Building a Bankable PV + BESS Portfolio - from project selection to debt drawdown.

We transformed a 15-project portfolio for a Hungarian PV + BESS developer into a bankable investment pipeline and managed the financing process end to end — from selecting the right projects through acquisition and development to the drawdown of EUR 32m in debt financing.

Context

Our client is an independent Hungarian PV + BESS developer and investor, running multiple projects in parallel with a lean, agile team. Its growth depends on the ability to select, structure and finance projects quickly, while capturing both market-based and state-supported revenue streams (METÁR/METÁROLÓ, Hungary’s renewable-energy support schemes).

The objective was to build a scalable, bankable project portfolio across the full lifecycle, from development to exit. This required a partner capable of supporting each project from initial selection through to financing drawdown.

Our Approach

We supported the client across the full investment lifecycle, through six key milestones, with a consistent focus on bankability:

  1. Project selection - decision support in selecting which projects to acquire.
  2. Acquisition transaction - support throughout acquisition negotiations and financing advisory.
  3. Construction (RTB projects) - arranging financing and running a competitive lender process, leading bank negotiations, and supporting the aggregator tender and contracting process. (RTB = ready-to-build project)
  4. Debt drawdown - end-to-end management of the disbursement process and fulfilment of conditions precedent (CPs).
  5. Performance monitoring and operations - design and operation of a controlling system across four project SPVs.
  6. Exit - support in preparation for the sale of the holding company and preparing the next steps.

Results

Our client received an integrated, bankable investment structure and the financing required for the full 15-project portfolio. Based on the financial and operating plans, we secured competitive financing terms and managed the process to eventual disbursement.
