06: Choosing a BESS Supplier

09: The EPC Tender - Selecting the right Contractor

You have your permits, your equipment order, and your grid connection agreement. Now you need someone to actually build the thing. And this is where a lot of projects go wrong — not because of bad technology or poor financing, but because of a contractor selection process that wasn't designed to find the right partner. In this episode I cover the full EPC procurement process from both sides of the table — I've run RFP processes as an investor advisor and prepared bids as a contractor representative. That dual perspective changes what I think actually matters here. In this episode: * Three EPC delivery models — Full EPC, BoP, and Full Wrap with O&M — and what each one means for risk allocation and cost * When to issue your RFP and how to structure the process in phases, from RFI to BAFO * What a well-constructed tender document actually contains — and where most RFPs fail * How many contractors to invite and why a wide-distribution tender produces worse outcomes * The site visit — when to organise it and what it tells you about a contractor before you sign anything * How to evaluate offers beyond price: track record, team, financial stability, contract posture * Red flags on both sides — signals from contractors that something is wrong, and signals from investors that push the best contractors away * How the Polish EPC market compares to Germany and the UK, and what that means for your procurement strategy The cheapest offer is very often the most expensive project.

08: NIS2 and Cybersecurity in BESS Project

On the 19th of February 2026, Poland signed the amended Act on the National Cybersecurity System — the Polish implementation of the EU NIS2 Directive. For BESS investors and developers, this is not an IT compliance story. It's a project risk story, which affects you whether your entity is directly regulated or not. In this episode: why the energy sector — including battery storage — is explicitly covered by NIS2; how flow-down clauses mean NIS2 reaches your project even if you fall below the direct regulation threshold; what a BESS actually looks like as a cybersecurity target — the three system layers and four realistic attack vectors; what the Polish KSC Act requires from you and on what timeline; what to require from each party in your supply chain — BESS supplier, SCADA integrator, EPC contractor, O&M provider, and aggregator; what cybersecurity testing needs to happen before you sign off on commissioning and who should conduct it; which contract clauses lock this in; and why building security into a fifteen-year asset from day one is a fundamentally different calculation than treating it as an optional extra.

07: SGU - Significant Grid User

In September 2025, for the first time in Poland's history, battery energy storage systems were included on the SGU list — Significant Grid Users. If you are developing or financing a BESS project with a capacity of at least 10 MW and 40 MWh — this episode is for you. In this episode: what SGU is and where this obligation comes from; who ends up on the list and how that process works from the investor's and developer's side; what specific technical and operational obligations the SGU status imposes; why there is no compensation for being an SGU and what costs to expect; what grid following, grid forming, and black start mean — and why this decision should be made at the EPC specification stage; whether you can build an off-grid installation and what that means legally for a large BESS project; and why SGU, Poland's grid connection reform, and NIS2 together tell one story — BESS as critical grid infrastructure.

06: Choosing a BESS Supplier

You've developed your project, secured the permits, and now you need to buy the system. And this is where a lot of investors — including experienced ones — discover they weren't as prepared as they thought. The BESS supplier market is crowded, opaque, and the differences between offers that look identical on paper can be enormous in practice. In this episode, I walk through how the supplier market actually works — cell manufacturers, system integrators, technology developers, and why the distinction matters. I cover the structural shift that's making life harder for smaller investors as top-tier suppliers chase volume, how to evaluate supplier credibility before you commit, what scope of supply you should actually be asking for, how to run a proper RFP and BAFO process, what certifications matter specifically for projects in Poland, and the red flags in offers and term sheets that tell you something is wrong before you've signed anything. e-mail: contact@greenedge-solution.com [contact@greenedge-solution.com] www.greenedge-solutions.com [http://www.greenedge-solutions.com/]

05: How to Develop a BESS Project in Poland

Development is where most BESS projects succeed or fail — not on the construction site, but in the eighteen to twenty-four months before a single container arrives. In this episode, I walk you through the full development process for a utility-scale stand-alone project in Poland: site selection, land rights, zoning under the new General Plan regime, environmental decisions, grid connection under the new UC84 rules, building permits, cable route negotiations, and what RTB actually means versus how it's often marketed. UC84 changed the economics of early-stage development significantly — higher upfront deposits, new performance securities, shorter validity periods for connection conditions, and mandatory milestones in connection agreements. The Zoning Conditions system is being replaced by General Plans, which municipalities must adopt by end of August 2026. And cable pooling has finally been extended to battery storage, which opens real opportunities for PV retrofit projects. This episode also addresses the retroactivity provisions of UC84 and what they mean for anyone evaluating a project acquisition, and why remote development of Polish projects without local presence almost always ends in frustration.
