₩300 ceiling, KEPCO bill rising: South Korea's EV-charging operator squeeze.
In May 2025 Hanwha sold its 16,000 EV chargers to a smaller rival and walked out of the business. Two weeks earlier LG Electronics shut its EV-charger factory after three years. SK Networks is selling its SK Elec-link stake to a Hong Kong private-equity firm. A Seoul downtown operator missed an electricity bill and entered closure in March. The Ministry of Environment (the regulator that sets prices at public chargers) has frozen the per-kilowatt-hour tariff for three years running, while KEPCO — Korea's state electricity utility — has raised both wholesale rates and demand charges. The ceiling is national; the costs are not.
01The pain
In May 2025 Hanwha sold its 16,000 EV chargers and walked out of the business.1 Two weeks earlier LG Electronics had shut its EV-charger factory after three years. By autumn SK Networks was selling its stake in SK Elec-link to a Hong Kong private-equity firm. In March a Seoul downtown operator missed an electricity bill and entered closure.2
The squeeze is mathematical. South Korea's Ministry of Environment (the regulator that sets prices at public chargers) has frozen the per-kilowatt-hour tariff for three years running. KEPCO, the state electricity utility, has raised both wholesale rates and demand charges (a fixed monthly fee tied to peak power draw). A state automotive research institute reports that a single fast charger now earns about ₩1.5 million a month in revenue and only ₩200,000 in net profit after power and maintenance. Slow chargers (the 7-kilowatt overnight units) are mostly loss-making.3
Small operators (parking-lot owners and shopkeepers running two to fifty chargers) fare worst. A Seoul city operator collects the same ₩300 per kilowatt-hour as a rural one but pays four times the rent. The ceiling is national. The costs are not.4

02Who solves this today
Four global EV-charging operator software vendors whose homepages publicly market the closest published products to the Korean operator's revenue-and-energy-cost problem — charge-point management systems with billing, time-of-use tariff handling, energy-management modules, and corporate-fleet flows. The narrowness of the list is itself the wedge: none of the four is yet localised to South Korea, integrates with KEPCO's tariff API, or sells to the 2–50-charger SMB operator running on a Korean shopping-mall basement floor. Each entry was checked live on the date of writing.
Listed providers publicly market CPO-management, energy-management or charge-point-billing software on their own homepages. Inclusion is not endorsement. The four entries above are the subset of the global CPO-software catalogue whose self-marketing is closest to the Korean operator's tariff-freeze-plus-rising-electricity problem; the gap they leave — no Korea-localised product, no KEPCO time-of-use tariff integration, no SMB-CPO-on-a-shopping-mall-basement go-to-market — is the wedge described in section 01. Probed and dropped at the date of writing: Etrel and GreenFlux (acquired into larger groups, current public homepages emphasise hardware or roaming rather than the revenue-optimisation surface this page is about); ChargeLab (Canadian CPO software, valid adjacency but homepage emphasises North-American utility programs rather than the Asia tariff problem); EV.Energy (consumer-side smart-charging app, not a CPO operator platform); Pluglink, SK Elec-link, Hanwha Motive (referenced in section 01 as the Korean operators undergoing consolidation, not listed as solution providers); the Korea Automotive Technology Institute, PwC Korea, Electric Times and Daum are referenced as media and research citations rather than listed as solution providers.
