This European data centre operator already reported 100% renewable electricity on an annual basis, but the bigger question was hourly: how clean is our power in each hour, and what carbon impact do our PPAs deliver?
With rapid expansion, rising customer scrutiny, and evolving EU reporting expectations, the team needed a scalable way to track performance across sites and contracts — without relying on annual averages.
Assess how electricity use matched renewable energy procurement hour by hour.
Why this mattered
Energy is a major operating cost (around 40% of OPEX in many data centres)
Rapid expansion increased the need for consistent data across sites and meters
PPAs needed ongoing performance checks, not just annual settlement
Pressure from evolving EU rules (CSRD, GHG Protocol, Energy Efficiency Directive)
National recognition increased the need for transparent reporting.
The operator used Renewabl Track to align site-level consumption with PPA profiles and grid data, then calculate an hourly Carbon-Free Energy (CFE) score and emissions abated.
This gave a live view of when demand was matched with renewables, the PPA generation excess and unmatched hours, and whether contracted supply delivered the expected carbon impact.
