Earnings, deals and disclosures from Japan's listed energy & utilities companies, in English.
Renova has contracted all output of its 54.6MW Kumamoto wind project to Tokyo Gas for 25 years at above the feed-in tariff, though the price is undisclosed and the plant is not yet running.
Hokkaido Electric Power says the Tomari seawall will cost ¥125.5bn and still finish in August 2027, with schedule pressure from overlapping safety works in a cramped site and no earnings impact yet disclosed.
Kansai Electric's Kanto Hapi e Plus basic charge goes to ¥1,071.65 from ¥830.72 for contracts of 6kW or less on November 1, while its per-kWh rates move only slightly, in line with revised wheeling terms.
Shikoku Electric will raise all low-voltage plans from 1 November to pass on higher wheeling charges, with sample household bills up ¥478 to ¥777 a month and an earnings effect it expects to track the grid arm's ¥23.9bn annual gain.
Kansai Electric's modeled low-voltage bills rise 4.3% to 6.9% from 1 November as revised grid charges pass through, while sample high-voltage users on the current standard menu see 2.3% to 2.9% and extra-high-voltage examples 0.5%.
Tohoku Electric will raise electricity rates for every customer class from November 1, adding ¥485 a month to a typical household bill and around ¥17,000 to an office or commercial building's, as its grid subsidiary's revised wheeling charges take effect the same day. The company expects the change to improve group earnings by roughly ¥30bn this fiscal year, but has not folded that into full-year guidance.
Hokkaido Electric is raising regulated and liberalized electricity tariffs from November 1, lifting a standard household bill from ¥11,115 to ¥11,596 as it passes through a higher grid-usage fee set by the region's grid operator.
Shikoku Electric Power Transmission & Distribution will lift wheeling charges across every voltage class from November 1, adding a net ¥33.8bn to projected revenue over two years, but the parent utility still has not decided how much of that increase reaches retail electricity bills.
Kansai Transmission and Distribution's METI filing raises wheeling tariffs at every voltage level from November 1, with low-voltage connections taking the biggest hit, up ¥1.22 to ¥9.04 per kWh, a cost retail electricity suppliers pay before any pass-through to customer bills is decided.
METI has approved a revised wheeling-charge revenue forecast for Shikoku Electric Power Transmission & Distribution, with new unit prices due from November 2026, but the parent still hasn't decided whether the revision will reach retail electricity bills.
Kansai Electric will overhaul extra-high-voltage and high-voltage rate menus from November 1, citing inflation and rising capacity and non-fossil-certificate costs, and its own bill examples show the largest industrial users facing increases of about ¥22.22mn a month, a figure that excludes a separate, still-unpublished transmission-fee revision due the same day.
Okinawa Electric Power wants Japan's industry ministry to lift its five-year grid-wheeling revenue cap by ¥15.7bn to ¥362.1bn, blaming inflation and interest costs its 2023 plan never priced in, with new rates targeted for November 2026 pending approval.
