1 Engineering Sustainable Energy Systems The Green Islands case study Carlos A. Santos Silva MIT-Portugal Program / Sustainable Energy Systems Instituto Superior Técnico

2 São Miguel, Azores Lagoa Sete Cidades, São Miguel São Miguel Area759 km 2 (32%) Population (60%)

3 The energy system in São Miguel (… as perceived by the Azores local agents) Annual growth rate %4% São Miguel

4 Energy Strategy for 2018 Goals for all Azores –75% of renewables on electricity production –40% of renewables on primary energy ( electrification of other sectors ) Plan (for São Miguel) –3MW Geothermal by 2010 –9MW Wind by 2011 –10MW Geothermal by 2013 Questions –Another 10 MW Geothermal after 2013? –Storage system? –How to use biomass? –Is this enough? What else?

5 The energy system in São Miguel (… the real system in 2007) 47% 27%

6 Strategy for 2018 MIT Portugal Local Agents

7 Green Islands Project

8 Engineering a Sustainable Energy System –Technical dimension Storage / Smart Grids/ Electric Vehicles / Biomass –Economic dimension EU or PPP / Energy markets –Social dimension Acceptance / Behavior Changes / Education / Collective welfare –Critical Infrastructures Energy /Transportation /Communication –Energy and Sustainability Safety /Security –Fundamentals Complexity, Uncertainty…

9 Tools for Energy Planning Social Economic Environment (Technological)

10 Planning tools gaps HourYear Region /Country House /Neighborhood Second Space Time Projections Optimization Methodology

11 New generation of planning tools HourYear Region /Country House /Neighborhood Second Space Time Projections Optimization Methodology

12 Model Calibration (2008)

13 Green Islands Case: TIMES-MARKAL to build scoping scenarios Business As Usual –37 MW Geothermal: [ ] (2013) –5 MW Hydro –9 MW Wind (2011) MPPRen (+ Renewables & Storage) –47 MW Geothermal: [ ] +10 (2013) –9 MW Hydro [5+4] –9 MW Wind (2011) –10 MW Biomass (2013) –15 MW Pump-Storage (2013) MPPRenDom (+ Household Efficiency) –Energy Efficiency Gains from New Appliances –Electricity Demand Growth 2% MPPRenAll (+ Lower demand growth) –Non-Electric/Non-Transportation Demand Growth 1% MPPRenAllEV (+ Introduction of Electric Vehicles) –6% of Electric Vehicles in 2013, 30% in 2020

14 GWh Electricity Production Scenarios

15 Electricity Scenario for 2018 Two critical ideas – Reduce energy demand (e.g. energy efficiency in buildings) – Introduce storage systems (e.g. pump-storage or EV) Storage Energy Demand

16 Primary Energy One critical idea: – Change transportation system (e.g. EV)

17 Conclusions Engineering a Sustainable Energy System requires –Research: Extend modeling and planning tools to include all dynamics –Implementation: Energy efficiency (e.g. reduce energy demand in buildings) Change transportation paradigm (e.g. electrical vehicles)
