Tetrino on Russia's Kola Peninsula received an autonomous wind-solar-diesel system in 2015 as part of a Murmansk regional program for roadless White Sea coast villages. The strongest site-specific technical table gives 71.4 kW total: 20 kW wind, 16.2 kW solar PV, and 35.2 kW diesel. Broader project announcements often combine Tetrino with Chavanga, Chapoma, and Pyalitsa and must not be used as Tetrino-only capacity. The project changed local service from roughly eight-to-ten-hour diesel schedules to 24-hour electricity.

Research status
Tetrino's system was commissioned in mid-2015 and contemporary reporting described successful 24-hour operation; a 2017 report said the four-village installations were working well. A 2022 academic review still listed Tetrino among operating autonomous hybrid complexes, but gave generic ratings that conflict with the earlier site-specific table and did not publish Tetrino production or availability. No credible post-2022 Tetrino-specific operating, fuel, outage, or equipment-replacement report was located. Status is historically commissioned and reported operating, with July 2026 performance unverified.

Project delivery

Who was involved in Tetrino – Kola Pennisula?

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

Organization

Government of Murmansk Region

Regional program sponsor and major public funding participant for autonomous renewable-diesel systems on the Tersky coast. [4][5][6]

Organization

Kola Science Centre of the Russian Academy of Sciences

Research institution documenting site-specific capacities, regional energy conditions, and program targets. [4]

Organization

Murmansk regional government

Regional program sponsor and funder [2]

Organization

President-Neva Energy Center

Design and equipment contractor for Tetrino, Chavanga, and Chapoma [3]

Organization

Russian federal, regional, and local budget authorities

Combined public funding sources; the Kola Science Centre paper reports 22% federal, 38% regional, and 3% local funding, with 37% from extra-budgetary sources. [4]

Organization

Tersky District / Varzuga municipal authorities

Local-government host and beneficiary side for village-power modernization; precise long-term ownership and operating assignments were not found in accessible current records. [4][5]

Organization

Varzuga rural settlement administration

Municipal contracting authority [3]

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.

Three-village program demand
515 kW across Tetrino, Chavanga, and Chapoma [2]
Three-village renewable allocation
175 kW wind and solar; approximately 34% of program demand [2]
Generation architecture
Wind, solar PV, and diesel generation [2][3]
Site-specific total capacity
71.4 kW in the Kola Science Centre table, comprising 20 kW wind, 16.2 kW solar, and 35.2 kW diesel. [11][4]
Wind capacity
20 kW site-specific. Public sources do not give a reliable turbine count, manufacturer, model, hub height, or power curve for Tetrino alone. [4]
Solar capacity
16.2 kW site-specific PV. Module and inverter makers/models and current degraded capacity were not located. [4]
Diesel capacity
35.2 kW site-specific in the strongest table. A 2022 review describes these village complexes generically as 60 kW diesel, 20 kW wind, and 15 kW solar; because that appears to be a template rather than Tetrino's as-built schedule, the 35.2 kW site value is preferred and the conflict retained. [4][7]
Service hours
Commissioning changed service from approximately eight-to-ten hours per day from diesel generation to round-the-clock power. [5][6]
Program targets
The regional program targeted roughly 50% reductions in imported fuel/oil and generation cost and a 25% extension of diesel-generator life. These are program targets, not verified Tetrino operating outcomes. [4]
Three-village expansion totals
Project-era reporting described, across multiple villages, ten 10 kW plus four 5 kW wind turbines, about 300 PV modules totaling 75 kW, and multiple diesel sets. These are portfolio totals and are intentionally not assigned to Tetrino. [5][6]
Broader program cost
Contemporary coverage reported approximately EUR 1.5 million for the broader remote-village renewable program, not Tetrino alone. [5]

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

Wind generation

Model not publicly disclosed

Wind equipment totaling 20 kW at Tetrino. Accessible sources do not support a manufacturer, model, turbine count, or per-unit rating. [4]

02

Photovoltaic array

Model not publicly disclosed

PV equipment totaling 16.2 kW at Tetrino. No dependable module or inverter maker/model was found. [4]

03

Diesel generation

Model not publicly disclosed

Diesel capacity totaling 35.2 kW in the site-specific table. Generator count, manufacturer, model, voltage, and prime/standby rating were not found. [4]

04

Control and storage

Model not publicly disclosed

The hybrid complex necessarily includes power conversion and automated dispatch, and regional descriptions refer to renewable-diesel autonomous complexes. No credible Tetrino-specific battery chemistry/capacity, controller maker/model, or one-line diagram was located, so none is invented here. [7][9]

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.

  • Operating architecture

    Wind and PV reduce runtime and fuel use of the isolated diesel plant while diesel supplies firm capacity during low-resource periods. The village remains outside the unified power grid and depends on local generation. [9][5]

  • Portfolio-allocation warning

    Most news releases aggregate equipment and savings across Tetrino, Chavanga, Chapoma, and sometimes Pyalitsa. Only the Kola Science Centre's site row is used for Tetrino capacity; broader figures remain contextual. [4][5][6]

  • Reported regional fuel outcome

    A 2016 industry report says fuel deliveries across the broader village program fell from more than 290 tonnes per year to 143 tonnes in the preceding year. It is not a Tetrino-only measurement and cannot validate the site's 50% target by itself. [8]

  • Early operational evidence

    Commissioning reports document 24-hour service in 2015, and TASS reported in 2017 that the four autonomous village plants were working well and that one plant could save more than RUB 3 million annually. The savings statement is not identified as Tetrino-specific. [5][10]

  • Capacity discrepancy

    The 2022 generic 60 kW diesel/20 kW wind/15 kW PV description totals 95 kW and conflicts with the earlier Tetrino-specific 71.4 kW table. It may describe a standardized configuration or another village; it is not substituted for the site-specific record. [4][7]

  • Current-data gap

    No credible post-2022 source was found for Tetrino-specific generation, diesel consumption, outages, renewable share, maintenance, equipment replacement, or present service hours. The installed system is historically well documented, but 2026 operation is unverified. [7]
