Case studies
During the time of operation Nocart has delivered over 50 working energy solutions globally. Cases vary by source and size, from smaller improvements on existing systems to full scale solutions deploying local energy sources. As of summer 2015 we are witnessing a rapid rise on our order base while numerous orders are being processed and fulfilled.

Finland. Energy self-sufficient farm fueled with biomass.
Kuittila Farm in Nurmes is a dairy farm on 150 cows. Barn, grain and woodchips drying facilities, metal workshop and the main building have annual electricity consumption of approximately 340 000 kWh, and heating consumption of approximately 700 000 kWh. Due to the high consumption it was decided that the farm should be made self-sufficient in both electricity and heating.
Solution
Small power and heat production facility that utilizes wood gasification. Nocart unit is used to generate 45kW on-grid electricity.
Benefits
Self-sufficiency and reliability. The system has also improved the farms fire safety. With the only emission being water vapor the farm doesn’t pollute, which is not only ecological but it also gives the farm great image benefits. In a long run the cost savings are also significant.
Kenya. Energy self-sufficient dairy farm fueled with biogas.
A modern free stall zero grazing unit was built during 2012 for a herd of Holstein Friesian cattle located in Mweiga, Kenya. In free stall design, each cow is accorded individual attention in feeding, monitoring, comfort, proper ventilation and free passage. The unit has a capacity to hold 200 mature cows.
Solution
The unit is run by biogas power plant using cow manure as the energy source.
Benefits
Self-sufficiency and reliability. Nocart system allows surplus electricity to be sold to local electric company through grid.
Finland. Energy self-sufficient grain mill using hydroelectricity.
Pitkäkoski grain mill, located in Kiuruvesi, Central Finland, stands next to an old hydropower plant from the 1930s. The mill itself has been working since the 19th century, and nowadays both the mill and the dam are owned by the current milling entrepreneur.
Solution
There are two separate generators, one able to generate 10 kW when the water level is low, and the larger one used to generate 90 kW when the river is rising. The amount of water flow is adjusted in off-grid mode to achieve balance according to usage. Rapid changes are evened out with the use of an additional battery storage unit.
Benefits
The electricity needs for both the milling facilities and the nearby residence are covered by the system, making the estate self-sufficient in a highly ecological manner. The Nocart Power Management Unit also enables surplus electricity to be fed back to the national grid.
Nepal. Humanitarian organization using solar energy as a backup.
An international humanitarian organisation was in need of a reliable backup energy system for their regional office in Kathmandu, Nepal. Due to the unreliable local grid, the office was already relying on diesel generators, but wanted to reduce fuel consumption.
Solution
The 40 kWp solar modules installed on the rooftop charge the battery bank, and surplus energy is used in real time. At times when modules are unable to maintain production and the battery voltage decreases, the Nocart Power Management Unit automatically starts the diesel generator and makes it as the input source for electricity.
Benefits
The Nocart PMU enables electricity to be fed for local consumption through the grid. While the sun is unavailable and the diesel generator is functioning, it only produces electricity for real-time consumption instead of charging the battery bank, which reduces fuel consumption.
