Description
The main objective of the project is implementation of a 1 MWp floating photovoltaic system to assure electricity from renewable resources for the own consumption of TMK HYDROENERGY POWER SRL (TMK), and to reduce its CO2 emissions. The company conducted a feasibility study from which it resulted that the installation of a floating photovoltaic plant has obvious advantages'': high energy production efficiency, production of renewable energy and the reduction of energy costs. Floating photovoltaic panels perform between 5% to 15% better due to the cooling effect of water and due to water reflection, are less impacted by shading from other buildings and use inactive spaces such as the lake''s surface.
The technical solution proposes the development of a 1 MWp floating photovoltaic plant on Grebla Lake, which will be connected to the electricity grid. The solar power generated will partially meet the day-to-day energy needs of TMK operations. The electricity produced will be transformed into low voltage by inverters. The solar panels will be located at approximately 5 meters far from the banks. The entire portfolio of photovoltaic islands can be monitored centrally by the Central Unit (Grebla dispatcher). The photovoltaic plant will produce 1.087 MWh/year electricity for own consumption.
The project will be implemented by the following stages:
- Design and permitting consents – Technical design and obtaining consents for construction and operation from the local planning authority.
- Procurement – Carrying out tenders and securing the supply of the necessary products and services.
- Construction – Physically realizing the installation: Civil works, electrical install, FPV install.
- Commissioning.
- Environmental assessment.
The investment targeted by this project has a positive impact on the company. Its implementation reduces energy consumption from conventional sources, energy cost economy and gives a partial energy autonomy.
Summary of project results
In order to minimize the impact of the lack of precipitation due to climate change, the failures of the water transport system and the impact of the hydro system maintenance period, the Promoter analyzed the use of the existing hydro infrastructure to achieve an energy mix by diversifying the primary energy source (water). Before the project implementation, the Promoter conducted a feasibility study from which it resulted that the installation of a floating photovoltaic plant has obvious advantages: high energy production efficiency, production of renewable energy and the reduction of energy costs. Floating photovoltaic panels have these advantages: perform between 5% to 15% better due to the cooling effect of water and due to water reflection; are less impacted by shading from other buildings; use inactive spaces such as the lake''s surface.
The project consisted in implementation of a floating photovoltaic system placed on the lake, with a total installed capacity of 1 MWp, in order to produce electricity from renewable sources and to reduce CO2 emissions.
Outcomes:
a) Estimated annual CO2 emission reductions: 333 tonns of CO2 eq./year;
b) Energy produced from other renewable sources in MWh/year: 1.087 MWh/year;
Expected outputs:
a) Installed capacity for production of electricity (in MW): 1 MW;
b) Number of new installations for production of renewable energy: 1 installation;
Other indicators:
- Number of staff trained in the project: 2 employees.
The floating photovoltaic system contributes to decreasing the dependency on conventional sources by locally producing green electricity. The implementation of renewable energy allows the company to decrease annual CO2 emissions with estimated 333 tonnes of CO2 eq. per year.
