construction pit;
• a bridge was constructed downstream from the HPP;
• the spillways were concreted;
• the installation and concreting of guides for hydromechanical
spillway equipment commenced;
• the Agreement on By-Pass Financing was signed;
• the Protocol and Agreement on road deviation at
HPP Krško were concluded.
HPP Brežice and HPP Mokrice
At HPP Brežice and HPP Mokrice, the following important
events took place in 2008:
• the procedure and preparation of national spatial
development plans were carried out (NSP);
• expert bases were produced for the NSP;
• technical and spatial documentation was prepared.
Project investors are HSE, DEM, SENG, TEB and GEN
energija, financing the HPP construction on the lower
Sava River in proportion to their equity stakes in HESS
and in line with the investment payment plans. In September
2008, HSE drew a long-term loan from the EIB
in the amount of € 74 million for financing the investments
in HPP Blanca and HPP Krško.
PSP Avče
PSP Avče will be the first pumped storage hydro power
plant, contributing to the higher production of peak
electricity required by the Slovene energy system, and
the existing production capacity of SENG and HSE. In
addition to the above advantages, PSP Avče plays an
important role in the regional and urban development
of the area, and in ensuring higher employment rates in
the economic sector, promoting the economic development
of the area, and developing the Banjšice Plateau
through the promotion of tourism at Kanalski Vrh.
In periods of low electricity prices (at night and on
weekends), the PSP uses electricity to pump water
to the reservoir, whereas in periods of high electricity
prices (work-day peaks), the accumulated water
is used for electricity production. The investment in
this plant has been under way since 2003. The facility’s
construction started when the building permit
was obtained in September 2004. The developments
on site commenced in December 2004.
Technical data of PSP Avče:
maximum gross head:
Hb = 521.00 m
useful water volume: Vk = 2,170,000 m 3
rated flow (turbine regime): Qi = 40 m 3 /s
rated flow (pumping regime): Qč = 34 m 3 /s
rated turbine power:
Pi = 185 MW
rated pumping capacity:
Pč = 180 MW
annual electricity production: El = 426 GWh
annual energy consumption for pumping: Eč = 553 GWh
In 2008 the following important events took place at
PSP Avče:
• the upper reservoir and the intake facility were constructed,
work was carried out on the reflective and
protective barrier next to the reservoir, and work involving
landscaping of areas, biotope and info point
facility construction commenced;
