Pairing solar and storage challenges gas peakers

Gas peakers have been around even before the recent rise of renewables made them even more indispensible. How else could grid operators fill in the void created by the vanishing solar generation when the sun sets at the end of the day or when wind stops spinning the wind turbines’ blades? And with natural gas […]

Nuclear power in a clean energy system

The International Energy Agency (IEA)  says wind and solar energy need to play a much greater role in order for countries to meet sustainability goals, but it is extremely difficult to envisage them doing so without help from nuclear power. Nuclear power today makes a significant contribution to electricity generation, providing 10% of global electricity […]

The contract includes the supply and installation of 49 V150-4,2 MW wind turbines with a 125-meter hub height. The power […]

To monitor wind turbine blades

Up to 23% of wind turbine failures can be caused by blade damage, with up to 25 to 30% of wind farm operation costs spent on operation and maintenance. Current damage detection options are limited and are used on an ad hoc basis at each turbine. The new ping monitor is an innovative acoustic solution […]

Renewable energy business focus to accelerate growth

GE says it intends to intensify its focus on the growing renewable energy market by consolidating all of the company’s renewable and grid assets into a single, simplified renewable energy business. Global demand for renewable power generation and the associated grid integration continues to increase globally with renewable capacity additions of 178 GW accounting for […]

Wind lidar measurements from a drone

Lidar developer, ZX Lidars, has demonstrated the use of drone wind lidar for vertical and horizontal profiling to accurately measure wind conditions remotely and above or ahead of their installed position. These accurate, independent wind measurements are a cornerstone in the development, construction and operation of wind farms globally. The company has now achieved accurate […]
