Project No.: 17VM-KV-14-1-05246-PR001
Project initiation date: 2015 – 06 – 18
Project end date: 2017 – 05 – 22
Financial support allocated to the project: EUR 9,983,650.58
The project is being executed according to the “Rural development programme 2014-2020”, section “Investments into tangible assets – Investment support for agriculture”.
Key aims of the project: modernization investment into partial renovation of a greenhouse complex, installation of innovative technologies in winter greenhouses that reduce energy expenditures and technological energy losses, increase vegetable yield and extend the active operational season of the company to 12 months, by constructing a boiler house using biofuels and gas for heating water. It is expected that the investment will increase the overall efficiency and competitive position of the company, as well as create opportunities for profitable future operations, sustaining workplaces for current employees and creating a platform for potential future expansion.
Expected result: New greenhouse blocks, covering an area of ca. 9.74 ha, with modern technologies for growing vegetables, and a boiler room with capacities of no less than 5MW biofuel and 3MW gas for heating water, with a 1.7 MW cogeneration gas plant and storage tank.
Key features of the new greenhouses:
• Stronger steel beams will be able to withstand larger amounts of snow in winter;
• Two times higher ceilings will allow vegetables (tomatoes and cucumbers) grow extra sprouts, which increases the density of plants per square meter, the vegetables receive better lighting, which directly affects the yield;
• The new greenhouses are more hermetic;
• New window glasses are more permeable to sunlight;
• Ability to install an automated window cleaning line;
• Larger dimensions and stronger beams in the new greenhouses allow using horizontal and vertical heat conservation screens, which effectively reduce energy expenditures (during night time, horizontal and vertical blinds are pulled over the windows)
The equipment installed in greenhouse blocks A, B and C and its traits:
• Energy conserving screens/blinds;
• A system for efficient CO2 distribution in the greenhouse;
• Automated computer system for watering and fertilizing vegetables;
• A system for drainage collection;
• A disinfection system with UV filters;
• Automated computer system for managing the greenhouses;
• An advanced vegetable bed system;
• Equipment for harvesting and transporting the harvested vegetables and taking care of the plants;
• Light reflective cloths for covering the ground;
• An automated window glass cleaning system;
A 5MW capacity biofuel plants (powered by wood chips and residual coconut splint, remaining from the growth process). The plants will allow to significantly reduce the price needed for heating the greenhouses and reduce technological losses in the distribution system.
Together with the 5 MW biofuel boiler, a 3 MW capacity gas powered boiler will be installed, which, together with a co-generation plant would ensure production of heat during months (mostly during July – October), when the heat needs are lower (up to 2,500 MWh per month). The gas boiler would be used together with the biofuel boiler during months (February – April) when due to large fluctuations in temperature (during cold nights) a larger amount of heat is necessary to sustain growth.
Together with the biofuel boiler, the company will install a water storage tank of no less than 1,000 cubic meters, where the heat produced would be accumulated in water (when the heat needs are lower, e.g. during daytime) and which would be put to use when the need arises.
The company’s current 1.9 MW electricity generation capacity is already exhausted for the technological needs of other equipment. Therefore, together with the boiler, the company plans to install a 1.7 MW co-generation gas powered plant, which will produce enough energy to satisfy the increased demand for electricity. The co-generation plant will produce heat and electricity, which will be used for heating the greenhouses.
