Shifting the Energy Mix at Scale: 67,000 MTCO2e Avoided Annually
Minute-by-minute asset monitoring combined with active control of generators, rectifiers, and HVAC systems enabled a major telecom operator to dramatically shift its energy mix toward renewables between 2019 and 2022.

Overview
Cutting emissions across a telecom network isn’t just a policy goal, it requires actually changing how thousands of individual sites generate and consume power, day to day, and proving the shift with real operational data.
How Galooli Solved It
From a diesel-heavy energy mix to a network-wide, data-proven shift toward renewables, in four steps.
Diesel-Heavy Network at Scale
24,000+ sites across several regions needed to cut emissions at real network scale without losing uptime.
Minute-by-Minute Monitoring
Galooli captures live data on every onsite asset, network-wide, as the foundation for automated action.
Active Control at Every Site
Automated hybrid-site performance and direct control of rectifiers, generators, and HVAC, AI flags issues.
Measurable Results
Renewables nearly double to 39% of production; 67,000 MTCO2e avoided annually across the network.
Renewable Energy Share
19% → 39%
2019: 19% of production
2022: 39% of production
Diesel Generation Share
38% → 19%
2019: 38% of production
2022: 19% of production
The Challenge
A major telecom operator running more than 24,000 sites across several distinct geographic regions needed to move the needle on emissions at real network scale, not just report on it after the fact, while keeping every site fully operational and heavily reliant on diesel generation as of 2019.
Galooli's Solution
Galooli captured minute-by-minute data on every onsite asset and automated performance at hybrid sites, increasing the uptime and efficiency of solar gensets and micro-wind turbines already in the network. Active control extended directly to rectifiers, generators, and HVAC systems, while the AI Analyst continuously flagged inefficiencies that would otherwise go unnoticed.
Outcomes
Between 2019 and 2022, the energy mix behind the network’s power shifted substantially: renewable energy’s share of production rose from 19% to 39%, while diesel’s share fell from 38% to 19% (the electric grid’s share held roughly steady, moving from 43% to 42%). That shift translated directly into emissions performance: Scope 1 and 2 GHG emissions per tower fell from 17.8 to 15 MTCO2e, and across the full network the operator now avoids a total of 67,000 MTCO2e in emissions annually.
