Ust-Kamchatsk is an operating isolated diesel-wind power system, not a battery microgrid. The Japanese-Russian demonstration installed three cold-climate 300 kW Komai wind turbines plus Fuji Electric controls, using controllable electric boilers to absorb excess wind and support district heating. NEDO reported a 7.6% annual diesel reduction—about 400 tonnes—during the demonstration. The current local utility page lists an 18.6 MW diesel station, the three original Komai units, an earlier 275 kW Vergnet turbine and a fourth 300 kW wind turbine installed in 2022. The latest public page does not give current annual wind penetration or confirm the maker of the 2022 unit.

Research status
Operational isolated diesel-wind system. The Japanese demonstration concluded successfully in 2016; the local utility continues to list the wind and diesel assets, including fleet renewal and an additional 300 kW wind unit in 2022.

Project delivery

Who was involved in Ust-Kamchatsk Microgrid?

8 publicly identified organizations. Where a recovered source named a participant without explaining its work, the role remains explicitly unspecified.

Organization

AO Southern Electric Grids of Kamchatka (AO UESK / ЮЭСК)

Current local utility/operator of the Ust-Kamchatsk diesel station, wind assets and local grids. [2][8]

Organization

Fuji Electric

Provided microgrid/grid-stabilization equipment and control integration for the demonstration. [3]

Organization

Komaihaltec

Supplied the KWT300 cold-climate wind turbines and led turbine construction/commissioning work. [3][4]

Organization

Mitsui

Publicly named participant; role not specified in the recovered record [1]

Organization

Mitsui & Co.

Japanese project consortium participant in the NEDO demonstration. [3]

Organization

New Energy and Industrial Technology Development Organization

Japanese public funder and administrator of the 2014-2016 cold-region wind/microgrid demonstration. [3][5][6]

Organization

RAO Energy Systems of the East

Russian demonstration partner/offtaker group working with the Japanese consortium. [3][6]

Organization

Vergnet

Manufacturer of a separate 275 kW wind turbine commissioned before the Japanese three-turbine project. [2]

System evidence

Energy mix, capacity, and specifications

Values can describe different project phases, generation sources, storage systems, or other components. Source citations are attached to each figure so discrepancies remain visible.

KW Wind
900 [1]
Original NEDO wind plant
3 × 300 kW = 0.9 MW — Komai KWT300 cold-climate turbines, completed in December 2015 with demonstration operation beginning January 2016. [3][4]
Other utility-listed wind assets
275 kW Vergnet plus one additional 300 kW turbine installed in 2022 — The current utility page does not name the manufacturer of the 2022 turbine or clearly document final commercial acceptance. If all listed wind units are operating, nominal wind capacity would be 1.475 MW, but that total is an inference rather than an explicit utility figure. [2]
Diesel station installed capacity
18.6 MW — Current utility figure for diesel generation only; do not add it to a separate published station-capacity total without checking whether wind is excluded. [2]
Current diesel fleet
3 × 0.8 MW G-72; 2 × 1.0 MW LB8250ZLD-1; 2 × 1.5 MW Caterpillar D3516; 7 × 1.6 MW Mitsubishi S16R-PTAA2-C — The unit ratings sum to 18.6 MW. The utility says six Mitsubishi sets were prepared for commissioning in 2022 as replacements, while its equipment table lists seven total Mitsubishi units. [2]
Demonstrated diesel savings
7.6% annual reduction, approximately 400 tonnes of diesel per year — NEDO demonstration result/estimate, not a current audited operating-year metric. [5][6]
Battery storage
None documented — The demonstration managed wind variability with controls, diesels and controllable electric-boiler load rather than a reported BESS. [3][7]

Controls and hardware

Equipment and controller details

Manufacturer and model are shown only when a source names them. Generic descriptions are not converted into guessed product assignments.

01

Cold-climate wind turbine

Komaihaltec — KWT300

Quantity/status: Three confirmed in the original NEDO project — Komai's current project-results page displays a quantity of four, conflicting with its original completion release and the utility history, both of which identify three original Japanese-project units. A separate fourth 300 kW turbine was installed in 2022, but its maker is not established by the utility source. [2][3][4]

02

Wind turbine

Vergnet — Not disclosed

Quantity/status: One 275 kW unit — Commissioned in 2014 according to the current utility page. [2]

03

Microgrid/grid stabilization controls

Fuji Electric — Not publicly disclosed

Quantity/status: One integrated system — Coordinates wind generation, diesel operation and controllable electric-boiler demand. No battery was identified. [3][7]

04

Diesel generator fleet

Various, including Caterpillar and Mitsubishi — G-72, LB8250ZLD-1, Caterpillar D3516 and Mitsubishi S16R-PTAA2-C

Quantity/status: Fourteen units listed, 18.6 MW total — The utility's fleet table is the best current equipment inventory found, though not all units' operating condition or dispatch availability is stated. [2]

Technical record

Architecture, performance, and project updates

Concise technical facts, milestones, operating results, and later developments. Dated notes distinguish historical design claims from current evidence.

  • General

    The installation is located in an isolated township of Ust-Kamchatsk and consists of three 300-kW turbines and a grid stabilisation system — electric boilers for using excess capacity. [1]

  • Control approach

    Wind is integrated into a weak isolated diesel grid through a microgrid control system. When wind output exceeds immediate electrical demand or threatens stable diesel loading, controllable electric boilers convert excess electricity to useful heat. This provides a flexible load and fuel displacement without a disclosed battery. [3][7]

  • Demonstration timeline and outcome

    NEDO selected the project in August 2014; construction began in October, three 300 kW turbines and control equipment were completed by December 2015, and demonstration operation began in January 2016. The demonstration concluded in October 2016 with reported annualized diesel savings of roughly 400 tonnes/7.6%. [3][5][6]

  • Current system context

    The local utility says the diesel station and wind plants serve Ust-Kamchatsk and the Pogodny microdistrict over approximately 108.36 km of lines. Diesel capacity greatly exceeds wind nameplate, so the system remains diesel-dominant even though current annual MWh shares are not published. [2]

  • Capacity conflict

    Komai's results page says four KWT300 units, while Komai's original project release and utility history identify three original Komai units. The utility separately reports a fourth 0.3 MW turbine installed in 2022 without naming its maker. The defensible inventory is therefore three confirmed KWT300s plus one manufacturer-unconfirmed 2022 unit, not four confirmed KWT300s. [2][3][4]
