California
The seven scenarios include three core scenarios (which all align with the SB 100 goal of 100 percent carbon-free electricity by 2045) and four study scenarios (which are "exploratory analyses" that "examine outcomes outside the scope of the joint agencies' interpretation of the SB 100 policy" to provide general information to inform California's broader planning efforts). The three core scenarios include a main core scenario (which includes retail sales and state loads and assumes high electrification demand and full resource availability), a scenario that considers a range of demand sensitivities (i.e., demand scenarios or load shape), and a scenario that considers a range of resource sensitivities (i.e., candidate resource availability). The four study scenarios include: (1) expanded load coverage, (2) no combustion, (3) zero carbon firm resources, (4) accelerated timelines.
Maine
The report consisted of a series of strategies and sub-strategies proposed by the Maine Climate Council. It did not explicitly list multiple pathways considered to achieve Maine's climate and energy goals.
Massachusetts
The eight pathways consider a range of assumptions including: (1) all options, (2) limited offshore wind, (3) limited efficiency, (4) pipeline gas, (5) 100% renewable primary energy, (6) no thermal, (7) regional coordination, (8) distributed energy resources breakthrough.
Nevada
The report proposes a series of policy and strategic recommendations. Further pathways-based modeling analysis is necessary.
New Jersey
The New Jersey report considers nine scenarios, including two business-as-usual scenarios and seven hypothetical pathways. The business-as-usual reference scenarios include: (1) "no-current or prospective energy policies", (2) "existing policy except 2050 GWRA & 100% Clean Energy". The hypothetical pathways consider a range of assumptions, including: (1) a least-cost pathway (based on the "fewest constraints to achieve emissions and clean energy goals"), (2) regional deep decarbonization, (3) reduced regional cooperation, (4) retaining fuel use in buildings, (5) accelerating renewables and storage cost decreases, (6) retirement of nuclear and no new gas plants, (7) reduced transportation electrification.
North Carolina
The report proposes a series of policy and strategic recommendations. Further modeling analysis is necessary, but separate from the initial North Carolina Clean Energy Plan report.
Rhode Island
The four technological bookends are: (1) 100% land-based wind, (2) 100% offshore wind, (3) 100% wholesale solar, (4) 100% retail solar.
