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.

Flexicon
Everything you need to know about flexibility in energy markets in one place? Written by experts for experts and beginners alike? This is what we strive for with our Flexicon.
Knowledge is key
We are traders and engineers working to establish a 100% sustainable energy supply. Flexibility is key in this endeavour because flexibility is what we need to fill the gap in renewables generation. With our School of Flex, we want to share our knowledge on flexibility and invite you to collaborate.
Flex Index
"How much money can I make with a battery?", we get asked a lot. To answer this question, we created the FlexIndex, which is a transparent reference for the value of flexibility on the German power market. Check it out...

Battery Energy Storage System (BESS)
A Battery Energy Storage System (BESS) is a system that uses batteries to store electrical energy, which can then be released back into the electrical grid as needed. BESS can be used for a variety of purposes...

Functions & Components of a Battery Energy Storage System
A Battery Energy Storage System (BESS) features more than just the battery that stores electricity - there are multiple other functions and components in a BESS. These include power electronic functions, the functions of the control and management systems as well as metering and communication functions...

Marginal Costs
On commodity markets, the price is derived from the producers' marginal costs. This market-based pricing process is known as marginal pricing. On the electricity market the merit order model has become established because it describes, rather than prescribes, why power plants are used in a certain order.
Marginal Pricing
Marginal Pricing is an economic model that explains a specific type of pricing. It posits that in competitive markets, the equilibrium price (where supply and demand are equal) is largely determined by the producers with the highest marginal costs (at the equilibrium point).
Market Participation of a Battery Energy Storage System (BESS)
There are several forms of market participation for a Battery Energy Storage System (BESS) in energy markets. Check out our list of energy markets that are a good fit for flexibility from battery storage.
Market Value of Renewables
The market value is a metric that measures how valuable electricity coming from a particular plant is. It helps us understand how higher shares of renewables collectively lead to lower returns and its implications for the ongoing energy transformation.
P
Pay-as-Bid & Pay-as-Clear
Currently, electricity is largely auctioned on the exchanges through Pay-as-Clear Auctions, where the price for all suppliers is based on the highest bid. Pay-as-Bid Auctions, where each supplier is paid according to their individual bid, are intended to lower prices. But there's a catch.
Power Pricing
Power pricing on the wholesale market largely follows the laws of the market economy. Like many other wholesale prices, the power price is also distorted by regulatory market intervention on the producer side, for example through subsidies, taxes and CO2 pricing. However, pricing on the power exchange itself is based on competitive criteria.
R
REMIT (Regulation on Wholesale Energy Market Integrity and Transparency)
The REMIT regulation, formally known as the "Regulation on Wholesale Energy Market Integrity and Transparency," is a pivotal legislative framework within the European Union (EU) that plays a crucial role in ensuring the fairness, transparency, and integrity of the wholesale energy market.

Technical Specifications of a BESS
Capacity and capability determine the scale of a battery storage system. However, there are several other characteristics that are important for calculating the marketability and return potential of a Battery Energy Storage System (BESS)...
U
Uniform Pricing
Uniform Pricing refers to a situation where all buyers in a market pay the same price for identical products or services. This contrasts with price discrimination, where different prices are charged for similar transactions, depending on the buyer or seller.

Confessions of a Trader
Radical honesty is a rare animal in the wilderness of energy trading so we are proud to share some stories which are maybe harsh, quick and dirty but speaking the truth, the truth and nothing but the truth.
LATEST ARTICLES
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.
