• Danish district heating history

• News

Technically DH is NOT Complicated

4

DH is fuel agnostic!

Storage

Pipes, pumps, valves . . .

Heat demand

• Like your own boiler – a lot bigger and a lot smarter!!

• Moving “free” heat to a useful place

• Extremely well proven technology/system/idea/business!!

A few remarks

• Started small and only semi-planned • Danish DH is a complex structure • Developed over 100+ years • ESCO = “The DH Company” - council owned, not-for-

profit • No secrets – full transparency - stakeholders • A utility – like e.g. water, sewage, road • Building improvement from day 1!

DH in Denmark

• 63% of all house holds (1.632.000)- 98% in Copenhagen

• + 20.000 (2014)

• Today ~450 schemes (mergers will make this number smaller)

6

Denmark’s Wake Up Call – 1973

• 99% oil and coal = import dependence

• Inefficient energy use

Sustainable solutions needed!!

7

Consistent Energy Policy Long Term planning

Legislation – 1976 – Electricity Act (CHP, Cost Eff)

– 1979 – Heat Supply Act + RES + WtE

– 1986 – Decentralized CHP

– 1990, 1993, 2008 – Increased biomass (new CHP and conversion)

Incentives – 1981 – Investment grants for biomass DH/CHP – 1984, 1992 – Subsidies for CHP – 1994 – Financial support to establish DH on biomass or natural gas – 1991 – High energy tax and CO2 tax on fossil fuels

Clear business model – Lowest possible cost for end-users –Municipal guaranteed loans – Support from all levels of society – Strong cooperation across all borders

Plan – Coordinate – Legislate - Support

Make system “connectable” Avoch – Fortrose - Rosemarkie

B

• Planned system

• DHCs can work together

• More flexibility

• Expansions possible

• No cooperation between

DHCs

• Less flexibility

• No expansion

• Higher prices?

The more end users the better

The greater Copenhagen DH system – real time

20 municipalities

4 integrated systems

500,000 end – users

34,500 TJ (9,600 GWh,

32,700 GBtu)

The Future

–A central part of Smart Energy Systems & 2050 targets

– Integrate surplus wind and solar electricity

–Solar is blooming these years

DH Costs less than Natural Gas

13

~75% of schemes cost less than natural gas

~95% of end user spend less compared to natural gas

Heat Prices incl VAT 2013

385 schemes (18,1 MWh – 130m2 standard house)
