How London Paid a Record Rrice To Dodge a Blackout

The crisis, which quietly played out within the control room of the British electricity system, shows the growing vulnerability of energy transportation networks — power grids and gas and oil pipelines — across much of the industrialized world after years of low investment and not-in-my-backyard opposition…Talk to most industry executives and you quickly get the sense that we are sleepwalking into more blackouts. Discuss the problems with the engineers who manage the system day-in, day-out, and that danger appears even closer…

In a normal situation, without the traffic jams on the grid, the UK should have been able to send power to the southeast of England from elsewhere in the country — even from all the way in Scotland…

The world is investing about $300 billion per year in power grids, an amount that has barely changed since 2015, according to the International Energy Agency. It isn’t enough, as the global economy electrifies and deals with a shifting generation map, with intermittent renewable energy like solar and wind replacing polluting — but dependable — coal- and gas-fired stations.

Reserve margin may need to rise to 300% by 2040 as more renewables added to grid: ISO New England
www.utilitydive.com/news/new-england-future-grid-study-iso/6…
The reserve margin on the ISO New England system may need to increase from about 15% to 300% by 2040 in some scenarios, as more renewables are added and dispatchable generation is retired to meet state clean energy goals, according to a July 29 report from the grid operator.

The first phase of the ISO’s Future Grid Reliability Study models a variety of decarbonization scenarios in 2040 and concludes they “may require a significant amount of gas or stored fuels to support variable resources.”

A scenario where reliability criteria are met using only solar, wind and storage, would challenge the transmission system and require “an outsized amount of land or offshore areas” for wind and solar farms, the report found.
