Gigha Green Power Limited (GGPL) is a community-owned company that are installing a 4th turbine on Gigha, providing more income to the island for all its future projects such as it Housing Improvement Project.
Following completion of the necessary due diligence work relating to the funding and insurance arrangements, over the weekend of 10th May 2013, Neil and Michael brought with them a display of agricultural equipment that they had restored, some of which originally from Gigha. They gave displays of harrowing and ploughing when the weather permitted and many folk on Gigha had a go themselves, under the guidance of the experts of course! The last man to use the heavy horses on Gigha, John McNeill , was keen to get behind the plough again and it was clear that in the passing 60 odd years he hadn't forgotten a thing.
A buffet was provided in the Gigha hotel by Good Energy and Nsure Renewables, Insurance Brokers - companies who have had a long standing relationship with Gigha. Thanks also to Calmac for providing tickets for the ferry.
GGPL chairman Willie McSporran said the turbines, known locally as the Dancing Ladies, are a key part of the island's future, adding: "It's difficult to overstate the importance of the Dancing Ladies. They have produced the surplus we need to attract further finance, debt and equity to invest in the island's future. The fourth turbine project is crucial to our continued success and without the support of key agencies like REIF and the Co-operative Bank, we simply could not have brought it to fruition."
The weekend was a real success and all who attended would like to thank Neil, Michael and their family and friends.
Nsure Renewables wish Gigha every success with their 4th Dancing Lady!
Due to the grid connection limitation Evance has installed the R9000 Grid+ system, so enabling the maximum energy from each 5kW turbine to be captured and used, while only allowing 3.68kW to be connected to the grid, so complying with the requirements of G83.
"Stronsay has a great natural wind resource so, by installing our Grid+ system, Scottish Water is able to harness this renewable energy for use at the water treatment works. The three turbines will be able to generate around 55MWh of electricity a year, which will mean nearly an 80 per cent reduction in the energy costs of running the works," comments Tim Sammon, Director of Evance Wind Turbines.
"We have a few hundred turbines installed on the Orkney Islands. These customers have turned to Evance as the R9000 has proved its reliable and continuous operation in all the wind conditions experienced on the islands," stated Tim Sammon.
Evance is pleased to be working in partnership with Scottish Water to help harness wind power and so reduce the energy costs of running a vital service for the Scottish community.]]>
And so Liquid Robotics' engineers dumped their robots into the rolling water and turned them loose, uncertain as anyone else whether the robots could survive the weather, waves, and wildlife they would surely encounter on a trans-Pacific crossing. There are sharks out there, after all. Massive waves and gale-force winds. There's a whole lot of saltwater out there, itself a force for destruction and disruption of mechanical systems. And yet almost exactly a year after launching the Wave Glider known as "Papa Mau" navigated around the Great Barrier Reef and arrived off the coast of Queensland Australia in May 2012, half a world away from where it started and only somewhat worse for wear.
For those not up to speed on Wave Glider, a quick primer: Wave Glider is the first unmanned and autonomous maritime robot that draws its propulsive power solely from the ocean's waves. The two part system consists of a float that rides on the surface of the water and a tethered submarine unit that moves beneath the surface roughly 23 feet below. Wave Glider doesn't turn wave energy into power for motors or anything like that--the unique construction of the robot allows it to gain a little forward thrust with every wave that lifts the float unit. It doesn't move fast, but as long as the ocean continues to move so does the robot.
That makes Wave Glider ideal for a range of scientific missions, the kinds of data gathering expeditions that don't need to move fast and in fact don't want to. Solar panels spread across the float unit can power an array of instruments, those include a weather station measuring air temperature, barometric pressure, and wind speeds, as well as a wave sensor recording height, period, and direction, a submersible fluorometer capable of measuring chlorophyll-A, and a CTD (conductivity, temperature, depth) payload also able to measure dissolved oxygen in the water. The sensor package wasn't designed to discover anything in particular, but simply to create an unprecedented data set--refreshed every ten minutes and uploaded to the Iridium satellite network. That's more or less the entire idea behind Wave Glider: gather ocean data consistently and without interruption, until the end of time if possible.

It beats a previous high of 3.8GW set in May and comes as a further 4GW of wind turbines are being installed, half on land and half offshore.
Just before 10am, wind turbines were supplying 10.8% of the total amount of electricity going into the grid while an additional 2.2GW of "green" power was going directly into local electricity networks.
