About a third of European grids are over 40 years old. A rapid physical overhaul would be impossible, so the addition of a layer of digital technologies is the key to preparing them for the distributed and intermittent generation from renewable sources, the increased electricity demand from transportation, heat pumps and other sectors, and for ensuring energy efficiency at all levels. It’s why the EC expects about €584bn of investment in Europe’s … [Read more...]
Replacing centralised power with Distributed Energy Systems needs new policies and coordination
We need integrated resilient smart grids that can accommodate the rapid growth of intermittent renewables as well as the rise of “prosumers” who both buy and sell electricity into the grid. This is the focus of three online discussion sessions on February 8th, 9th and 10th organised and hosted by power management company Eaton. The proliferation of multiple generation sources (solar, wind, batteries and other clean, flexible technologies) means … [Read more...]
Can full-scale Distributed Solar really save $473bn in grid investments?
A giant model of the entire US electricity sector which captures distributed energy resource (DER) potential has been getting a lot of attention. It estimates that distributed solar and storage can save $473bn in system-wide costs when deployed at scale (enough to power more than 25% of US homes). Rooftop solar is definitely much more expensive than grid generation, but its location (on your own roof) avoids a range of costly transmission and … [Read more...]
