Turning natural resources into practical energy solutions

Off Grid Energy offers a reliable and sustainable energy option for water production, enhancing energy security and ensuring access to clean water under most conditions.

  • Vertical wind turbine on a concrete foundation on a rocky Norwegian coastline, producing off-grid wind powe

    Wind power

    Vertical wind turbines – local wind power
    Capture wind from any direction and integrate with solar, batteries and backup generators.

    Output example: An average 3 kW over 24 hours delivers 72 kWh per day. Actual output depends on turbine model, wind and installation height.

  • Bifacial solar panels in a snowy Arctic landscape, capturing direct and snow-reflected sunlight

    Solar power

    Solar energy – power from sunlight and daylight
    A 450 W bifacial panel captures direct, diffuse and snow-reflected sunlight. Cold temperatures can improve efficiency, but panels must remain snow-free. Output is minimal or zero during polar night.

    Output example: 1.8 kWh per panel per day with four equivalent full Sun hours, before system losses. Actual output varies by season and location.

  • Kaplan turbine in flowing water, generating hydropower at low water heads

    Hydropower

    Kaplan turbines – power from flowing water
    Kaplan turbines generate electricity at low water heads of 1–40 metres and high flow rates.

    Production example: A turbine delivering 30 kW generates 720 kWh per day during continuous operation. Actual output depends on water head, flow and system efficiency.

  • Compact wood pellet bioenergy unit with fuel hopper, producing local electricity and heat

    Bioenergy

    Bioenergy – local power and heat
    A compact system using wood pellets to generate electricity and useful heat for water, buildings and technical installations.

    Output example: 5 kW of electrical power delivers 120 kWh of electricity per day during continuous operation, plus useful heat.

Reliable power day and night

  • 5 kW methanol fuel cell with methanol tank, providing reliable off-grid and backup power

    Fuel cells

    Methanol fuel cell – reliable local power
    Converts methanol into electricity for off-grid and backup applications.

    Output example: A 5 kW fuel cell delivers 120 kWh per day at continuous full output. Actual production depends on operating conditions and fuel availability.

  • Geothermal power plant in a snowy volcanic landscape, generating electricity day and night

    Geothermal energy

    Geothermal energy – reliable power from the Earth
    Uses heat from deep underground to generate electricity day and night, independently of sun and wind.

    Location: Requires suitable geothermal resources, often found in volcanic regions.

    Applications: Electricity for water production, industry and local energy supply. Output depends on resource temperature, flow and plant design.

  • 20 kW diesel backup generator supplying power for off-grid operation and water production

    Backup generators

    Backup generators – power when needed
    Diesel, petrol or gas generators provide electricity for off-grid operation and backup, supporting water production when other energy sources are insufficient.

    Output example: A 20 kW generator delivers 480 kWh per day at continuous full output. Actual production and fuel consumption depend on load, efficiency and operating conditions.

  • Hybrid energy inputs on a water production unit: separate connections for grid power, solar and wind, and a backup generator

    Hybrid energy inputs

    Hybrid power connection – grid, solar/wind and generator
    Three separate inputs let the water production unit run on grid power, solar and wind, or a backup generator.

    Applications: Keeps local water production going during power outages, extreme weather and technical failures. The energy mix is chosen to suit each site.

Your water network produces electricity

Turning excess pressure in drinking water networks into clean, local energy.

Off Grid Energy & Water AS provides energy recovery solutions for drinking water networks, transforming surplus pressure into renewable electricity while enhancing water security, energy resilience, and emergency preparedness.

Proven international experience

The technology is successfully deployed in drinking water networks worldwide, with installed capacities ranging from 15 kW to 2,626 kW. These installations demonstrate a scalable and reliable approach to generating renewable electricity from existing water infrastructure.

Technology partner and reference supplier: GUGLER Water Turbines GmbH, Austria.

For water supply resilience, site-specific turbines may supply local power to controls and circulation or pumping equipment where hydraulic conditions permit. Operation during a grid outage requires suitable electrical design, protection, controls and, where needed, battery storage and backup power. Required flow, pressure and drinking water quality must be maintained.
