Accurate weather forecasting for an affordable energy transition

Weather forecasts can bring down the cost and financial risks associated with new renewable energy infrastructure projects

“Climate is what we expect, weather is what we get,” as Mark Twain, US author, so succinctly put it. Accurate weather data detailing when the sun will shine and how hard the wind will blow is crucial to controlling the cost of the energy transition. The more accurate the data, the cheaper it becomes to rely on renewable energy and manage increasingly extreme weather events

Goal: Collection of enough data of sufficient quality to produce models that accurately predict weather extremes to reduce the risk of machine failure and increase the value of renewable energy

Challenge: Climate change is playing havoc with known weather patterns and meteorologists need latest input from renewable energy plant operators 

Key quote: You can always get the power you need…but having the power you need at the lowest possible cost, that is where the weather forecasts are valuable


Weather data plays an important role in making the transition to a clean energy economy affordable. It helps developers find locations with the best wind conditions, operators better manage the impact of turbulence on wind turbines and gives traders selling energy across borders greater clarity. With increasing proportions of renewable energy on the electricity grid, weather forecasts help lower the cost of integrating variable generation into the power system and ensure high system reliability, says John Zack from US-based UL Renewables. ...
