4. ROLE AND ADVANTAGES
Key project considering the growing portfolio of electricity generation from renewable
sources, requiring the installation of additional balancing capacity. These shall be turned
to account not only on the ancillary services market but also on the load variations
balancing or power consumption market
Power plant of strategic role, the first great dispatchable consumer qualified to participate
at the NPS black-start in case of black-out
Operational flexibility and capacity to give a fast response to load changes, following to
provide power services in Romania and neighboring countries
Enhancement of the operational conditions related to the large units from nuclear power
plants, fossil-fueled condensation thermal power plants and cogeneration power plants,
by electricity transfer from idle to peak (during night and week-end), reducing the
consumption of fossil fuels, that are mostly imported
Benefits for all the segments of the competitive market, through a positive impact on
liquidity and price set on such markets
2014 Hidro Tarnița S.A. all rights reserved
5. FUNCTIONS PROVIDED
Electricity storage for a period of time
Supply of ancillary services for Romania and neighboring countries (frequency – power
regulation, fast tertiary regulation, reactive power and operation in compensation mode)
in order to meet the power quality standards
NPS balancing, considering the major increase in the portfolio of renewable sources
generation capacities (wind, solar etc.) which cannot be controlled, depending on the
primary sources specific to each category
Power supply in west of Romania, area characterized by a scarce production
Increase of the safety conditions in NPS operation and its exploitation under better
technical and economic conditions
Sustainable alternative of the Romanian hydroelectric potential development considering
the limited resources of raw material, in order to achieve cheap and non polluting
energies

Technical analysis highlighted the fact that the routes of OEL 400 kV, connecting Tarnita Lapustesti PSP and
Transelectrica (system operator), are actually included within a single corridor, outgoing from Tarnita 400 kV
substation, made of 2 rows of double circuits poles.
One corridor is dedicated to Tarnita-Gadalin route, of 74 km length, the second corridor being dedicated to
Tarnița – Mintia route, of 158 km length.
This solution provides, for each lot of 500 MVA, the discharge/supply of the power plant both towards Gadalin
station and towards Mintia station, providing the adequate reliable operation of the power plant, as well.
Elements of NPS connection are:
- 400 kV substation
- PSP double circuit OEL 400 kV – Mintia (158 km);
- PSP double circuit OEL 400 kV– Cluj Gădălin (74 km).
