Why now
Now it's your turn
This used to be a large-company problem. Now, for large buyers to hit their own RE100 targets, they have to ask it of their suppliers — and that request shows up in the annual scorecard.

Case 01 / 03
Volvo: "Make every part with renewable power" — a supplier that couldn't comply lost the contract
A Korean parts supplier that could not meet the requirement to produce with renewable energy only by 2025 lost a contract at the final stage.
K-RE100 isn't a cost — it's how you protect your revenue.
What we hear
The three biggest blockers companies hit with K-RE100
The concerns we heard most often interviewing 80 Korean suppliers over the last six months.
Manufacturing · production lineProcurement team, Mr. Kim
We've been told to do RE100, and we don't even know where to start
We received the buyer's requirement, but we don't know where to begin given our size and situation. We don't have anyone dedicated to this.
Electronic componentsESG lead, Ms. Lee
We have no way to tell if a quote is fair
Comparing PPA, REC and green premium quotes means contacting five to ten suppliers ourselves. We still have no basis to tell whether what we're quoted is expensive or cheap.
Semiconductor componentsFinance team, Mr. Park
One wrong contract and we're afraid of the penalty
RE100 contracts run ten years or more, at a large scale. We have seen cases where the cost of exiting a bad contract outran the margin on the underlying business.

Why us
Why OpenEnergy?
We run it end to end
From diagnosis to design, procurement and execution — the full process, so your team doesn't have to chase it themselves. You don't need an in-house specialist.
We read the pricing
The same PPA prices very differently by generation time block. Because we came from KEPCO, we know how the price is actually set — and we check whether it is fair before you sign.
We prove it with numbers
We apply KEPCO's actual tariff rules — contract capacity, power factor, the 30% floor — to work out your cost in verified numbers, not guesswork.
