The project also aims to strengthen links with the European electricity system, which is a priority for Moldova as it will help cement its association with the Energy Community Treaty. These links will facilitate the integration of Moldova's transmission grid into the European Network of Transmission System Operators for Electricity (ENTSO-E). The project includes the design and rehabilitation of a number of substations and transmission lines. This rehabilitation is expected to lead to improved security in the transmission network and energy efficiency. The replacement of the existing fleet of transformers is expected to lead to an efficiency gain of about 30%, reducing CO2 emissions by about 1 5,000 to 20,000 tonnes of C02 per year. Currently the consultant for the Project Implementation Unit and supervision support is being contracted and the procurement of the project will start in the second half of 2013.
