Energy requirements What are the drivers for energy in Smart Cities? - Attracting talent and investment - Economic growth - Improving services for the customer - Reducing the cost of delivering services - Leveraging infrastructure: - Street lighting - Communications - Health services - Etc.
  • 9. © 2014: Smarter Grid Solutions Ltd. (SC344695). All rights reserved. Energy requirements Requirement is to have reliable and cost effective power supplies…. Some questions: How much electricity does a city need now and in the future? Will the electricity demand be more ‘peaky’? Where will the electricity come from? How does it get from where it is generated to where it is consumed? Can the local and national grid cope? Is this where Smart Grid meets Smart City?

The new paradigm CENTRALISED GENERATION TRANSMISSION NETWORK DISTRIBUTION NETWORK DISTRIBUTION NETWORK DISTRIBUTION NETWORK DEMAND DEMAND DEMAND DEMAND One-way power flows Remote generation Little communications Passive network Delivering electricity passively to consumers The traditional paradigm: “Generate what is consumed”

The new paradigm CENTRALISED GENERATION TRANSMISSION NETWORK DISTRIBUTION NETWORK DISTRIBUTION NETWORK DISTRIBUTION NETWORK DEMAND DEMAND DEMAND DEMAND Offshore and onshore windNew marine and hydro Aging assets DG Small and large solar Electric Vehicles Heat pumps and aircon Micro-grids Clustering New loads to connect Network loading and voltage limits Two way power flows Less predictable load and generation Consuming what is generated

Smart Grid for a Smart City • Increasing generation from renewable intermittent sources – Improved forecasting of resources and scheduling of consumption – Time of use tariffs – Increasing use of demand response and balancing services • Increasing demand on the network (e.g. electric vehicles) – Smart charging for local and national constraints • Increased resilience – More distributed and back-up generation – Emergence of microgrids – Supply of critical loads What does this mean for traditional utility companies and their business model? What opportunities does it create?
  • 14. © 2014: Smarter Grid Solutions Ltd. (SC344695). All rights reserved. Case studies • Smart EV Charging • Sharing demand response resources for local and national needs • Proving responsiveness to Time of Use tariffs • Integrating DG to the local grid Proving the Smart Grid for a Smart City • Growing a financially rewarding demand response programme • Microgrid development • Integrating Distributed Energy Resources and Microgrids • Integrating EVs and options for Smart EV charging The passive one-way electricity grid of today is going to have to change for cities to realise their ambitions BUT this will be highly disruptive to traditional utility business models
