Overview
- TenneT reports corrective interventions have surged to about 2,500 a year in its area, up from one or two two decades ago.
- Roughly half of installed solar capacity—around 50–60 gigawatts—cannot be directly controlled, which at times exceeds demand and pressures system stability.
- The federal government earlier this year lowered the size threshold at which new photovoltaic systems must be controllable, a step TenneT calls important.
- Economy and energy minister Katherina Reiche plans to start the first auctions for state-backed gas plants by year-end, with support expected to cost billions.
- TenneT says managing bottlenecks and balancing north–south power flows is costly and the burden ultimately appears in consumer grid charges.
