System Reliability Procurement: Non-wires Alternatives in Rhode Island Tim Roughan National Grid
Origins – RI Legislation • Least Cost Procurement Law - 2006 • Intended to: • Increase stability through resource diversification • Integrate renewables • Reduce cost of energy • Increase accountability in planning and administration • Required the development of Standards for Energy Efficiency and System Reliability Procurements • Basis for 3-year EE plans • Approved in 2009 • Updated in 2011
Origins – RI Legislation • Despite approval of proposed SRP Plan in 2009, no SRP funding • Some EE budget money set aside for SRP analysis tool development • Internal guidelines for NWA consideration developed in 2010/2011 • EE/SRP Standards updated in 2011 • More detail in SRP section on funding, BC analysis and reporting • Incorporated project eligibility criteria from internal guidelines • Established annual reporting • First SRP Report was approved and funded in 2012
Our Internal Process • Internal Principles Document • Cross-functional agreement on NWA process • Approved in February 2011 • 2 Review Cycles (below) • If NWA options are available, wires and NWAs are considered together
Identified Need • Two Feeders out of Tiverton substation serving Tiverton & Little Compton • Forecasted to be overloaded starting in 2014 • Potential for ~5,600 affected Customers: 80% Residential, 20% C&I • Wires solution – substation upgrade – will cost $2.9 million in 2014 • Non-wires Goal: provide load relief starting in 2014, up to 1MW by 2017
Pilot Design – A Collaborative Approach • Project plan includes SRP and EE components • New technology, enhanced incentives, marketing and evaluation through SRP funding • Measures delivered through EnergyWise, the RI single family, residential audit program • Demand response events conducted through SRP funding • Benefit/cost analysis uses the Total Resource Cost model • Uses same avoided costs as the statewide programs • Added benefits associated with the DR events • Regional T&D deferral benefit is replaced with specific locational T&D deferral benefit as calculated as a revenue requirement for deferral years 2014 through 2017 • Associated benefits/costs of the leveraged EE components included in BC but not claimed by SRP • Pilot must be cost effective over full six-year life, not in each year
Preliminary Results to Date • 150kW load reduction needed in 2014. • This does not include savings from measures installed as a result of home energy audits completed in the area • 180 customers in 2012 • 83 customers so far in 2013 • Evaluation of pilot program will determine amount of resulting savings that are attributable to the pilot
