NATGAS: Increasing Role of Gas Supply Flex for Energy Security: IEA
NATGAS
Gas supply flexibility plays an increasingly key back-up role in ensuring heat and electricity supply security in renewables-rich markets, according to IEA analyst Greg Molnar.
- There is a qualitative change in the gas role in an increasingly complex and weather-dependent electricity system amid rapid renewables expansion.
- Carefully assessment of asset investment is required to enable flexible gas supplies, including gas storage and reserve mechanisms.
- Storage withdrawals provided US gas supply flex when winter storm Heather drove gas demand to an all-time high of 4 bcm/d and gas-based generation rose 40% in just a few days.
- Gas-fired power generation in India rose by around one-third though May-July 2024 amid summer heatwaves. Flexible LNG procurements helped cover the incremental gas demand.
- Gas-fired power output in Brazil increased by nearly 600% between June and October due to a steep decrease in hydro power output with flex provided by LNG.
- In Europe, dunkelflaute episodes drove gas-based generation up 80% y/y in H1 Nov with increased supply from gas storage.
