Vestas receives order for high wind speed turbine

UK: Vestas has received a 50MW order for an E.ON-owned project in northern Scotland.

The order is for 25 V80 2MW turbines, which are designed for high wind sites. They will be installed on the Camster wind farm, in Caithness.

E.ON project manager Dean Guy said: “We see onshore wind as an important part of the energy mix here in the UK, and Camster wind farm is an important part of that.”

In November last year, RES ordered 14 V80s for a project in North Ayrshire.

 

Recently there have been a number of V80 orders from Chinese developers.

This includes a 48MW deal from GSI for a project in Huitengxile, in the Inner Mongolia Autonomous Region, and an 48MW order from Longyuan for a project in Zhongmen, Putian County, southeast China s coastal province of Fujian

Maryland turning to offshore wind energy

Maryland Offshore Wind TowersThe state began its pursuit of offshore wind generation Tuesday, a move that could lead to building 400-foot-tall turbines off Ocean City.

The Maryland Energy Administration asked wind developers to express their interest in building industrial-size windmills a dozen or more miles off the state’s 31-mile Atlantic coastline. At the same time, the energy agency said it is launching a study to gauge the economic viability and environmental impact of such a project.

“We know Maryland has great wind resources off our shore,” said Malcolm Woolf, state energy administrator. “We’ve got to figure out how best to tap into them.”

Maryland officials, eager to meet goals for more renewable energy sources, have approved two wind farms in the western part of the state. But Maryland is following other Mid-Atlantic states in pursuing offshore wind power.

Delaware recently settled on Bluewater Wind, a subsidiary of a national energy firm, to build a 230-megawatt string of turbines 13 miles off Rehoboth Beach. New Jersey has tapped Bluewater and two other companies to develop wind projects off its coast.

Woolf said the new study will give developers technical information on wind speeds and ocean depths, so they can decide where or whether to bid for building offshore turbines. The study, which is expected to be completed early next year, also will outline areas where turbines might not be appropriate, such as shipping lanes or sensitive marine habitats.

State officials, meanwhile, plan to huddle with local leaders to test community sentiment in Maryland’s beach resort to having turbines visible on the eastern horizon – though wind developers say their generators would appear no larger than a toothpick at those distances.

“We don’t want this to be tied up in community battles for years,” Woolf said, alluding to the long-running dispute in Massachusetts over building wind turbines off Cape Cod.

Wind Power Applications

Wind Power

To meet the electricity needs of a power company, a number of large wind turbines (50 kilowatts up to 2 megawatts) can be built close together to form a wind plant. Several power providers today use wind plants to supply power to their customers.

Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator. The blades act much like airplane wings. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind’s force against the front side of the blade, which is called drag. The combination of lift and drag is what causes the rotor to spin.

Wind turbines are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of faster and less turbulent wind.

Where It’s Available

Wind energy can be produced anywhere in the world where the wind blows with a strong and consistent force. Windier locations produce more energy, which lowers the cost of producing electricity. Moderate to excellent wind resources are found in most regions of the United States. However, the majority of the useable wind resources in the United States are found in the western Plains states. The wind resource maps from Wind Powering America can help you determine whether the wind resource in your area is adequate for wind power.

Wind Resource Maps

One of Wind Powering America’s key activities is to provide validated, high-resolution state wind maps. Below are two maps of the United States. The first map is a combination of high resolution and low resolution datasets for the United States as a whole. The second map of the United States indicates which states have their own validated, high-resolution wind resource maps, which states are planned, and other wind maps that have not been validated.
