Hydropower: The backbone of Austria’s power systemAustria can rely on efficient hydropower plants. Our

run-of-river power plants generate CO2-free electri-

city around the clock and thereby ensure a reliable

supply of electricity for the local population and

industry.

In addition, storage and pumped storage power

plants can take large quantities of electricity out

of the grid from generation surpluses, increasingly

from volatile renewable energy, store it temporarily

and then feed it back into the grid at short notice as

required. The storage and pumped storage power

plants are just as valuable for providing balancing

energy and system services to maintain the system

and grid security, which is becoming more and more

important as the quantities of volatile, renewable

energy sources increase.

Introduction

Electricity generation from hydropower comes with

a number of ecological but also economic benefits

and is absolutely necessary for achieving climate

protection objectives. However, it also means an

intervention in the water regime and hence the

“water body habitat”. To minimise the impact of this

as much as possible, Austrian hydropower operators

have endeavoured for years to reduce these effects

both in the planning and the construction and ope-

ration of the facilities. The water management and

water ecology objectives as well as the recommen-

ded actions are clearly defined in the Water Frame-

work Directive (WFD) and its implementation via

the water management plans (including all accom-

panying documents). Observing the right balance,

effectiveness and cost-efficiency of the measures is

an important concern of the industry.

What does the WFD meanfor Austrian hydropowerThe Water Framework Directive of the EU, which

has been in force since December 2000, poses major

challenges to Austrian hydropower companies.

The long-term objective of the WFD is to gradually

achieve a good ecological status or at least potential

(for heavily modified water bodies) for all bodies of

surface water and ground water. Based on the eva-

luation of the water body condition, measures are

stipulated in the National Water Management Plan

(NGP) that are required in NGP I for the time period

from 2009 to 2015 in the priority water bodies

(catchment areas greater than 100 km2). In addition,

five federal states have enacted corresponding state

ordinances on the basis of these NGP obligations.

These rules result in comprehensive requirements

for all stakeholders, including hydropower opera-

tors, for specific measures to improve the status

or potential.

INTRODUCTION

Fish pass at the Gössendorf power plantIn the implementation period of NGP I from 2009 to

2015, an investment of around 190 million euros was

made by the affected member companies of Oester-

reichs Energie for the implementation of the WFD’s

133 measures.

Approximately 20% of this was publically funded. In

addition to these investment costs, the companies

also bear the ongoing maintenance and operating

costs as well as monitoring expenses with a massive

additional financial burden. For many of the projects

still in progress, a final tally of the investments and

monitoring expenses, the funding and also the pos-

sible generation losses are still not possible. Hence,

the total burden for hydropower will still increase.

In addition to the high financial outlay, the measu-

res for creating ecological connectivity for fish, for

increasing the amounts of residual water and for

improving the ecological habitats, also cause a re-

duction of the local renewable and CO2-free electrici-

ty generation on a scale of around 160 GWh per year.

That corresponds to the average consumption of

around 45,000 households. If this energy consump-

tion were to be covered by thermal power plants,

it would mean more than 140,000 tons annually of

additional CO2 emissions in Austria (based on the

ENTSO-E fuel mix).

INTRODUCTION

To realise these 133 measures, numerous sustainable

projects have been implemented and will continue

to be implemented in almost all federal states, on all

major watercourses:

▪ Ill: 5 projects

▪ Inn: 7 projects

▪ Drau: 19 projects

▪ Mur: 36 projects

▪ Salzach: 19 projects

▪ Traun: 12 projects

▪ Enns: 8 projects

▪ Danube: 27 projects

These projects include, for example, measures re-

garding the creation of ecological connectivity (68%

of the measures), increasing the residual water flow

(13%) and improving the natural habitat/morpho-

logy (19%). Each individual project is planned in a

location-specific way in close cooperation

between the operator, the responsible authorities

and affected stakeholders, whereby technical, finan-

cial, legal and ecological requirements are optimally

coordinated. After construction, the financially and

technically demanding projects will additionally be

subjected to monitoring often lasting several years

to ensure the operability and effectiveness of the

measure, and they must be monitored and maintai-

ned in ongoing operation.

Electricity price decline hampers NGP implementationThe implementation of these projects is being

hampered considerably by the market environment,

which has been challenging for years now with low

electricity prices. The past few months have brought

another massive intensification, and there is no

indication of recovery in the medium term.

INTRODUCTION

revenue potential for today has been cut in half.

Hydropower companies have reached the limits of

their economic resilience, and all requirements that

cause additional costs without additional revenue

mean further deterioration of competiveness.

From this perspective, it remains to be said that

hydropower, as a renewable electricity generation

technology that is CO2-free in operation, must retain

its key function in Austrian energy and climate

policies, and therefore an eye must be kept on the

economic existence of hydro companies. Only then

can the high economic value of hydropower for

Austria be preserved.

Therefore, greater attention will have to be paid to

efficiency requirements for projects in the future.

There is no doubt that Austrian hydropower will

continue to be committed to the objectives of the

Water Framework Directive. It is making its valu-

able contribution to achieving the objectives, not

only in ongoing projects but also in interdisciplina-

ry research for meaningful development of future

measures.

We are delighted to make this informative “perfor-

mance show” of the NGP measures of Austrian hyd-

ropower plant operators available to you, and wish

you interesting reading.
