Background and Context

Context of 2018 Analysis In 2017, the Public Generating Pool (PGP) sponsored the Pacific Northwest Low Carbon Scenario Analysis, a study of alternative policies for achieving reductions in electric sector carbon emissions in the Northwest The original study can be found here: https://www.ethree.com/e3-completes-study-of-policy-mechanisms-to-decarbonize-the-electric-sector-in-the-northwest/ In 2018, follow-up studies were individually sponsored by three organizations to explore specific questions left unanswered by the original study Public Generating Pool Climate Solutions National Grid This document reports on the assumptions and results from these additional studies

Original Study Results: Cost & Emissions Impacts in 2050 Note: Reference Case reflects current industry trends and state policies, including Oregon’s 50% RPS goal for IOUs and Washington’s 15% RPS for large utilities

About the Additional Studies PGP sponsored additional studies exploring the means for and cost of achieving additional CO2 emissions reductions beyond the 80% goal assumed in the original study: 90%, 95% and 100% GHG emissions reductions with varying quantity and price of carbon-free biogas as a substitute for fossil natural gas Climate Solutions sponsored additional studies exploring 100% GHG emissions reductions: With and without biogas and small modular nuclear reactors (SMR), under alternative technology costs, and with a ceiling or “off-ramp” on compliance costs National Grid sponsored additional studies exploring the potential role for pumped hydro storage: Alternative assumptions about the cost of new pumped hydro facilities and new gas-fired generation, and accelerated coal retirement All scenarios assume revenue recycling

There are significant reliability challenges under a scenario without dispatchable thermal generation The scenario considers the effect of a 100% GHG reduction cap with only hydro upgrades, wind, geothermal, solar, and electric energy storage available as new resources Without dispatchable thermal generation capacity, it may be difficult to meet load under extreme weather conditions E.g., extended cold-weather period with low wind and solar production that occurs during a drought year This challenge would only increase under a scenario with significant electrification of building and vehicle loads to meet long-term carbon goals

There are significant modeling challenges under a scenario without dispatchable thermal generation The current version of RESOLVE was not designed to consider cases without some form of dispatchable capacity The model does not provide sufficiently robust examination of unusual weather conditions that drive the need for dispatchable capacity The model cannot consider multi-day energy storage as a potential solution to the energy constraints that are encountered The model does not consider land-use or other environmental limitations on resource supply or transmission capacity More study is needed to examine resource availability and transmission requirements More study is needed to analyze whether the system as modeled meets reliability expectations

Reliability analysis is needed for energy limited systems with high levels of storage as a capacity resource Thermal fleet retirements in 100% GHG reductions scenarios coupled with load growth create a need for replacement capacity to ensure resource adequacy In the alternative technology costs scenarios the primary source of capacity added is energy storage (pumped hydro & batteries) Storage provides capacity to help meet peak demands but does not generate energy that is needed during low hydro years or multi-day low generation events More study is needed to analyze whether systems with significant storage capacity as modeled meet reliability expectations The alternative technology costs scenarios meet the current reserve margin requirement with the addition of new energy storage (1 MW of 10-hr storage capacity is assumed equivalent to 1 MW of natural gas capacity) However, it is unclear how much energy storage can contribute to Resource Adequacy in the Pacific Northwest
