A tender for the installation of PV panels on the roof of the city hospital.
Bratsigovo municipality has a strong policy related to the energy efficiency and the use of renewable energy sources that leads to energy independence. Following this policy the municipal council decided to launch a procurement procedure for the installation of PV panels on the roof of the city hospital. The aim of the project is to secure independent energy supply for the needs of the hospital as well as to “switch off” from the conventional electricity supply network and to turn to RES.
Bratsigovo is quite a small municipality with a population of no more than 10 000 inhabitants. It is located high in the mountains which makes it a bit isolated, especially in the winter months. By sharing the experience of Bratsigovo municipality we wanted to convey the message that “when there is a will, there is a way”! Even though it is a small municipality, it manages to procure green and to successfully contribute to the energy efficiency policy in the region by reducing CO2 emissions. Electricity from RES is a good example of green contract
The hospital has pitched roofs suitable for the installation of a PV system. The design foresees the installation of 112 PV modules with a peak power 28 kWp and maximum power to the grid of 25 kW.
The calculated annual production of electricity amounts to 33,600 kWh/year.
• 41,795 EUR
Evidence of success
The expected production of electricity is 33, 60 MWh/year.
• resulted annual CO2 savings – 27.52 t CO2/a
• resulted annual costs benefits – 3,008 EUR/a
• pay-back period 10 years
Potential for learning or transfer
Award criteria used:
• Award criteria for longer term of payment – 15 points;
• Award criteria for shorter term of completion of the works – 25 points;
• Award criteria for lowest price – 60 points.
The contract had to be awarded according to the MEAT criterion. The tender is considered and marked as ‘green’, because it will lead to a substitution of conventional energy (electricity) used in the building by energy generated from renewable sources. This substitution will lead to significant energy and CO2 emissions savings.
Despite being a small public procurement tender, it deserves its place as an example set to other similar authorities and administrative staff. It may be easily multiplied on other public buildings, on kindergartens, schools etc. Turning to energy efficiency and RES is a good example of GPP promotion and driving green purchasing ahead. Authorities who implement GPP will be better equipped to meet evolving environmental challenges.
