The Danish Point of Departure
1973-74 oil crisis
2 countries 99% dependent on imported
energy
• Japan
• Denmark (oil and coal)
Supply situation exacerbated by inefficient
energy use
Pollution caused by fossil fuels
Today – Some 30 Years Later
Main Results - Denmark:
Net exporter of oil and gas
Lowest energy consumption per unit of
GDP in EU
Highest contribution to electricity from
new renewables in EU (world)
Most efficient clean coal technology world
wide

High economic growth: GDP +56 % since 1980
Primary energy consumption constant: 2 % higher in 2004 than in 1980
CO2 reduced substantially: 35 % lower in 2004 compared to 1980
Three Main Reasons for De-coupling
Economic Growth and Energy Consumption
District Heating and CHP
Energy Savings
Renewable Energy
Particular emphasis on wind
power in this presentation

RE share of Gross Energy Consumption (%)
RE share of Electricity Supply (%)
Wind Power – a good business
Installed capacity = 3,118 MW (2004).
420 MW is off-shore (529 MW globally)
Wind power supplies almost 20% of the
gross electricity consumption (2005)
The Danish wind turbine industry
employs 20.000 persons and sells
turbines for 4 Billion US$ (2005)
Most of the turbines are exported and
Danish wind turbine industry serves 1/3
of the world market (2005)
16 Years of Offshore Wind Experience
• First Danish offshore wind
farm 1991
• Strategic mapping 1995
• Capacity now 423 MW.
• 2 x 200 MW wind farms to
be established in 2009
and 2010
• Existing and approved offshore capacity (825 MW)
= 8% of total electricity
consumption in 2010
• Potentials = 50% of
electricity consumption
Challenge: To Feed the Grid with Wind Power
(Western Denmark as an example)
Grid Management of
Fluctuating Wind Power
Large regional grids (only 2 transmission grids
in DK) provide access to back-up capacity.
Nord Pool: Level playing field ensures costeffective back-up capacity from Nordic region
Short gate closure times to allow trades close
to real time
RE electricity is guaranteed transmission and
distribution
Further integration of wind power is possible
Storage as a future option
High Public Acceptance of Wind Power
Wide spread grass root support (except close
neighbours!)
Bi-partisan political support and leadership
Incentives for small-scale local investments in the
first years.
Careful involvement of the public in decision
procedures. Compulsory public hearing.
BUT: Problem of the past = Oversubsidiation

A wind mill on a good site is competitive with a gas-fired power plant by 2010.
Feed-in tariffs must be adjusted accordingly or replaced by market tariffs.
Need to Diversify Support Mechanisms
Danish experience shows advantages with an
evolution in support mechanisms
o Investment grants
o Fixed feed in tariff
o Market based tender (variable premium)
Feed in tariffs have their advantages
Market based systems to be considered on the
long time frame
KWh-subsidies gradually replaced by support to
R&D for new wind mills
Still support of 1.3 Eurocent/kWh for new mills
Confidence-Building Measures for
Investors in Offshore Parks
Screening to mature site suitability
Fixed price in 50,000 full load hours (last tender:
almost 7 Eurocent per kWh as fixed price for 12
years without compensation for inflation)
TSO to finance, construct and operate
transformer station and sea cable
Security: Grid connection is available in due time
Financial compensation if the power produced is
curtailed = Estimated loss from unrealised sale
Contractual agreements – adjustment in tender
conditions
One stop shop communication
Lessons learned on RE-deployment
Long-term strategy and commitment needed on development
and research programmes.
Develop technical standards. Technology drivers are an
important incentive.
Gradually prioritize the deployment efforts - different
strategies for different stages of technology development.
Mature stage => more market oriented focus
Transparent and confident-building measures for investors
Government coordination to facilitate smooth administrative
procedures, credit facilities, appropriate subsidy schemes
Lessons learned from Wind Power:
Prices are constantly falling (don’t over-subsidize).
Integration of a large capacity of wind is possible.
But some support is still needed
Total support for wind in DK (19%) increases the total enduser price by ¾ Eurocent per kWh (excl. tax)
New Danish Energy Strategy in 2007
19 January 2007: The Danish government presented a new long
term energy strategy entitled “A Visionary Danish Energy Policy”
Long term vision: Denmark should in the long term become
entirely independent of fossil fuels
Targets for 2025:
o Reduce the use of fossil fuels by at least 15%.
o The share of renewable energy must be at least doubled to
minimum 30% of total gross energy consumption by 2025.
This implies that more than half of the electricity consumed
will be supplied by renewable energy and 10% share of 2.
generation biofuels in transport by 2020.
o Energy saving efforts will be increased by 1.25% annually with
a view to holding overall energy consumption static until 2025.
