GreenEdge: Best in BESS - ENG

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.

04 - UC84 - Poland's New Grid Connection Rules

On April 15, 2026, Poland published UC84 in the Journal of Laws — a comprehensive amendment to the Energy Law that fundamentally changes how grid connections work. The law enters into force on April 29, 2026. After almost a year of legislative work, numerous controversies, and Senate amendments, we have the final text. Time to explain what changed and what it means for BESS and renewable energy investors and developers. In this episode: grid connection conditions validity shortened from two years to one and what this means for the development process; three new financial instruments — application fee, doubled advance payment, and an entirely new security deposit — with specific amounts; milestones in connection agreements and the force majeure clauses the Senate introduced at the last moment; two new types of connection agreements — why flexible and configurable agreements are two completely different things and why banks won't finance your full capacity under the latter; cable pooling extended to energy storage — the change the market has been waiting for; and retroactivity — the most controversial element of the law and the specific compromise that ultimately made it into the final text.
