February 15, 2013 | Boston, ma Stephen J. Rourke VICE PRESIDENT, SYSTEM PLANNING Restructuring Roundtable Draft 2013 Energy-Efficiency Forecast
About ISO New England • Not-for-profit corporation • Created in 1997 to oversee New England’s restructured electric power system; regulated by Federal Energy Regulatory Commission • Regional Transmission Organization • Independent of companies doing business in markets; no financial interest in companies participating in markets • Major responsibilities • Maintain reliable operation of the electric grid • Administer wholesale electricity markets • Plan for future system needs
Energy-Efficiency (EE) Forecast Background
+1.5%per year Long-term Load Forecast Projects Demand10 Years Out • +0.9% • Per year Peak Demand Forecast 2012-2021 (megawatts) • Baseline forecast developed with: • State and regional economic forecasts • 40 years of New England weather history • Other factors: • US Dept of Energy projections of average retail prices • New EE standards for household appliances • Annual Energy Consumption Forecast2012-2021 (gigawatt-hours)
Energy Efficiency is a Priority in New EnglandRecent state EE spending and electric energy savings, 2009-2011 • Total NE states’ spending on EE in three-year period: $1.4B • Over $500 million spent in 2011 • Total reduction in electricity use: 3,905 GWh • About 1,580 GWh of electricity savings in 2011 • Total summer peak demand savings: 549 MW • Average annual summer peak demand reduction: 183 MW
EE in Forward Capacity Market • Annual Forward Capacity Market (FCM) auction commits resources to be available three years in the future • EE measures participate alongside generation • FCM provides a revenue stream that facilitates development of EE • 2012 auction procured resources obligated for 2015-2016 • 33,455 MW total capacity that will be needed • ~1,500 MW is EE • EE in FCM has more than doubled since 2008 Energy efficiency Emergency Generation Active Real- Time Demand-response
Energy-Efficiency Forecast Model Developed in 2012 • Previously, no well-established metrics for determining how much electricity will not be consumed in the future as a result of EE measures • ISO-NE developed a forecast of “EE savings”—how much electric energy will not be used—beyond the 3-year FCM horizon (2016-2022) • Forecast model based on future state EE budgets and amount of energy savings per dollar spent • Data provided by states and/or EE program administrators (PA’s)
EE Forecast Model General Assumptions • Annual budgets provided by the public utility commissions or representatives on their behalf are used in model • Sources of EE funding include: • System Benefits Charges • Forward Capacity Market • Regional Greenhouse Gas Initiative • Other • Production cost allowed to grow over forecast period • Based on the PA’s ability to spend growing EE budgets and potential for increasing production costs, ISO applied uncertainty factor to some states
2013 Energy-Efficiency Forecast Regional Results
Summary of 2013 EE Forecast • Draft forecast results are similar to the 2012 forecast results • Generally, when adjusted for the impacts of EE, forecasted energy use remains flat for the region • Reductions in energy use in VT and RI • Generally, demand reductions from EE slow peak growth rate in the region • Program performance changes from 2012 forecast • Regional production cost decreased slightly, resulting in an increase in energy reductions • Peak-to-energy-ratios decreased slightly, resulting in smaller demand reductions from equivalent energy reductions • Results vary by state
Regional EE Forecast Results(2016 to 2022) • Total projected spending on energy efficiency: $5.6 billion • Peak demand rises more slowly than with traditional forecast • Average annual reduction in peak demand: 188 MW • Total projected reduction over seven years: 1,314 MW • In VT, forecasted peak demand declines • Annual electricity consumption remains flat compared to traditional forecast • Average annual energy savings: 1,319 GWh • Total projected reduction over seven years: 9,233 GWh • RI and VT forecasts show declining annual electricity consumption
New England Results: Lower Peak Demand Growth, Level Energy Demand New England: Summer 90/10 Peak (MW) New England: Annual Energy (GWh)
Implications to the Power System • Timing of necessary transmission upgrades • Winter versus summer peak and energy impacts • Declining load factor; minimum load issues • Natural gas, nuclear, EE, DR, renewables • Will this be our system?
Conclusions • States continue to make large investments in EE • ISO-NE worked successfully with stakeholders to integrate EE data into ISO’s long-term planning & forecast processes • EE forecast shows the states’ investment in EE is having a significant impact on electric energy consumption and peak demand • VT/NH planning study: analysis revised with new resources & transmission and EE forecast indicates about $260 million of previously identified transmission upgrades deferred • For more information see www.iso-ne.com/eefwg
