Who Nortrafo serves, in a nutshell
Nortrafo AS manufactures distribution and medium‑power transformers for utilities, industry, and commercial infrastructure. Think the quiet gear that turns high‑voltage supply into the usable voltages that keep campuses, data halls and municipal loads humming.
What went live
EC3 shows Nortrafo’s first EPDs landing in December 2025. The declarations cover oil‑immersed, medium‑power distribution transformers at common kVA ratings and voltages used across Nordic grids. The program operator is The Norwegian EPD Foundation, and the EPDs were produced using the LCA.no toolset with verification per EN 15804 and EN 50693 (EPD‑Norge, 2025). In the EPDs, the functional unit is one oil‑immersed transformer with a 35‑year reference service life, consistent with the transformer‑specific PCR used in the study (EPD‑Norge, 2025).
For buyers, that means credible, product‑specific numbers they can plug straight into project calculators instead of defaulting to conservative estimates that penalize products without enviromental proof.
Scope and coverage at a glance
Nortrafo’s EPD set spans multiple transformer sizes from 100 kVA up to 1250 kVA at 11 kV and 22 kV, which maps closely to what utilities and developers specify for secondary substations and campus distribution. Several of these are already visible on EPD‑Norge’s directory, with PDFs downloadable by rating and voltage class (EPD‑Norge, 2025). One example EPD lists 27 June 2025 as the issue date and 27 June 2030 as the validity end, and documents LCA modeling via LCA.no with the transformer PCR Part B for transformers (EPD‑Norge, 2025). Nortrafo’s own 2024 Sustainability Report also flagged the plan to expand EPD coverage across core distribution ratings, with seven EPDs reported by September 2025 (Nortrafo Sustainability Report, 2025).

Program operator and rulebook
The declarations are published with EPD Norway, following ISO 14025, EN 15804 A2, and EN 50693, with EPD Italy Part A and Part B for transformers referenced in the documentation for method consistency (EPD‑Norge, 2025). That matters because spec teams compare like for like. A good PCR is the Monopoly rulebook of LCAs, ignore it and the game falls apart.
Competitive snapshot
- ABB appears in EC3 with current EPD coverage for low‑voltage dry‑type distribution transformers under the PEP system, which is a different slice of the transformer market but still relevant in specs.
- As of March 20, 2026, EC3 shows limited or no current transformer‑specific EPDs from Siemens or Hitachi Energy. Both have EPDs for other electrical categories, yet not the medium‑power distribution transformers that compete head to head with Nortrafo in many utility and campus projects.
Net effect, Nortrafo has entered the transparency arena in a category where many global names are still light on product‑specific transformer EPDs in EC3. That helps level the playing field on technical merit instead of price alone when EPDs are requested.
Where to find the documents
The PDFs are available on EPD‑Norge’s directory by rating and voltage. We did not find a dedicated EPD download page on nortrafo.no at the time of writing. Visibility is key, so adding a simple documentation page that links each EPD by rating tends to pay off fast in pre‑bid screening.
Why this is commercially useful
On projects tracking LEED v5 and public buyer criteria, a product‑specific EPD avoids fallback factors that add a quiet penalty in carbon accounting. That improves Nortrafo’s chance to stay specified once shortlisted. It also lets sales teams answer the “send us the EPD” email in minutes, not days, which keeps momentum in bids.
Timing tip many teams miss
There is often a delay of weeks to months between an EPD being issued by a program operator and it appearing in the global directories specifiers use. If the goal is to have new EPDs discoverable within a day or two next time, reach out and we can share the exact playbook for faster listings.
The takeaway
Nortrafo just made the jump from claims to proof in transformers. Publishing product‑specific EPDs across real‑world ratings with a reputable operator puts them in more bids with fewer trade‑offs. The smartest move now is simple, make the documents easy to find and keep the momentum by expanding to any remaining high‑runner SKUs.
