Several farmers in North Kohala, Hawaii, are now benefitting from an innovative off-grid water-pumping system powered by a Northern Power NPS 100 wind turbine. Like many others in remote locations and island communities, North Kohala farmers have been searching for an alternative to using polluting, expensive diesel fuel to generate electricity. This microgrid project, known as SkyGrid Energy, marks the growing trend of turning to affordable, clean, renewable wind energy as the solution. The NPS 100 wind turbine is specifically designed to support microgrids with its sophisticated voltage controls and no inrush current, thereby relieving stress to the system. In addition, the NPS 100's ability to control reactive power independently of wind speed more reliably meets energy demands, a crucial component of microgrids.

The SkyGrid Energy microgrid has been fully operational since April 2013. In addition to the NPS 100 wind turbine, which is the primary source of energy production, the system also includes a battery bank and solar panels. The system is capable of pumping more than 30 million gallons of water annually and is being used to irrigate 400 acres of agricultural land and support 14 participating farms and agricultural businesses. The project was partially funded by the U.S. Department of Energy through the Hawaii Renewable Energy Development Venture. Gen-X Energy Development LLC, the project developer, plans to replicate and deploy this microgrid solution throughout Hawaii and other island communities.

"Besides providing innovation for a better world and helping increase our independence from fossil fuels, the new microgrid is also helping provide a reliable and cost-effective solution for Hawaii's agriculture industry. This Northern Power turbine is critical to this microgrid's success," said Fred Brown, Gen-X Energy Development LLC co-founder.

Northern Power Systems has been an integral part of the evolving microgrid market for 40 years. Northern Power Systems turbines have been used in microgrid projects all around the world, from Alaska to Newfoundland and the Bahamas to Antarctica.

To learn more about the SkyGrid Energy project and microgrids, please join Northern Power Systems at two upcoming events. At the Distributed Wind Expo 2013 in Rochester, NY (June 11, 2013), Alan Axworthy, Director - Application Engineering, will present a case study of the SkyGrid Energy microgrid. Later in the month, on June 24, Paul Dawson, Director - Sales, Marketing and Business Development for the Americas, will present on microgrids at the Wind-Diesel 101 Workshop, at the Renewables in Remote Microgrids Conference in Toronto, Canada.

Northern Power Systems is a fully integrated company that designs, manufactures, and sells wind turbines into the global marketplace from its headquarters in Vermont, USA, with European headquarters in Zurich, Switzerland and a significant presence in the United Kingdom and Italy. The Company's proven, next generation PM/DD, wind turbine technology is based on a vastly simplified architecture that utilizes a unique combination of a permanent magnet generator and direct-drive design. This proven approach uses fewer moving parts, delivers higher energy capture, and provides increased reliability due to reduced maintenance and downtime. Northern Power Systems currently manufactures the NPS™ 60 and 100 turbines.

With over 2.5 million run time hours across its fleet, Northern Power turbines provide customers with clean, cost effective renewable energy.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
