Bundling the energy forms

2. Bundling the energy forms Building a city on waste heat – a technological perspective Marko Riipinen HELEN, Finland 20.6.2019

3. Interactive energy community In modern city energy infrastructure connects buildings to each other. • Energy flows are managed • Heating-, Cooling-, and Electricity demands are balanced and optimised by energy operator • Customer value creation is key driver for Service provider

5. Citiesarefull of energy Available energies can be recycled, stored and reused efficiently and most optimal way • Waste heats from properties such as shopping centres, data centres, offices and residential buildings is recovered with district cooling. • In thefuture, utilisation of variousheatsourceswillincrease, includingwasteheatfrompurifiedwastewater, solarheat and wasteheatrecoveredfromproperties and data centres. • Lowtemperaturethermalenergyflowscanbecirculated at thebackground of the city

6. Smart City of Helsinki

7. Bundling the energy forms It’snotanymore just questionaboutheating, cooling and electricity. • The significantincrease of solar and windpower in electricity market callsvariousflexibilities for production and use of energy. • Weatherproof production, such as combinedheat and powergeneration, hydropower and nuclearpower, is needed for the coldestperiods of the year. • Demand response and energy storagesystemswillincrease and comemorecommon.

9. The role of customerswillincrease • A climate-neutralfuturewillbeachievedthroughinnovative, customer-focusedsolutions and services. • Residents willalsobecomeactive energy producerswhensolar and electricitystoragesolutions and varioushybridheatingsystemsbecomemorecommon. • Energy companiesbusinessesarebased on • Value creation • Sustainability • High efficiency • Energy recovery • Energy as a service
