW capacity, and is based off of the company’s previous V164 platform.

In order to make the new model, MHI Vestas had to redesign the gear box for extra power capacity, as well as upgrading the cooling system and the generator.

The nacelle supporting the generator is 20m long by 8m, and weighs a total of 390 tonnes.

The blades of the turbine are 80m long, and each individual one weigh 39 tonnes. The hub height of the machine is 105m, with the tip height reaching 187m.

The joint venture claims that the overall cost of generating power will fall down due to the amount of power a single turbine can create, therefor needing fewer and lowering installation and maintenance costs.

“As a leader in the offshore wind industry, we are committed to lowering the cost of energy through innovative turbine technology,” stated CEO of MHI Vestas, Jens Tommerup.

“The launch of our V164-9.5 MW turbine is a testament to that leadership and to the ingenuity of our engineers and technicians. The V164-9.5 MW is built on the industry-leading V164 platform, the most powerful platform in operation. Just one single turbine is now capable of powering more than 8,300 UK homes.”

All but two UK regions failing on school energy efficiency

Yorkshire & the Humber and the North East are the only UK regions where schools have collectively reduced how much they spend on energy per pupil

Most schools are still "treading water" on implementing energy efficient technology, according to new analysis of Government data from eLight.

Yorkshire & the Humber and the North East are the only regions where schools have collectively reduced how much they spend on energy per pupil, cutting expenditure by 4.4% and 0.9% respectively. Every other region of England increased its average energy expenditure per pupil, with schools in Inner London doing so by as much as 23.5%.

According to The Carbon Trust, energy bills in UK schools amount to £543 million per year, with 50% of a school’s total electricity cost being lighting. If every school in the UK implemented any type of energy efficient technology, over £100 million could be saved each year.

Harvey Sinclair, CEO of eEnergy, eLight’s parent company, said the figures demonstrate an uncomfortable truth for the education sector – namely that most schools are still treading water on the implementation of energy efficient technology. Energy efficiency could make a huge difference to meeting net zero ambitions, but most schools are still lagging behind.

“The solutions exist, but they are not being deployed fast enough," he said. "For example, we’ve made great progress in upgrading schools to energy-efficient LED lighting, but with 80% of schools yet to make the switch, there’s an enormous opportunity to make a collective reduction in carbon footprint and save a lot of money on energy bills. Our model means the entire project is financed, doesn’t require any upfront expenditure, and repayments are more than covered by the energy savings made."

He said while it has worked with over 300 schools, most are still far too slow to commit. "We are urging them to act with greater urgency because climate change won’t wait, and the need for action gets more pressing every year. The education sector has an important part to play in that and pupils around the country expect their schools to do so – there is still a huge job to be done."

North Yorkshire County Council is benefiting from the Public Sector Decarbonisation Scheme, which has so far awarded nearly £1bn for energy efficiency and heat decarbonisation projects around the country, and Craven schools has reportedly made a successful £2m bid (click here).

The Department for Education has issued 13 tips for reducing energy and water use in schools.
