Common use of Solar Technical Work Clause in Contracts

Solar Technical Work. By January 2018, Bonneville will study and produce analysis on solar integration in Bonneville’s Balancing Authority Area (BAA), though this is not a commitment to conduct a comprehensive integration study. The intent of Bonneville’s analytical work will be to enhance Bonneville’s current methodology and inform Bonneville and stakeholders prior to workshops leading to the BP-20 Initial Proposal. This analytical work will include: a. A focus on the unique characteristics of integrating solar energy generation in Bonneville’s BAA contrasted to that of wind energy in the Bonneville BAA. b. The creation of a robust synthetic solar generation data set representative of a prospective geographically diverse build out of solar generation in Bonneville’s BAA, forecasted based on the growth of Bonneville’s interconnection queue through FY2025 as it exists on July 1, 2017 and through utilization of the University of Oregon’s Solar Radiation Monitoring Laboratory datasets. c. Analysis of the impacts on balancing reserves necessary to integrate solar energy in Bonneville’s BAA with regards to solar scheduling best practices and geographic diversity benefits as shown in section 10(b) of this Attachment 1. Bonneville will also hold stakeholder workshop(s) regarding solar generation prior to the BP-20 Initial Proposal to discuss (1) potential actions that can be taken by generators and Bonneville to reduce the balancing reserve requirement, (2) solar rate design, (3) the impact of the variable cost methodology and the incremental standard deviation methodology on balancing reserves held, and (4) the potential impact of planned reserves held in shaped amounts.
