37 District Steam Service Tariff Changes Enabling Resiliency & Sustainability
Armand Agasian February, 2017 Enabling Distributed Generation Backup/Supplemental Service Tariff Changes
• Encourage development of smaller scale projects
• Promote sustainable and efficient generation technologies
• Reduce the economic and administrative burden
• Enhance customer experience
28 Enabling Distributed Generation Backup/Supplemental Service Tariff Changes
• SC4 Standby Rate Changes effective November 1, 2016 • Contract Demand (CD) focused in on December to March, inclusive • 2% bandwidth introduced for CD – Exceedance occurs when above bandwidth – Ratchet of CD then applies and bandwidth moves with it – Surcharge may apply • New multiplier for surcharge when applicable • Customers can lower the Contract Demand • Exemptions from backup/supplemental rate available
29 Enabling Distributed Generation Backup/Supplemental Service Tariff Changes
Exemptions: Designated Technologies: • Efficient CHP up to 1MW Nameplate rating of alternate energy • • Efficient CHP over 1MW, up to 15 MW source is <15% of maximum potential • Fuel Cells thermal demand. • Wind • Solar Thermal and Geothermal • Solar Thermal* • Photovoltaics Customers exempt from electric standby • • Sustainably-managed biomass rates. • Tidal • Designated Technologies Exemption • Geothermal* through May 31, 2019. • Methane Gas
30 Enabling Resiliency of Campus Systems Proposed Steam Interconnection Tariff Changes
• Increase flexibility to accommodate new applicants for steam service.
• Reduce the upfront financial burden for large projects such as campus systems.
• Enhanced customer experience during the interconnection process
31 Enabling Resiliency of Campus Systems Proposed Steam Interconnection Tariff Changes
• Changes proposed December, 2016
• PSC Review and Expected Approval – 2nd Quarter, 2017
• Upfront service prepayment requirements reduced or eliminated – 2 year revenue test increased to a 5 year revenue test
• Additional flexibility in determining point of service termination – Allows for service extension on customer property
