Large-scale vs. small-scale solar: Why residential rooftop solar may be threatening the energy transition

Germany has reached a record level in the installation of solar systems with 15 GW in 2023. However, problems are now beginning to emerge with rooftop solar.

A new index by FlexPower shows the current and historical value of flexible dispatch resources in energy trading

New Index Calculates Value of Flexibility in the German Electricity Market

The FlexIndex measures on a daily basis the revenues that operators of flexible assets can achieve in Germany’s short-term spot market. The index is based on a reference battery with a storage capacity of one megawatt-hour and a power of one megawatt.

2023 price update: How to Purchase Power in the 20s and 30s, Part I: Hedging with Wind and Solar Shapes

In recent years, if you’re involved in the power sector, you’ve likely come across discussions about Power Purchase Agreements (PPAs). Some consider them a cure-all for advancing the energy transition, and we, too, recognize their crucial role. However, it’s essential to grasp that a PPA is essentially a contract for buying or selling power, without specifying the type.

Cross-Market Energy Arbitrage for Battery Storage – How does it work?

We are often asked how the financial optimization (or: arbitrage) of a battery across the different market places of the spot market works. We show this x-market optimization here by way of example focusing on the day-ahead spot market (hourly auction at 12 noon), intraday quarter-hourly auction (at 3 p.m.) and the so-called intraday continuous market (quarter-hourly products up to five minutes before delivery).

German Power Traders demand Implementation of EU Law in Balancing Group Management

17 German power traders for renewable energies, who place well over 45 gigawatts of solar and wind power on the power exchanges every day, fear negative effects on the market integration of renewable energies due to the current legislative proposal for the new German Energy Industry Act.

How Price Caps (Taxes) will lead to the Destruction of Green Power

The German government plans to introduce a price cap (essentially a tax) for energy producers. This will likely lead to the curtailment of valuable green energy production at times of positive prices (worst case). Best case it will introduce a minimum price floor in markets exactly at the level of the marginal tax rate.
