Ukraine is shaping its gas infrastructure and regulations to integrate into the EU market. On the infrastructure front, its interconnectors with neighbours, extensive pipeline network and storage facilities are making it an increasingly important European player, explains Aura Sabadus writing for the Atlantic Council. The gradual opening up to EU free market rules are evidenced by its gas prices following those of the EU. Ukraine's attractive … [Read more...]
Negative electricity prices: lockdown’s demand slump exposes inflexibility of German power
The lockdown has unexpectedly allowed us to model certain aspects of the energy sector’s possible future. One is the oversupply of variable renewables into the grid. In Germany, a slump in demand plus an exceptionally sunny and windy few months sent wholesale electricity prices negative and to record lows. Fossil generators calculated that paying buyers to take electricity was cheaper than performing a shut-down re-start sequence, so they did … [Read more...]
U.S.: Counting Renewables jobs and projects under threat, what can be done and why
All sectors across all economies are trying to add up their potential job losses and projects in jeopardy, then telling their governments to prioritise them for support. Mike Jacobs at the Union of Concerned Scientists looks at renewables in the U.S. He quotes news reports that over 100,000 workers in this fast-growing industry filed for unemployment in March 2020. On top of that, the already planned expiry and phase-down of certain targeted … [Read more...]
Regulatory challenges to foster cross-border trade in electricity systems with increasing shares of renewables
The share of renewable generation in Europe’s power system is rising fast, but interconnection is not keeping up. Join us on May 19, 2020 to discuss this and related issues. More wind and solar makes the supply of electricity much more dependent on the weather. Nobody wants to build capacity only to switch it off when there’s too much heading onto the local grid. This could put an extra strain on delivering the Green Deal. One solution is to … [Read more...]
Better grid integration beats coal plant ramping to reduce wind, solar curtailment
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...]
Fieldfisher Interconnectors Forum – Brussels, 21 March 2019
The Fieldfisher Interconnector Forum will take a highly topical look at Interconnectors across Europe and the UK. This free half day event will cover significant legal developments and hot topics, including: The Outlook for Interconnectors - Future Opportunities Brexit and Future Energy Trading Scenarios Energy Market and Regulation Updates Environmental and Planning Perspectives Attendees will hear from Will Bridges, … [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...]
