The Psychology of Transition
„I want to be independent of big energy companies and I want to decide wether I produce by myself, or when, how and from whom I buy energy. „ „I want to be a creative part of the new energy system and I want to understand it.“

202020 Strategy and Beyond
save climate
guarantee a save and low cost electricity supply
ensure economical growth and create new green markets
2020 Strategy is the ignition for large scale RES integration being continued by the 2030 greenbook and the 2050 Roadmap: reduce emissions by at least 20 % until 2020,
20 % more efficiency by 2020, 50 % more efficiency by 2050,
20 %tot RES share by 2020 = > 32 % el, 80 %el in some countries by 2050,
enforce sustainable ressource management,
reduce external energy dependency significantly.

More than 30 %el RES-prod.-share long for additional flexibility steps.
Existing thermal plants are optimised
for huge full load hours and full load
operation while turndown reduces
energy efficiency and drives costs.
Retrofit measures will increase
operational flexibility only to a certain
extent.
New thermal and RES plants will have
more flexibility by improved technologies.
Gas power plants are expected to be the
thermal backbone until 2050 and beyond.
Thermal production capacity to be reduced.
Must run capacity 10 – 20 GW.
Thermal flexibility to be improved.
Must Run > 10 GW of thermal units

Austria and Germany consequently follow their NREAP-path
and even exceed it. Up to now national goals are met.
Restrictions of thermal plants, wind and photovoltaics more
and more long for flexibility measures to stabilise the system.
Production efficiency is being reduced significantly.
Large scale storages will be missing.

Alpine HPS capacity to complete German daily HPS facilities.
Reservoir – volumes and drop hights limit German
hydro power storage facilities for short-term
operation to maximum of 1 day. All relevant strategy studies expect from 2025 on
a significant increase of medium and seasonal
storage when baseload capacity reduced stepwise
and renewables’ share will become dominant. The challenges until 2025 can be met mainly by
increased power installation (turbines and pumps)
while post 2025 power and energy storage is
needed urgently. New Alpine HPS reservoirs will meet these
challenges by progressive power and capacity
development.
The German HPS-system has
short- term storage characteristics.

Simultaneous short-, medium- and long-term storage with alpine HPS.
Flexible turbine and pump capacities
combined with
huge reservoir capacities/drop heights
together with
a maximum of availability
give a broadband operation-service
for the entire system and thus guarantee system
stability and security of supply.
Highly flexible load alternations at huge gradients
meet all LFC requests simultaneously with
Charging or discharging the system for short-,
medium or long term shaping and seasonal
energy storage.
Ancillary services, residual load management
and seasonal storage is the core business for
HPS in the 21rst century.

Residual load dynamics longs for additional flexible prod. capacities.
Nuclear turn off and reduction of baseload
capacities will double demand for flexible feed in
capacities and multiply demand for flexible feed out
capacities by factor 5. PV gradients expected > 5 GW/h. Offshore wind, compensation effects of
geographically dispersed onshore wind and flexible
RES-production may stabilise neg. LFC
(Pumps, ...) demand at approx. – 20 GW. Hours with negative residual load are expected
to rise from nearly 0 today to 500 in 2030
and up to 2.500 in 2050. It will need all mature technologies in an optimised
way to meet these challenges.
80 % RES integration until 2050.
Significant reduction of baseload capacities.

Alpine and scandinavian hydropower will meet the challenge together.
D-A-CH together with scandinavian storage
and HPS facilities will significantly help to
meet the future challanges by creating
win-win opportunities within the
authorized potential: large scale RES integration
thermal production optimisation
system stability
price stabilisation
CO2 reduction
Alpine HPS benefit from strong
interconnectors to the German system.
Austria’s hydraulic potential is only used
by 50 %.
Appr. 13.000 GWh are expected to be
developed. Tirol shares 21 %.

System flexibility issues for the 21rst century
1. sufficient power reserves by production optimisation, weather – oriented DSM,
2. guaranteed power availability for defined time frames,
3. effective and efficient RES and thermal surplus recovery,
4. fast power control to meet huge residual load gradients mainly caused by PV,
5. sufficient and highly efficient storage facilities.
1. market oriented system services
2. power and energy oriented market design
