As battery and hybrid PV projects grow more complex, SUNCATCHER Engineering uses Gridcog to deliver bankable modelling for utility-scale storage projects across Germany and Poland.
As utility-scale battery energy storage systems and hybrid renewable projects become more complex, proving bankability has become as critical as engineering the asset itself. Dynamic power markets, evolving subsidy frameworks, and multiple battery revenue streams now require sophisticated and transparent analysis.
Gridcog is an energy modelling and optimisation platform that helps developers, EPCs, investors, and lenders quantify value and risk across batteries, renewables, and hybrid energy systems. SUNCATCHER Engineering uses Gridcog to deliver financing-ready insights for utility-scale battery and PV projects across Germany and Poland.
SUNCATCHER Engineering
As part of the wider SUNCATCHER Group, which operates as a project developer and Independent Power Producer, SUNCATCHER Engineering focuses on constructing battery energy storage systems as an EPC. The team delivers both standalone BESS projects and systems co-located with PV or wind for SUNCATCHER’s own developments as well as third-party customers.
Given increasing uncertainty around battery business cases, SUNCATCHER Engineering relies on Gridcog to model, optimise, and validate the financial viability of complex energy projects before construction and during financing discussions.
“Modelling and evaluating battery and hybrid projects in Gridcog has become central to how we assess value and risk,” says Lucas Dziadek, Project Manager at SUNCATCHER Engineering. “Especially for batteries co-located with PV. It allows us to deliver detailed and credible outputs that banks trust.”
From Feed-in Tariffs to Market Complexity
Renewable energy modelling in Germany has changed significantly. Stable feed-in tariffs once made revenue forecasting straightforward. Today, reduced subsidy certainty, dynamic price curves, and new battery revenue streams have increased analytical complexity.
“The regulatory framework in Germany has become much more complex,” says Lucas. “Batteries introduce new constraints and opportunities, and that requires a much more sophisticated modelling approach, particularly when bankability is critical.”
Modelling Utility-Scale Battery and Hybrid Projects
SUNCATCHER Engineering uses Gridcog to model projects ranging from standalone BESS to complex hybrid systems combining PV, wind, battery storage, and grid charging rights.
One milestone project includes a 55 MWh battery system co-located with an existing operational solar plant in Germany. Despite financing challenges caused by uncertainty around grid charging rights, in-depth Gridcog analysis enabled the project to move forward. Installation is scheduled for mid-2026.
In Germany and Poland, the team also models highly complex systems that combine multiple generation technologies and market participation strategies within a single asset.
Bankable Outputs for Financing
Gridcog outputs form the foundation of many financial cases. Customers often take the simulation results directly to banks, and SUNCATCHER Engineering supports discussions by explaining assumptions, scenarios, and risks.
Different banks require different price curves and sensitivities. Gridcog allows the team to run alternative scenarios quickly and respond to lender-specific requirements. Reports can also be produced in German, strengthening credibility with local institutions.
Efficiency as Demand Accelerates
Demand for utility-scale batteries is rising rapidly. In one recent month, SUNCATCHER Engineering modelled seven utility-scale projects in Gridcog, with volumes expected to increase. A small specialist team delivers fast analysis, supported by close collaboration with the Gridcog support team.
Why Gridcog
Gridcog combines ease of use with a high level of technical detail. Regulatory constraints, subsidy schemes, PPAs, grid charging rights, and multiple market scenarios can be modelled within a single framework.
“No matter how complex a project is, we have always found a way to model it in Gridcog,” says Lucas.
Scaling Across Germany and Poland
Looking ahead, the SUNCATCHER Group plans to start construction of around 500 MWp of PV in 2026 across Germany and Poland, with all projects expected to include battery storage. SUNCATCHER Engineering also plans to construct 150 to 200 MWh of BESS systems for customers in 2026.
“Gridcog helps us choose the right system sizes, understand the economics, and de-risk projects before construction,” Lucas concludes.
