M&A / Transaction Advisory
Buy-side technical advisory throughout the transaction lifecycle.
We are not one more M&A advisor. Our practice puts energy-transition engineers and transaction specialists in a single deal team: we do not just model financial metrics, we simulate battery degradation, round-trip efficiency, grid-connection capacity and revenue stacks before structuring the transaction. Technical viability first, then the deal.
Technical viability first, then the deal.
One Hub Energy is a Spanish advisory and technology group focused exclusively on renewable energy and battery storage. Our M&A practice integrates energy-transition engineers with transaction specialists in a single deal team.
We do not just model financial metrics. We simulate battery degradation, round-trip efficiency, grid-connection capacity and revenue stacks before structuring the transaction.

Accumulated by our founders, board and senior advisors before One Hub Energy.
Engineers, data scientists, developers, lawyers and transaction specialists in a single firm.
Finance, technical and digital tools working the same mandate.
The problems we get called for.
Sellers present optimistic numbers, and you have weeks, not months, to validate them.
Generalist advisors miss the BESS-specific value drivers: degradation, dispatch strategy and market saturation.
Technical red flags that surface after the offer become your negotiation problem, or your loss.
If any of these are costing you time or money, keep reading.
What you get with us that you won't get elsewhere.
Deal-tested, senior-led
107 mandates delivered for funds, IPPs and developers across Iberia, the UK and Europe. The people who review your deal have closed deals.
Technical + commercial, one roof
We review the asset, the financial model and the contracts as one integrated exercise, no gaps between advisors.
Engagement that fits the deal
Framework agreement or one-off mandate, scoped to the transaction. We move at deal speed.
Every transaction is stress-tested with One Hub Analytics: hourly dispatch simulation and degradation-adjusted revenue projections your investment committee can actually defend.
Most M&A advisors bring one leg. We bring three.
A generalist transaction team can price a deal. It cannot tell you whether the asset behind it will perform, or whether the grid connection holds. We do not just model financial metrics: we simulate degradation, round-trip efficiency, grid capacity and the revenue stack before structuring the transaction. Technical viability first, then the deal.
