Improving grid response to support climate targets and increased renewables [Energy Post event video]

by Leave a Comment

We present our video of the online discussion from February 24, 2021 on smartgrid response. Digital, automated, data-driven smart response systems can play a key role in grid security and stability going forward. This makes asset monitoring and controllability - underpinned by the Smart Grid Indicator which is now part of the EU Electricity Directive (Article 59) - a vital link in the chain. Taking part were Vera Silva, COT, General Electric and … [Read more...]

Policy-makers still undervalue Energy Efficiency as a grid resource

by and

Supply-side solutions to grid stability are few in number, and expensive. More baseload generation, electricity networks, capacity markets that pay power plants all year round to be available for dispatch during a few peak hours. Demand-side solutions are usually smaller, and multitudinous: building fabric improvements, equipment upgrades, customer behaviour interventions, and more. So, for grid stability, the principle of “Efficiency First” - … [Read more...]

ELCC: how to measure grid stability as renewables are added

by

We cannot just swap 24/7 fossil fuel power plants for intermittent renewables. To prevent electricity shortfalls the capacity of a solar or wind plant must exceed that of the fossil fuel plant it replaces. But by how much? That’s the question that the Effective Load Carrying Capability (ELCC) metric is designed to answer. It’s not a new concept, but is now becoming very important. Mark Specht at the Union of Concerned Scientists explains the … [Read more...]

Calculating the energy saved if home working becomes the norm, globally

by and

The global lockdown has resulted in a jump in home working and a collapse in commuting. If, post-lockdown, this new lifestyle is widely embraced, will it mean a reduction in total energy consumption and, if so, by how much? Daniel Crow and Ariane Millot at the IEA have crunched the numbers to attempt to answer this question. The first observation is that although car use will drop, residential energy consumption will rise. This is what makes the … [Read more...]
