Solar Technical Work Clause Samples
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.

Solar Technical Work. Prior to submitting the initial proposal for BP-20, Bonneville will put forth reasonable efforts to analyze and produce study results on solar integration in Bonneville’s Balancing Authority Area (BAA). This study work will include:
Solar Technical Work. As part of the workshop phase of the BP-22 rate case, and starting no later than January, 2020, Bonneville will:
i. Present to customers and stakeholders the costs and impacts of holding reserves in a non-flat shape, such as planned shaped diurnal reserve amounts. This presentation(s) will use the BP-18 Solar Integration Study with Solar modeling updates identified and implemented during BP-20 workshops to provide:
(a) Up to two shaped balancing reserve forecasts for all Generation Input customer classes (Wind, Solar, DERBS and Load).
(b) Forecasts for the different thresholds of installed solar generation in order to identify any meaningful thresholds where a shaped diurnal balancing reserve forecast or other form of planned shaped reserve operation becomes impactful and cost-effective.
ii. Analyze and present to customers any Generation Inputs variable and embedded cost allocation differences associated with a shaped balancing reserve operation, including the associated impact on Ancillary and Control Area Service rates. This analysis and presentation will:
(a) Assume that shaped balancing reserve held on Bonneville’s system is physically possible.
(b) Use a variation of the Generation And Reserves Dispatch (GARD) model or other balancing reserve variable cost estimation method to estimate any material change in Bonneville’s cost of providing balancing reserves associated with a planned shaped balancing reserves operation.
