SKAVICA HPP DEVELOPMENT (REPUBLIC OF ALBANIA)
KESH sh.a., the Albanian National Power Corporation, in its intention to increase its generation capacities through utilizing renewable resources available, is resuming work on the project for Skavica HPP Development on the Drin River Cascade. Conceptualization of the project began in the 1990’s and is being continued through close cooperation between our corporation, international institutions and international experts, with the aim of utilizing the full energy potential of the Drin and Zi river. Funded by the WBIF, a grant of 1,5 million euro was approved to support the preparation of a feasibility study for the projects. A team of International and National experts has started to work on January 2019 and the final report is due in Autumn 2020. The first phase consists of drafting a pre-feasibility study in which the consultant group will analyse three different alternatives with one or two dams solution as well different heights and different installed capacities (up to 200 MW) alternatives. A decision on the best option to be followed is expected by September – October 2019, the consultant will also propose different alternatives for financing the construction of the HPP.

MODERNIZATION OF VIDRARU HPP (ROMANIA)
May 2019 Romania’s state-owned hydropower producer Hidroelectrica, has launched an international tender for the modernization of the 220 MW Vidraru hydropower plant and dam on the river Argeș in the southern central county of Argeș, which is located in the region of Muntenia. Bids are due by June for a turnkey contract for the design, supply, installation, testing and commissioning of mechanical, hydro-mechanical, and electrical equipment for the plant, dam and pressure node as well as integration of already modernized installations (220-kV substation, SCADA and 125 kVA generator group at the Vidraru dam) as well as dismantling of the existing equipment and personnel training. The project aims to extend the HPP’s life by at least 30 years and to increase the active power of each hydro-aggregate from 55 MW to 58.8 MW at least, while ensuring better reliability, lowering the maintenance needs and increasing safety in operation.
