The 3 Biggest Profit Killers in Arbitrage Projects
Arbitrage projects can be very profitable – yet even small mistakes can significantly reduce profits. In this article, we take a look at the three biggest profit killers and show how to avoid them.
Navigating regulation
Many storage and arbitrage projects stall because developers must interpret overlapping rules on grid access, planning, environmental permits, and market participation, often across several authorities. Fragmented or changing regulation creates uncertainty around revenue models and grid charges, which makes investment decisions slower and financing more difficult.
For most battery arbitrage projects, the real bottleneck is not the hardware, but the paperwork. Regulations for grid connection, market participation and environmental approvals are complex and often inconsistent across regions. This creates uncertainty, slows down decisions and can turn an attractive business case into a risky bet. Our role as a specialist partner is to translate these rules into a clear roadmap, so you know exactly which permits you need, in what order, and how they impact your project’s profitability.
Time to get on the grid
TSOs and DSOs across Europe, including Germany, are dealing with record volumes of BESS connection requests, which leads to long queues and unclear timelines. Every extra month in the queue adds development costs, delays revenue, and increases exposure to changing market conditions or policy shifts.
Even the best arbitrage strategy is worthless if your asset is stuck in the grid queue. Today, grid operators face an unprecedented number of storage applications, and many projects wait years for a firm connection date. During that time, you carry project costs but generate no revenue. By optimizing siting, preparing grid-compliant documentation early, and engaging proactively with the network operator, we help shorten critical-path milestones and bring your project online faster.
Hidden costs and ‘what if we get it wrong?
Beyond the battery system itself, projects face significant “soft” and hidden costs for permitting, interconnection, grid charges, civil works, compliance studies, and engineering changes. Design or assumption errors can trigger redesigns, change orders, or new studies, which quickly eat into margins and may break financing covenants.
In many arbitrage projects, the costs that hurt most are the ones nobody saw coming: grid fees, additional studies, fire protection requirements, civil works, or redesigns after a late-stage grid comment. These hidden items can easily add mid- to high six figures to a project budget and push IRR below investor expectations. We use structured cost modelling and scenario analysis to surface these risks upfront, quantify them, and design them out wherever possible—before they become expensive surprises.
If you are planning a battery arbitrage project and want clarity on regulation, grid timelines and hidden costs, let’s talk. In a short workshop, we map your specific project against these three risk areas, highlight the biggest cost and delay drivers, and outline concrete steps to de-risk the business case.
