AWS Truepower’s monthly wind performance maps are released shortly after the end of each month. This new service offers an enhanced look at the company’s Wind Trends, which provide a quarterly snapshot of wind performance. The new monthly performance maps show deviations in the wind resource from average conditions in every region of the world…
Renewable NRG Systems introduces new SymphoniePRO data logger
Renewable NRG Systems (RNRG), a designer and manufacturer of decision support tools for the global renewable energy industry, has launched a new data logger that is specifically engineered to improve the performance of wind and solar measurement campaigns. Building on RNRG’s well-known Symphonie series of user-friendly loggers, the SymphoniePRO logger brings significant upgrades in terms…
Morgan Advanced offers new carbon brush grade for improved turbine performance
Morgan’s Electrical Carbon business has developed a new carbon brush grade suitable for wind turbine applications that drastically improves up-time in some of the most demanding conditions. The LL587 carbon brush grade maximizes performance through extended brush life combined with minimal wear to slip rings. Extensive field testing by Morgan Advanced Materials and several wind…
First wind farm trials commence for new bearing life extension technology
Forensic investigation undertaken by Ricardo MultiLife, on behalf of wind energy clients, has identified an important similarity in bearing failure mechanisms commonly arising in wind turbine drivetrains. Wear on the inner race of bearings in the inaccessible planetary stages of the gearbox tends to be concentrated over a small arc of some 40°, and can…
Wind farms perform best when the sun is out
When set up in groups, wind turbines in the front rows cast a wind shadow on those behind them, lowering their performance. These effects dissipate fastest under convective conditions, according to Swiss researchers from EPFL, in a recent journal. Obviously, wind farms work best when it’s windy. But aside from wind-speed and direction, there are…
Greensolver Index adds 1.7 GW of managed wind assets to its database
Greensolver, the independent wind and solar farm asset manager, has announced that its unique performance benchmarking tool, Greensolver Index, has now added 1.7 gigawatts (GW) of managed wind assets to its database. With mature onshore wind projects of increasing interest to investors, there’s a growing demand for these assets to be independently managed by a…
Understanding variability is key to Mexican wind investment
The 2014 Mexico Wind Performance Map, released by Vaisala, delivers positive news for much of southern Mexico where above-normal wind speeds boosted performance at many of the country’s operating wind projects. Conversely, wind speeds below the long-term average in Mexico’s interior negatively affected overall production at wind farms in that region. These departures from mean…
