Wind and solar curtailment is worst where these renewables are poorly integrated into the grid. The further their energy can reach the more regions they can service, thus minimising curtailment. If they don’t reach far, local coal plants must ramp down - but only if they’ve been retrofitted to be able to do so. It’s a problem faced by many countries: spend money on the retrofits or the integration? Writing for the Regulatory Assistance Project … [Read more...]
California fires and blackouts: would non-profit utilities be more reliable, safer, cheaper?
The wildfires in California ignited by poorly maintained transmission lines have themselves ignited a debate about whether the guilty - and now bankrupt - energy utility PG&E (the largest in the state) should now become publicly owned. That in turn has led Severin Borenstein at the Energy Institute at Haas to consider the pros and cons of public v private in this vital activity. The first thing to note is that electricity transmission and … [Read more...]
Midwest U.S. grid operator MISO: modelling for a clean energy future
Planning can’t be easy for a grid operator. Take MISO which operates one of the world’s largest energy markets. They’re responsible for integration and bulk transmission across the central U.S., but decisions on the actual future energy mix and demand are being made elsewhere: by state governments, utilities and consumers big and small. Given the amounts invested in infrastructure and the lead times involved, no one will thank MISO if their … [Read more...]
China plans UHV transmission lines that span continents
China’s Global Energy Interconnection (GEI) project aims to create a worldwide network of UHV transmission lines that can deliver electricity between continents. If successful, generating electricity in the most remote areas – think deserts and the Arctic – becomes viable, as does China’s ability to sell electricity directly to Europe. First, two main technological challenges have to be overcome: energy loss along transmission lines spanning … [Read more...]

Online condition monitoring: making sense of sensors in the age of the Smart Grid
Grid operators across Europe are experiencing higher maintenance and reinforcement costs than ever before and, without significant increases in funding, are realising that they must fundamentally change the way that their assets are operated, maintained and replaced. This means running assets closer to their operational limits, performing predictive rather than corrective maintenance and replacing assets as close to the end of their useful life … [Read more...]
