Very clear demonstration of cannibalisation of frequency response revenues as batteries push out any legacy technology from these markets.

Fun sawtooth trading in 15-min day ahead market in Germany

I don’t expect it to stay as trading patterns evolve and generators pick up additional 15-min blocks or buy back lower end of period volume.

What does Spain’s battery storage buildout look like?

By 2029, the country could host up to 5 GW of installed battery capacity.

Germany’s intraday market is the deepest and most volatile in Europe. More than a million trades clear daily, with 96 delivery windows open and prices swinging within minutes.

For batteries, this is where speed and flexibility deliver exceptional returns.

We start tracking from above 6MW, so there are a few in the sub 100MW size that aren’t in the BM. Over 100MW, you have to be in the BM.

Ed Porter @edporter.bsky.social · 21d

It’s a few GW more than that as this is only the batteries registered in the Balancing Mechanism. So it’s more like 6GW today

Power Systems Transformation: Delivering Competitive, Resilient Electricity in High-Renewable Systems

The ETC sets out that global power systems dominated by wind and solar generation can reliably deliver electricity at costs comparable to or lower than today’s fossil fuel-based power systems in most ...

Ed Porter @edporter.bsky.social · 22d

What will low-carbon energy systems cost? And how does that compare to today?

Key to this is whether areas are sun or wind-dominated and the associated balancing required.

Definitely prefer generators holding more risk on volume and not being paid in constraints. I think this enables these large utilities to push for better siting / timing of work rather than leaving this with a central process.

Show me the incentives and I'll show you the outcome

They also procure RE CfDs, so hold the risk in the sense of a fixed price. Importantly, renewable generators don’t pass over the risk on curtailment, that stays with generators (unlike GB CfDs)

MACSE: Fixed returns to scale up Italian storage - Research | Modo Energy

Italy’s first MACSE auction on September 30th will contract 10 GWh of storage providing long-term revenues.

modoenergy.com

Ed Porter @edporter.bsky.social · 23d

Italy’s upcoming MACSE auction concentrates 10 GWh of storage procurement in the south and islands.

Why focus there?

- High renewable penetration
- Weak interconnection
- Acute flexibility needs

By targeting capacity where stress is highest, this ensures storage delivers the greatest impact.

How are batteries growing into Germany’s Automatic Frequency Restoration Reserve (aFRR) market?

Still more work to do to displace carbon-emitting plants.

A similar story to many transitioning power markets.
