4 Changing Energy Landscape Today s energy landscape is evolving and Utilities are being confronted with an uncertain operating environment driven by climate change, regulatory policy, security, rapidly changing technology, and increasing customer expectations for reliable and quality power. 4 1 Climate Technology change is innovation requiring is action accelerating Clean energy legislation (renewables, Energy Efficiency) Increase in weather related outages To meet tomorrows energy challenges the future grid will need to be: 2 Technology Innovation innovation is accelerating Installation base of solar is growing Costs of solar/storage are declining Clean Lean 3 Customers are becoming Increasingly Digital Customer segments of one Pervasive Connectivity of digital devices Decentralized 4 Our always on way of life needs protection Cyber and physical security Resiliency Communal 4

5 Energy Infrastructure Modernization Act (EIMA) In October 2011, the Illinois General Assembly enacted the Energy Infrastructure Modernization Act (EIMA), setting in motion a $2.6 billion, ten-year investment by ComEd to strengthen and modernize the state s electric grid The Investment Plan had two primary components: 1. Reliability-Related Investments $1.3B over 5 years, cable replacement, manhole refurbishment program, storm hardening program, wood poles program, and building two training centers 2. Smart Grid-Related Investments $1.3B over 10 years, distribution automation, intelligent substations, smart meters, and cyber secure communication network Invest in Illinois $1.3B in system upgrades $1.3B in smart grid 2,000 full time jobs ISEIF Smart Grid Test Bed $50M for customer assistance Increased diverse supply chain Stabilize the Regulatory Environment Annual filing and reconciliation Legislative pre approval of partial investment ROE set by formula of 30Y T-bond bps ± 50 bps earned ROE collar Regulatory asset treatment 1 X items >$10M Customer Value Reliability improvement targets Customer service improvement targets Failure to meet targets = ROE penalties Legislation sunsets in 2019 Costs flow for bill credits/ increases Average rates increase < 2.5% 5

6 EIMA Impact Realized 6 As a result of EIMA, ComEd has continued provide sustainable reliability results for our customers as a result of a stronger, smarter, and more reliable electrical grid; while improving customer satisfaction. 34% reduction 42% reduction IEEE SAIFI w/ Storms from 1.16 to 0.76 All-in CAIDI from 199 minutes to 115 minutes 7% improvement 58% reduction 6 Customer Satisfaction Index from 7.46 to 7.97 Customer Satisfaction Index from 1416 to 595 (2015)

7 The Future Energy Jobs Act 7 The Future Energy Jobs Act (FEJA) is a comprehensive bill that provides a solution to present and future energy challenges. The FEJA will strengthen our economy and drive a clean, more secure energy future. The bill will: Substantially expand energy efficiency programs to drive customer savings and also expand options for commercial, industrial and low-income customers. Commit $750 million of funding for low-income programs. Protect 4,200 jobs and preserve $1.2 billion in economic activity annually. Position Illinois as a leader in zero-carbon electricity. Strengthen and expand the Renewable Portfolio Standard to ensure stable, predictable funding for renewable development, providing $180M per year growing to $220M per year- in funding for renewable resources. Provide job training and create thousands of clean energy jobs in energy efficiency, energy innovation and renewable power industries. Preserve competitive rates, given nuclear plant closures would add up to $1.85 each month to the average ComEd residential bill. 7

8 Modernizing the Grid 8 New grid advancement programs will focus on building resiliency and reliability into the physical system, maintaining and improving asset health of our already existing smart grid infrastructure, and building additional functionality and added value by leveraging our current asset base. 8

9 Utility as a Platform The traditional Utility business model needs to evolve to include new programs, and services. ComEd envisions future grid services to leverage the physical (the utility grid), communication (smart meter network), and social (collaboration and connection to the customer) networks that we use every day. 9 Data analytics services Home appliances Energy transactions Connected devices Community solar UTILITY PLATFORM Energy Efficiency DER offerings Financing Small business programs Home services 9

10 DOE Grants and Cutting Edge Applications Microgrid Controller The DOE awarded approximately $1.2 million to ComEd and it s partners to develop and test a commercial-grade microgrid controller capable of managing two or more clustered microgrids Bronzeville Community Microgrid Grid Connected Islanded SHINES- Sustainable and Holistic Integration of Solar and Energy Storage The DOE awarded $4 M to ComEd to utilize smart inverters for solar PV and battery storage systems Proposed SHINES project will deploy high power solar PV and a high-power Battery Energy Storage System (BESS). 10

11 Energy Storage Roadmap ComEd has developed a 10 year roadmap for integrating BESS applications within the transmission and distribution (T&D) system. Identify applications of interest - Applications within viable current regulatory framework Assess business benefits and penetration levels of energy storage for selected combined applications and use cases kw Capacity Upgrade Deferral Feeder Load at Substation and Battery State of Charge Load kw w/o BESS kw w/ BESS kvar w/o BESS kvar w/ BESS Time The BESS contributes to shed the load at the substation avoiding reaching the system peak. Circuit Voltage before/after smoothing Voltage (pu) Renewables Integration Vpu_B3_Before Vpu_B3_After The BES on the circuit are used to smooth Time PV production and absorb the volatility 11

12 Community Energy Storage (CES) 12 Pilot and test the use of small-scale BESS to reduce outage impact for customers who experience an above normal number of interruptions. 2 CES units CEMI-7 Customers - Customers that have experienced 7 or more outages in both of the previous two years Project Objectives Evaluate energy storage as an opportunity to mitigate reliability issues Deployment of CES units on the secondary side of the distribution transformer Demonstrate the concept of resilient community Project Benefits to be Studied Reliability (reduced outage frequency and reduced outage duration) Increase customer satisfaction Reduce number of customer targets 12

13 Representative Feeders Hosting Capacity ComEd is working to develop metrics and modelling techniques which can be used to provide high confidence screening of DER interconnection requests. 13 Current Techniques: Heuristic screening techniques, which are the most widely utilized at present, allow for expedited but often inaccurate assessments of these limitations Feeder Loading Data Feeder Models Constraint Values Feeder Simulation Hosting Capacity Whole-ofnetwork Analysis Kernel Density Estimation (KDE) Feeder Simulation Results System Hosting Capacity Hosting Capacity = Hosting Capacity PDF and CDF Detailed engineering studies, which is the technically ideal solution, provide an accurate estimate but are prohibitively time consuming to undertake Hosting Capacity To resolve this issue techniques are being developed that provide a more reasonable trade-off between accuracy and efficiency through data analytics and advanced modeling 13 Feeder Data # Clusters Clustering Analysis Feeder Classification Clustering Example Characteristic Feeders 13

14 Community of the Future 14 Community of the Future - A place where ComEd and a local community collaborate to create a smart community connected, custom, livable, and, sustainable A community where the energy system and the many uses of its digital network is localized and humancentered. Where residents and businesses have more options and control, can reduce their environmental footprint, and can benefit from new products and services. The Community of the Future promotes piloting customerfocused initiatives that: Create a smarter, more secure, more reliable, more resilient and affordable grid. Connect residents to smarter technology that enable them to make an impact on their energy usage, cost, and carbon footprint. Enhance livability, workability and sustainability. 14
