About us
An independent market partner for generation and storage assets
Aarx Energy is a licensed energy trading company acting as a Balancing Responsible Party. We support owners and operators of generation and storage assets, as well as companies that buy, sell or manage an energy position on the wholesale market.
We bring together experience in trading, balancing, scheduling, technology and market strategy. Our clients get professional energy market services without having to build a full trading function in-house.
We are building Aarx for a market where an asset's performance depends not only on production volume, but also on the quality of trading decisions, balancing costs, profile management and the use of flexibility.
Our role
We help energy asset owners operate on the wholesale market in a professional, transparent and scalable way
We provide the expertise and processes needed for trading, balancing, scheduling and asset optimisation. This lets clients focus on developing and managing their asset or portfolio, while Aarx takes over the agreed energy market operations.
Our principles
01
Security and transparency
We operate under a clearly agreed mandate, with a defined scope of responsibility, settlement model and risk control rules. We focus on clear communication, transparent reporting and a predictable operational process.
The partnership model should make clear what we do, how we report on trades and where each party's responsibilities lie.
02
Value over volume
We focus on value creation, not just trading volume. For asset owners, what matters is portfolio performance: realised energy prices, generation profiles, balancing costs, exposure to negative prices and the use of flexibility.
That is why we see an asset not just as a source of energy, but as a market position that needs professional management, monitoring and optimisation.
03
Technology, overseen by experts
We use market data, weather forecasts and analytical tools to support trading and operational decisions. We automate repetitive processes where this improves speed, quality and consistency.
Technology does not replace expert accountability. It is a supporting layer for a team that understands the market, the assets, settlement and risk.
Team
Experience across energy markets, trading, technology and strategy
The Aarx team brings together expertise in energy trading, portfolio management, market operations, technology, business transformation and energy project development.
Our model is backed by people who understand both the realities of the wholesale market and the operational challenges faced by asset owners. This allows us to combine the market, technology, process and risk perspectives in one team.
