Stanley Reed for The New York Times: A project to install hundreds of wind turbines in the Fosen peninsula area of Norway at one point was shelved as unfeasible. The strong breezes that whip off the sea can shift and swing unpredictably, while the soaring cliffs and steep drop-offs create turbulence that wears out expensive equipment.
The venture was rescued with a lot of help from the mathematical calculations of Vestas Wind Systems, a Danish wind power company. Vestas used data to figure out how to use more powerful turbines for the project, and precisely where to place them. That meant the utility developing the facility could buy fewer turbines, helping cut costs and balancing the economics of the $1.2 billion project.
The company is at the forefront of efforts to make wind a competitive source of energy, rather than just a subsidized experiment. In doing so, it has become a model for the renewables industry, which has struggled at times to remain viable while facing cuts to government subsidies and volatile oil and gas prices. Vestas understands the fickleness of the renewable energy business. Cont'd...
BrainGrid's "Sentroller" is an advanced solar energy monitoring technology platform that delivers a reliable and fully featured means to connect and relay wireless data. So in essence anyone can easily to remotely monitor and manage systems and infield equipment previously deemed as "unmonitorable".
Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
