Connecticut Department of Energy and Environmental Protection
Connecticut Department of Energy and Environmental Protection is actively involved in programs promoting sustainable solar energy and storage incentives in New England. The state is implementing various initiatives for BTM solar in commercial, industrial, government, and residential sectors through programs like NET METERING, Virtual NET METERING, LREC/ZREC Auction, RSIP, and SHREC. Despite looming deadlines and challenges, there is a focus on renewable deployment with specific MW targets. The state aims to address the declining costs of clean energy programs both behind the meter and on the grid side to achieve its deployment goals. Public Act 18-50 outlines the design and requirements for a shared clean energy program in Connecticut, emphasizing cost-based rates for energy and RECs with auctions for energy and RECs by electric distribution utilities.

Renewable deployment from CT programs 400 350 300 250 MWAC 200 150 100 50 0 LREC/ZREC* RSIP* Section 6 Large Scale PA15-107 1(b) Small Scale PA17-144 Best in Class Operating Proposed *RSIP and Eversource LREC/ZREC data as of December 2018; UI LREC/ZREC data as of August 2018 Connecticut Department of ENERGY & ENVIRONMENTAL PROTECTION
Looming Deadlines 2018: No state-wide shared solar program following 2017 pilot 2018: Municipal filled its VNM bucket, state close 2018: End of LREC/ZREC 2019: SHREC hits 300 MW target 2020: Renewable Portfolio Standard ends Net metering costs not transparent or predictable revenues to projects risk being too high or low to achieve deployment goals at sustainable cost 5 Connecticut Department of ENERGY & ENVIRONMENTAL PROTECTION

Public Act 18-50 Commercial/ Industrial Government Residential Shared Clean Energy program DEEP designing program requirements 25 MW Class I Cost-based rate for energy + RECs Public Utilities Regulatory Authority unlimited Auction for energy + RECs Electric distribution utilities 50 MW solar 10 MW fuel cells 8 Connecticut Department of ENERGY & ENVIRONMENTAL PROTECTION
Outstanding issues Two customer options: Buy All, Credit All and a netting interval set by PURA (instantaneous, daily or sub-daily) How netting options pair with storage RECs bundled with energy, credits only to customers (no 3rd party payments) Future adders for energy system benefits Energy storage Location on the distribution system Time of Use rates or other dynamic pricing Other policy benefits Interim Rate opportunity? 9 Connecticut Department of ENERGY & ENVIRONMENTAL PROTECTION
DEEPs recommended action items for PURAs Grid Mod proceeding 1. Expand data collection on electric vehicle and renewable thermal technology load shape and flexibility 2. Open a proceeding to explore rate structures that encourage off-peak electric use and incent EV and RTT adoption 3. Quantify and transparently communicate the distribution system benefits provided by DERs 4. Conduct or expand pilots on solutions that can lower or meet peak demand, including active demand response and energy storage 5. Develop a transparent process for the EDCs to consider non-wires alternatives 6. Investigate costs and benefits of upgrading EDC communications and metering infrastructure, analytical capabilities, and billing and other back-end systems 7. Establish statewide data standards for cybersecurity and interoperability 8. Require EDCs to plan for integration of new beneficial electric loads 10 Connecticut Department of ENERGY & ENVIRONMENTAL PROTECTION
