Founders: Fabian Le Gay Brereton and Pete Tickler

Gridcog, an energy-modelling platform based in Sydney that helps developers and businesses simulate complex renewable projects spanning solar, wind, battery storage and flexible demand, has raised $12.5 million in an oversubscribed Series A. The round was led by ABB Electrification Ventures, with participation from Axpo Ventures, DNV Ventures and Verbund Ventures. It follows a $6.4 million raise in 2024.

Founded by Fabian Le Gay Brereton and Pete Tickler, Gridcog replaces slow, error-prone spreadsheet modelling with transparent simulations that cover generation, grid constraints, tariffs, market participation, and project finances.

The company targets four distinct buyer segments, each with its own tailored pitch: large-scale asset developers (utility-scale solar, wind, battery), e-mobility fleet and EV charging operators, consultants modelling projects for clients, and energy majors' internal analysis teams. Named customers span all four — Shell, TotalEnergies, AGL, FRV, ACEN, EY, PwC, Connected Energy, GoldenPeaks Capital, NewVolt and Volta Energy Group.

The core pain is that energy analysts model complex projects in "big, messy spreadsheets" that are slow, error-prone, and break down as teams grow. Gridcog replaces those with transparent, fast simulation software that handles the physical and commercial complexity — multiple markets, sites, and assets at once.

The capital funds further technology development and the expansion of Gridcog's product, customer and commercial teams across Australia, the UK and Europe — a signal the company is chasing the energy transition wherever the modelling problem exists.
