World's largest offshore wind turbine to be installed
Deepwater Wind's 30-MW Block Island pilot Wind Farm, located off the coast of Rhode Island, U.S., will receive five Haliade 150-6 megawatt (MW) offshore wind turbines from Alstom. The project will be one of the first offshore wind farms in the U.S. and will be the first to feature Alstom's Haliade 150-6 MW –the largest turbine installed in offshore waters. The five turbines will produce approximately 125,000 MWh of electricity a year, enough to power over 17,000 homes.
The company will manufacture the direct drive wind turbines and provide 15 years of operation and maintenance support for the Block Island Wind Farm owned and operated by Deepwater Wind, a developer of offshore wind in the United States. The Haliade 150-6 MW wind turbine features Pure Torque design for efficiency and reliability and its 150-meter diameter rotor provides an energy yield that is 15 percent better than existing offshore turbines, supporting the effort to drive down the cost of energy from offshore wind.
The Block Island project could lead to a larger utility-scale offshore wind farm of more than 1 gigawatt supported by a regional transmission system linking Long Island, New York and South-eastern New England. The project is aligned with The Bureau of Ocean Energy Management's “Smart from the Start” offshore wind program, which aims to accelerate the development of clean, renewable offshore wind along the eastern seaboard of the U.S.

In 2012, Alstom was part of Dominion Virginia Power's, Virginia Offshore Wind Technology Advancement Project that was selected as one of the seven U.S. Department of Energy's (DoE) advanced technology demonstration projects. Dominion Virginia Power is planning to submit a funding proposal to the DoE for the second phase of the project that will help validate the next generation of hurricane resilient offshore turbine, foundation designs and advanced controls technologies along with the new processes involved in installation and operation of such equipment.
In late 2013, Alstom successfully installed its 6MW Haliade, which at the time was world's largest offshore wind turbine, off the coast of Belgium. The company is part of a consortium led by EDF Energies Nouvelles that was awarded three projects in the first tender launched by the French government to install offshore wind turbines generating 3 GWs of wind power off the coast of France. The successful bid included a total of 240 Haliade 150-6 MW turbines.
All but two UK regions failing on school energy efficiency
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.
