Glencore's off-grid Raglan Mine in Nunavik operates a diesel-wind-storage smartgrid developed with TUGLIQ. Raglan I (2014) added one 3 MW Enercon E-82 E4 turbine and a three-tier store: 200 kW/1.5 kWh KTSI flywheel, 200 kW/250 kWh Electrovaya lithium battery, and a Hydrogenics loop with a 315 kW electrolyzer, 198–200 kW PEM fuel cell, and roughly 1–4 MWh hydrogen-storage figures depending accounting. Raglan II (2018) added a second 3 MW wind turbine and a 3 MW/1.64 MWh Saft Intensium Max+ 20M G2 battery (TUGLIQ rounds it to 1 MWh). Diesel remains the backbone of the isolated mine grid.

Research status
The two turbines and storage systems are operating. Glencore's 2024 engagement report says they supplied around 10% of total mine energy and saved more than 4.7 million litres of diesel and 13,000 tonnes CO2e in 2024—better than 2023. A proposed wind farm is not yet installed: Glencore was assessing up to 12 near-term turbines subject to impact review and financial approval, while the environmental filing describes a possible phased maximum of 30 additional 3 MW turbines plus new 10 MW/10 MWh storage for the first 12. As of the latest public review page, that expansion remained in environmental procedure and must not be counted as operating capacity.

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

Glencore Canada / Raglan Mine

Mine owner/operator, isolated-grid and diesel-plant operator, host/offtaker, and proponent of the proposed wind-farm expansion. [10][11]

Hatch

Engineering partner and co-developer of the wind-diesel-storage microgrid controller/integration design. [7][9]

Organization

Natural Resources Canada

Federal ecoENERGY Innovation Initiative and Energy Innovation Program funder/publisher for Raglan I and Raglan 2.0. [5][8]

Supplier of the Raglan II 3 MW/1.64 MWh cold-climate lithium-ion BESS. [7]

Organization

TUGLIQ Energy Corp.

Developer, owner, and operator of Raglan I/II wind and storage assets under a 20-year PPA with Glencore; lead proponent for the federally supported Raglan 2.0 phase. [4][6][8]

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.

Operating wind
6 MW total from two 3 MW Enercon E-82 E4 Arctic-rated turbines, commissioned in 2014 and 2018. [5][6][10]
Raglan I storage
200 kW/1.5 kWh KTSI flywheel; 200 kW/250 kWh Electrovaya lithium-ion battery; Hydrogenics HySTAT 60 315 kW electrolyzer and HyPM-XR 198 kW PEM fuel cell. Saft's later overview calls the small battery 250 kW, while the detailed completion report and TUGLIQ page use 200 kW. The completion report calls the hydrogen system 200 kW/1 MWh while TUGLIQ's current page labels the hydrogen cylinder 200 kW/4 MWh, likely different power and stored-chemical/usable-energy boundaries. [5][4][7]
Raglan II battery
Saft Intensium Max+ 20M G2 at 3 MW/1.64 MWh in Saft's detailed case study (about 33 minutes at rated output). TUGLIQ rounds it to 3 MW/1 MWh. These are conflicting/rounded descriptions of the same installation, not two batteries. [7][6]
Mine demand and diesel fleet
Saft reports 14–18 MW round-the-clock electrical demand. NRCan says the upgraded operating philosophy coordinates more than 11 diesel engines. Public current sources do not provide each engine's make, MW, fuel curve, or total firm nameplate. [7][8]
Actual 2024 performance
More than 4.7 million litres of diesel and 13,000 tonnes CO2e avoided by the two turbines, up from more than 3.8 million litres and 10,700 tonnes in 2023. Glencore says wind provided around 10% of total mine energy. [10]
Renewable-penetration definitions
TUGLIQ/Saft cite close to 40% wind penetration in relevant electrical operating intervals, while Glencore reports about 10% of total mine energy annually. These are not contradictory if one is instantaneous/electric penetration and the other includes annual electricity, heat, and/or broader fuel energy. [6][7][10]
Proposed expansion—not installed
Environmental filing: up to 30 additional 3 MW Enercon E-82 turbines (90 MW), phased; first 12 accompanied by 10 MW/10 MWh lithium storage and a new 35 kV production network. Glencore's 2024 public-facing plan discusses up to 12 turbines, 42% renewable electricity, 154 GWh/year, 16.4 million litres/year diesel savings, and 45,000 tCO2e/year by 2029, all conditional projections. [11][10]

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.

  • Three-tier storage control

    The flywheel absorbs fastest transients, the small lithium battery bridges short wind losses and allows generator/fuel-cell starts, and the hydrogen loop captures longer surplus periods. The controller coordinates them with diesel spinning reserve. [5][9]

  • Measured smoothing

    The Raglan I completion report shows a five-minute event where storage reduced a wind-output drop rate from about 130 kW/s to 11 kW/s, demonstrating ride-through and reduced stress on diesel assets. [5]

  • Availability evidence

    The initial Raglan I reporting period achieved 97.3% wind-turbine availability and cumulative displacement of 3.4 million litres of diesel/9,110 tonnes GHG at the report date; current 2024 annual results provide the stronger recent performance benchmark. [5][10]

  • Raglan II function

    The larger Saft BESS provides ramp-rate control, bridging, frequency support, and grid stability for sudden 3–6 MW wind losses. Saft estimates that without storage about 25% of wind output—roughly 2 GWh/year—would need curtailment. [7]

  • Future-grid constraint

    The existing 25 kV network cannot support the proposed wind/storage expansion. The filing therefore proposes a new 35 kV production network while retaining 25 kV distribution to mines and surface facilities. [11]

  • Phase boundary

    Operating nameplate is two turbines (6 MW) plus Raglan I and II stores. The possible 30-turbine/90 MW maximum, first-12 10 MW/10 MWh BESS, 35 kV network, and 2029 savings are proposal-stage and excluded from operating totals. [10][11]
