2 Work Package 4 - Analysis of the cities energy systems and networks Energy Consumption in Municipal Services and Estimation of solar potential in the cities THE INSMART FINAL CONFERENCE - 15 MARCH 2017 Brussels, Belgium 2

3 Outline WP4 Main Objectives Approach Main achievements and challenges Urban Spaces Water and Sewage systems Municipal solid waste chain Tertiary sector Buildings managed by the municipality Other tertiary buildings Energy supply systems RES potential assessment Lessons Learned Focus on PV potential THE INSMART FINAL CONFERENCE - 15 MARCH 2017 Brussels, Belgium

4 WP4 Main Objectives Analyzes of the current status and future plans Identify applicable technical solutions Inform the GIS platform database and energy system model of each city Urban spaces Water and sewage system Municipal Solid Waste chain City Energy supply system Buildings under Municipal Management Additional! Private services Buildings Additional!

5 Methods and tools Approach Data Acquisition: Municipality teams + technical teams contacted local stakeholders for data collection (also created the opportunity to introduce/open the project to local community).

6 Urban Spaces - Gardens/green areas and public fountains Characterization of the public urban spaces with relative importance consumption of energy within the city Gardens/green areas location in Évora municipality GIS Map of Parks and Gardens in Nottingham Electricity consumption of gardens and fountains in 2013 in Évora municipality (kwh) Type/electricity consumption Peak (kwh) Off-peak (kwh) Total Gardens Lighting Irrigation Other Fountains

7 Urban Spaces - Public lighting Nottingham GIS Map of Street Lighting Points Nottingham information on public lighting characterization Sum Lamp Circuit Wattage (W) Energy consumption (kwh) City Districts Arboretum Aspley Basford Berridge Bestwood Bilborough Bridge Bulwell Bulwell Forest Clifton North Clifton South Dales Dunkirk & Lenton Trikala public lighting: Energy consumption per City Sector (MWh/yr)

8 Water Supply, Sewage and MSW System Évora water system facilities Trikala Sewage systems (MWh/yr) Plant Name of the Plant Energy consumption 2014 kwh Production year 2014 kwh Plant operating hours per day Quantity of treated sewage Depurator DEP CESENA Depurator DEP PIEVESESTINA Depurator DEP CALABRINA Depurator FITO CALABRINA Depurator FITO BAGNILE

9 Services Sector Buildings managed by the Municipality Location of Évora schools Electricity consumption of the buildings and equipment s managed by Évora municipality in 2013 Sector Peak Off-peak Total annual (MWh) (MWh) (MWh) Municipal buildings Education Dwellings for social housing Churches and monuments (lighting) Sport facilities (e.g. swimming pools, sports halls) Leisure (e.g. Teatro Garcia de Resende)

10 Services Sector Private Buildings Retail: Large Food supermarkets and local shops (those within the residential areas); Office buildings Education: Primary, secondary and college/ University; Location of small services buildings in Évora municipality Leisure: Restaurants, hotels and cinemas Health: Hospitals and health centers Energy consumption in 2013 (GJ) Fuel Offices Retail Leisure Education Health Electricity Natural Gas LPG Gasoline Diesel Total

11 Energy supply system Cesena natural gas network Assessment of RES resource potential 1) Solar technologies (PV and solar water heaters) 2) Geothermal (low enthalpy geothermal). 4) Wind resources in the city. 5) Biogas from the sewage treatment system and the landfill. 6) Biomass in areas surrounding the city. Geothermal potential in Greece

12 Estimation of solar potential in the cities Solar thermal Solar technologies Solar photovoltaic Diverse PV technologies Monocrystalline silicon Multicrystalline silicon HIT (Heterojunction with Intrinsic Thin Layer) Amorphous silicon (nontransparency type) Rooftop Façade Plant size Residential Services Residential Residential Due to the growing importance of solar technologies as decentralized energy supply technologies a supplementary assessment was made in order to identify each city technical potential.

13 Solar PV potential in the cities Solar technologies technical assessment based on state of the art literature. Estimation obtained from an optimal combination of a robust and detailed approach with the available information.

14 Estimation of solar PV potential in the cities PV utility scale Location of PV-track systems for different land scenarios (1 MW project size)

15 Estimation of solar PV potential in the cities Technical potential for all the cities Per Building typologies (Évora) 314 MW Per city zone (Nothingham)

16 Estimation of solar potential in the cities PV potential (kw) Cesena Trikala Évora

17 Lessons learnt Different sectors were characterized to feed the city GIS platform and the energy system tool, assuring the city energy system integration; Challenges on the harmonization of data at different scales (e.g. point data on public lighting to areal information); All cities faced some difficulties on data privacy issues from the companies and on response time; The solar technologies potential assessment methodology can be replicated to other cities; The WP4 allowed a important interaction and engagement with key city stakeholders, and the opportunity for dissemination of the project;
