Korea proposes regional industrial electricity pricing, aims for year-end implementation
On August 26, the Ministry of Climate, Energy and Environment and KEPCO unveiled a design plan for regional industrial electricity pricing, proposing discounts up to 18 KRW/kWh in southern regions. This marks the first change to Korea's 24-year national single-rate system, targeting year-end implementation through tariff revisions.
Our take
Who wins and loses from Korea's proposed regional industrial electricity pricing?
Industrial users outside the demand-heavy southern Seoul Capital Area win and none pay more: the design only grants discounts, up to 18 KRW/kWh in the south, so it pulls new industrial load toward generation-rich regions without charging congested areas, and the estimated KRW 2.8 trillion cut in industrial bills must be absorbed by KEPCO or other customers.
In favour of the signal: it is the first break from a single national tariff in 24 years, rests on the Distributed Energy Act, and needs only a revision of KEPCO's supply terms, which the government targets by year-end. Against: at most about 10% of the average industrial price, the discount is modest, and lawmakers from both main parties question who pays for it, which leaves the size of the discounts open to revision. Whether it is strong enough to move siting decisions depends on the final notice and on how the revenue loss is funded.
What the source says
- The design plan divides the country into 11 regions by combining 4 broad power system zones and 4 balanced growth zones.
- The proposed system adds a 'regional adjustment fee' to existing industrial tariffs without altering the base structure.
- The government aims to finalize the official notice and revise electricity tariff terms by the end of this year.
- Kwak Sang-eon Lawmaker Kwak Sang-eon argued that providing cheaper electricity to specific companies could shift the burden to other businesses and citizens.
- Na Kyung-won Lawmaker Na Kyung-won pointed out that KEPCO's electricity sales revenue might decrease due to lower industrial rates in non-capital regions, necessitating financial countermeasures.
- The government plans to promote 'local production, local consumption' of electricity and reduce the burden of transmission grid construction.
- The regional pricing scheme excludes residential, general-use electricity, and Jeju Island due to its unique power supply characteristics.
- The legal basis for the regional pricing scheme is Article 45 of the Distributed Energy Act, which was implemented in June 2024.
For investors — Manufacturers and other industrial-tariff users: the south now carries a price advantage of up to 18 KRW/kWh over the southern Seoul Capital Area; factor it into siting only once the notice is final, since the discount can still change. Residential and general-use tariffs, and Jeju, are excluded.
Solar, wind and storage investors: the discount applies to the industrial retail tariff, not to generator payments; its effect on generators is indirect, through where new industrial load chooses to locate.
Watch: Finalization of the official notice and revision of Electricity Tariff Terms by the Korean government.
