Enhanced Distributed Solar Photovoltaic Deployment via Barrier Mitigation or Removal in the Western Interconnection (Final Technical Report)
In 2017, the Western Electricity Coordinating Council (WECC) 2026 Common Case projected that distributed solar PV deployment in the Western U.S. would meet or exceed 16,106 MW of installed capacity by 2026. Of this total, 12,218 MW was projected to be deployed in California and another 3,888 MW was projected to be deployed across Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. However, WIEB recognized that barriers to distributed solar PV deployment could cause the region to fall short of these projections. WIEB identified three types of perceived barriers that might interfere with the deployment of distributed solar PV generation in the West, including: (1) interconnection barriers; (2) utility rate-design barriers; and (3) reliability barriers.

Implications of a regional resource adequacy program on utility integrated resource planning: Study for the Western United States
LBNL collaborated with the Western Interstate Energy Board and the University of Texas, Austin to investigate the implications of a regional resource adequacy (RA) program on utility integrated resource planning. This report is focused on an active policy discussion to develop a novel voluntary program to share capacity resource and improve RA in the Western Interconnection. This report identifies two RA components of IRP that will be highly impacted by a regional RA program: resource capacity accreditation and RA targets. There are at least four resources that will require specific attention for their capacity credit calculation: (1) variable renewable resources, (2) demand-side resources, (3) hydropower, and (4) contracts. It will then be necessary to decide on a RA target reliability metric (e.g., a planning reserve margin) that is at least the minimum requirement in IRPs to ensure consistency in RA requirement calculations. The report finds that load forecasting and transmission expansion analyses will be moderately impacted, but that most of IRP components will not be significantly impacted. The report includes (i) a review of traditional resource adequacy practices in IRP; (ii) a case study of an existing regional RA program that interacts with IRP (Southwest Power Pool) and (iii) an overview of the NWPP regional resource adequacy proposal that is the object of this work. This paper does not (1) advocate for or against a regional RA program for the NWPP, (2) make detailed design recommendations for this program, or (3) assess its benefits and costs.
