About MEXT
MEXT is a leading industrial transformation center established by the Turkish Employers’ Association of Metal Industries. With its advanced digital factory, training and assessment programs, and strong global ecosystem of technology partners, MEXT supports manufacturing companies in accelerating their digital and green transformation journeys across Türkiye and the wider region.
This month, we completed a Proof of Concept (POC) study with MEXT, using their 2024 hourly electricity consumption data. The goal was to understand how precise, time-based carbon accounting can improve emissions accuracy and inform better renewable energy procurement decisions.
Hourly Emission Accounting improved data precision, showing that actual emissions are 22% lower than traditional estimates.
Most organizations still calculate electricity-related Scope 2 emissions using annual grid average emission factors. While widely used, this method masks fluctuations in the grid’s carbon intensity throughout the day. As a result, emissions are often overestimated.
Using Voltfox, we recalculated MEXT’s emissions on an hourly basis. This approach captures the real-time carbon intensity of the grid.
| Calculation Method | Reported Emissions | |
| Traditional Annual Average Method | ~650 tCO₂e | %22 higher |
| Voltfox Hourly Carbon Accounting | ~530 tCO₂e |
This means that MEXT is able to report actual consumption profiles which are significantly lower compared to the results obtained through traditional methods.. By using high-resolution carbon data, a clearer and more realistic picture of their carbon footprint emerged.
Key Value: More accurate reporting → Stronger climate claims → Reduced compliance & audit risk.
Renewable Matching Analysis: 72% Hourly Carbon-Free Energy Possible with Geothermal
Next, we evaluated how MEXT could match its electricity needs with carbon-free energy sources already available or procurement radar.
We matched MEXT’s hourly consumption with the hourly production profiles of three renewable energy facilities:
| Facility | Hourly Match Potential |
| Solar Site | 54% coverage |
| Wind Site | 55% coverage |
| Geothermal Site | 72% coverage ✅ |
This shows that by prioritizing procurement from a Geothermal Site and adopting an hourly matching strategy, MEXT could operate on carbon-free electricity for 72% of the year on an hourly basis without increasing energy consumption or changing operations.
Why This Matters
- Regulatory pressure and GHG Protocol updates are moving toward hourly and granular accounting.
- Investors and auditors are increasingly focused on carbon data integrity, not annual averages.
Renewable procurement is shifting from “how much renewable energy is purchased” → to “when the renewable energy is consumed.”
