All Articles about Battery Storage
With Germany on the brink of a pivotal election, we want to share our high-level views on energy policy and the key considerations for voters. We’ve outlined five fundamental theses to keep this concise and to the point.
Electricity (cross-product) price volatility has historically been closely linked to overall price levels. This trend seems to have ended in 2024 in Germany, as low marginal cost renewables are pushing the overall wholesale price level down, while peakers such as gas and batteries need to finance their investments in relatively few but increasingly expensive production hours
FlexPower GmbH, PowerField Energy B.V., and Spectral have commenced trading operations for the co-located Battery Energy Storage System (BESS) and Photovoltaic (PV) plant in Wanneperveen.
This blog post is the third in a series of articles about hedging price volatility using standard shapes such as wind and PV, as well as more novel and somewhat non-standard ones, such as the FlexHL (Battery). While the first two articles were explainers for consumers, this one is for suppliers who are looking to sell their flexibility, i.e. BESS owners.
In this subsequent blog, we extend our discussion from part I and look at how to use Flex HL (battery) shapes to hedge against price volatility.
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.
Over the last year we became increasingly involved with the “science” of modelling past and future revenues of battery energy storage systems (BESS) and now decided to shed some light on this practice. We believe that customers are being sold a lot of voodoo for science and that the incentives in this industry are not at all well aligned.
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).
