  1. may 2019 New England 2019 Regional System Plan (RSP19) Load, Energy and Capacity Resource Overview

  2. Summary • The Regional System Plan (RSP) includes system data, which is used in analyses supporting RSP and throughout the year. This presentation highlights current and historical system data • 2019 capacity data reflected in this presentation corresponds to the 2019-2028 Forecast Report of Capacity, Energy, Loads, and Transmission (CELT) • The CELT Report was posted on May 1, 2019 on the ISO website at: http://www.iso-ne.com/system-planning/system-plans-studies/celt • The 2019 CELT Report summer capacity ratings are based on the April 1, 2019 generator Seasonal Claimed Capability (SCC) Report Note: The SCC Report is located at https://www.iso-ne.com/isoexpress/web/reports/operations/-/tree/seasonal-claimed-capability

  3. 2018 Annual Net Energy for Load (123,430 GWh) • Notes: • Energy supply includes generation as well as 26 GWh of Demand-Response Resources (DRRs) • Net Interchange refers to the net of imports and exports • Pumping load is the load required to pump water into storage ponds • Net Energy for Load (NEL) is calculated as the sum of the energy supply + net interchange – pumping load • For 2018 the formula is: 103,730 GWh + 21,504 GWh – 1,804 GWh = 123,430 GWh • 2018 NEL is consistent with the value reported in the 2019 CELT • 2018 NEL increased by 1.8% versus 2017 with the energy contribution increasing by 1.1% and net imports increasing by 5.7% • Sum of percentages may not equal 100% due to rounding

  4. 2018 Energy Contribution by Resource Type • Notes: • The “Other Renewables” category includes landfill gas, biomass, municipal solid waste, and battery storage • DRRs are Demand-Response Resources participating in the Energy Market • As this chart does not reflect pumping load, the percentage of net interchange differs from the percentage of NEL shown on the previous slide • Based on Net Energy and Peak Load by Source posted at https://www.iso-ne.com/isoexpress/web/reports/load-and-demand/-/tree/net-ener-peak-load and primary fuel type of registered market resources reported in the 2019 CELT

  5. 2018 New England Generating Capacity and Energy • Notes: ▪ Capacity based on the 2018 CELT Report summer SCC values • ▪ 2018 energy is consistent with the 2019 CELT. The total energy reflects 26 GWh of DRRs that is not shown in the energy breakdown. • ▪ Capacity and energy values exclude imports and behind-the-meter generation not registered in the region’s wholesale energy markets. In 2018, the NEL was 123,430 GWh, pumped storage consumed an additional 1,804 GWh, and net imports were 21,504 GWh, which represents 17.4% of the 2018 system NEL.

  6. Interconnection with neighboring Systems

  7. 2018 Energy Imports and Exportsby External Area (GWh) • Notes: • Imports are shown as positive values and exports are shown as negative values • Data is based on the Net Energy and Peak Load by Source file

  8. Annual Net Energy Imports in GWh and % of System Net Energy for Load 2010 – 2018 Note: Since 2010, net energy imports increased from approximately 4.2% to 17.4% of the total New England net energy for load requirement.

  9. 2019 CELT RESOURCE CAPACITY

  10. 2019 Summer CELT Generating SCC Capacityby Primary Fuel Type (MW and Percent)Total = 31,242 MW • Notes: • Values include existing generation and expected capacity additions • Values do not include 954 MW of Hydro-Québec Interconnection Capability Credits (HQICCs), Capacity Supply Obligations (CSO) of 3,088 MW of demand resources, or 1,428 MW of capacity import and 100 MW of capacity export • The “Biomass/Refuse” category includes biomass and refuse (municipal solid waste, wood and wood-waste solids)

  11. Number and MW of Generating Unit Assets in New England – Summer 2019 by Fuel Type and In-Service Dates • Notes: • Generator assets in this table may be power plants or individual units that make up power plants • Values do not include HQICCs, demand resources or external imports and exports • Based on the SCC of the assets as reported in the 2019 CELT Report

  12. 2019 CELT Generating SCC Capacity* • by State and Load Zone *Values do not include HQICCs, demand resources or external imports and exports; totals may not equal to sum due to rounding 12

  13. ISO NEW ENGLAND INTERCONNECTION QUEUE

  14. Active Resources in the Interconnection Queue • Projects in ISO-NE’s Interconnection Queue as of April 1, 2019 • 177 generation projects totaling 19,047 MW • 26 wind projects ~ 11,239 MW • 14 are on-shore at 2,235 MW • 12 are off-shore at 9,004 MW • 118 solar projects ~ 3,319 MW • 8 dual fuel (gas & oil) projects ~ 1,937 MW • 5natural gas-fired projects ~ 1,152 MW • 13 battery storage projects ~ 1,209 MW • 2 fuel cell projects ~ 78 MW • 3 hydro-electric projects ~ 74 MW • 2 biomass projects ~ 39 MW Note: MW values shown based on project nameplate ratings

  15. Active Resources in the ISO Generator Interconnection Queue by State and Fuel Type (MW & %) • Notes: • Based on projects in the ISO-NE Interconnection Queue as of April 1, 2019 • The “Other Renewables” category includes biomass (wood) and fuel cells • The Energy Storage category only includes battery projects at this time • Out of the 3,089 MW of queue projects that are included in the natural gas category, 1,937 MW, or 63%, were specified as having dual-fuel capability in their interconnection requests. It was assumed that natural gas will be the primary fuel for those dual-fuel units • The totals for all categories reflect all queue projects that would interconnect with the system and not all projects in New England

  16. Active Resources in the ISO Generator Interconnection Queue by Fuel Type in Each Load Zone, by MW and Percent (%) of Total Capacity Notes: • Based on projects in the ISO-NE Interconnection Queue as of April 1, 2019 • Out of the 3,089 MW of queue projects that are included in the natural gas category, 1,937 MW (63%) were specified as having dual fuel capability in their interconnection requests. It was assumed that natural gas will be the primary fuel for those dual-fuel units

  17. Summer Capacity by Fuel Type (MW & %) Notes: • Capacity in 2019 based on 2019 CELT summer SCC values • The figure does not include net imports, active DR, energy efficiency, or behind-the-meter PV • 2022 breakdown does not show 5 MW of Energy Storage • Capacity in 2022 reflects the addition of Queue projects designated as "green" in the April 2019 COO Report as well as those Forward Capacity Market (FCM) Resources with Capacity Supply Obligations (CSO), and a reduction for retirements through the 2022-2023 Capacity Commitment Period • Capacity in 2028 assumes the commercial operation of all other projects (those designated as “yellow“) in the April 2019 COO Report • The capacity additions in 2022 and 2028 were calculated as follows: For FCM Resources, capacity values are based on Qualified Capacity (QC) for 2022. For non-FCM resources, on-shore wind is derated to 12% of nameplate capacity (based on an average ratio of summer SCC to nameplate for existing wind units), off-shore wind is derated to 30% of nameplate capacity, PV is derated to 34% of nameplate, while all other projects reflect the Queue net capability

  18. Generating Capacity Additions2000 – 2018 • Notes: • Other category includes oil, wind, solar, hydro and biomass/refuse resources • Capacity additions based on in-service dates and summer SCC values in the 2019 CELT Report

  19. Capacity of Generation Interconnection Requests by Load Zone (MW) • Notes: • Based on projects in the ISO-NE Interconnection Queue as of April 1, 2019 since Queue inception (Nov 1997) • Projects involving only transmission or that did not increase an existing generator’s capacity were excluded • Projects with more than one listing in the queue, representing different interconnection configurations, were only counted once
