Bulgaria utility Natsionalna Elektricheska Kompania EAD (NEK) seeks bids for design, document preparation and construction supervision of Yadenitsa Dam on Bulgaria’s Yadenitsa River. Bids are due September 25.
Construction of Yadenitsa (or Jadenitsa) Dam would expand the lower reservoir of the 864-MW Chaira pumped-storage project, allowing it to generate for 22 continuous hours rather than the current 6.4 hours.
NEK last year recruited consultants for a program to rehabilitate:
- the Belmeken-Sestrimo-Chaira hydro complex featuring Chaira, the 375-MW Belmeken Pumped-Storage project, and the 240-MW Sestrimo and 120-MW Momina Klisura hydro projects; and
- the 14-MW Vacha 1 hydro project 110-kilovolt switchyard and other hydro power project systems of integrated control. The Vacha 1 and 7-MW Vacha 2 plants are located at 80-MW Krichim Dam.
Firms interested in the Belmeken-Sestrimo-Chaira and Vacha 1 work may obtain additional information about those projects by contacting Redy Stoyanov, Project Management Department, Natsionalna Elektricheska Kompania EAD, 5 Vesletz Str., 1040 Sofia, Bulgaria; Fax: (359) 29881374; E-mail: email@example.com.
NEK now seeks bids for implementation of research and design works for updating the detailed design, and preparation of technical documents for award of construction works for the project to increase the volume of the lower reservoir of the Chaira project by construction of Yadenitsa Dam and a reversible pressure tunnel connection with Chaira Dam. Work also would include supervision during construction and preparation for project operation.
The work would require 86 months at an estimated cost of 3.5 million lev (US$2 million).
