Resilient solar+storage+EVcharging microgrids May 2016 [email protected] 224-307-9663 [email protected] 239-287-6960 & [email protected] 401-369-0306 Solar+Storage+EVcharging paid by ISO & utility programs: Flexible Generation Interconnections, New Infrastructures Reinforcing the current centralized model High CAPEX intensity Demand Response Active Customer, Prosumers Energy Storage Creating a new decentralized model Lower CAPEX intensity Energy storage looks as the best alternative: Non invasive, Less expensive, scalable

How can a solar+storage+EVcharging microgrid pay for itself? Self-funded solar+storage+EVcharging by ISO & utility programs: All we need is the chosen sites 12-month 15-minute interval data in kW, kWh & tariffs to do a financial analysis What is a microgrid? An integrated energy system consisting of interconnected loads and distributed energy resources which can be controlled as a single entity operating in parallel with the grid and/or in an intentional islanded mode. Benefits of a solar+storage+EVcharging microgrid Efficiency & Optimization Reliable Energy

Ability to proactively island from utility Preserve critical loads 24/7/365 Repurpose grid tied inverters for island mode operation Determine root cause of outages and restore power quickly Minimize energy costs through fuel switching and energy savings Harness combined heat and power, maximize incentives Prioritize critical loads Monetize energy flexibility with the grid Green Energy

Incorporate low cost solar, low emission DER Implement net-zero projects Reduce green house gases 1. Financial analysis: historical usage modeling Step 1: Understand current onsite Cost of Energy and consumption profile by analyzing bills, tariff structure, and interval consumption data Integrate electricity supply/ delivery tariffs with the load profile into Homer Create graphical

representation of current cost of energy 2. Financial analysis: costs of solar+storage plus energy/power costs Step 2: Estimate the value of PV + ES by economic optimization Integrate the CAPEX of PV+ES at this site, informing the model of the value of PV+ES Step 3: Sizing of PV + ES + other components of the system Optimization based on the value of PV+ES to get value to get optimized energy/power values If site includes resiliency or ancillary services, requirements loaded into Homer Step 4: Solve for the future cost of energy/power onsite Integrate electricity supply/delivery tariffs with PV+ES with the site load profile into Homer Homer outputs annual savings of energy/power with PV+ES 3. Financial analysis: paybacks with ISO & utility programs Step 5: Demonstrate savings from microgrid by loading data into proforma

Integrate the CAPEX of PV+ES at this site, informing the model of the value of PV+ES Step 6: Estimate the value of ancillary services Utilization of the battery is checked to account for savings/ancillary services and avoid double counting Ancillary services are then brought into the Financial Pro-Forma Hourly breakdown per year of Grid Purchases savings (Blue), PV output (Yellow), and Site Load (Red) Solar+Storage+EVcharging microgrid pencils financial analysis Note: SRECs not included in analysis Confidential Property of Schneider Electric Ideal space: North garage, Aquatics Center & Sports Pavilion Energy storage applications

Renewable Energy Generation Large End-Users Renewable Energy Shifting and Firming Charge the battery with excess of renewable energy during off-peak periods to release it onto the grid during peak periods, and possibly to follow a pre-defined generation pattern Renewable Energy Smoothing Charge/discharge the battery to smooth intermittent generation and follow soft power injection ramps. Electricity Rate Optimization Store electricity when the market price is low and consume it when the market price is high MicroGrids, Diesel Abatement Use storage in isolated grids in conjunction with renewable energy and fossil fuel sources

Ancillary Services Provide or absorb active power (respectively reactive power) in order to keep the grid frequency (respectively the grid voltage)within allowed boundaries Power Transmissio n and Distribution Investment Deferral Store Energy close to consumers during offpeak periods and release it during peak periods to avoid having to re-invest in new transmission or distribution lines Peak Shaving
