2017 Integrated Resource Plan – Studies

2017 Demand-Side Resource Potential Assessment

To improve the analysis, planning and delivery of demand-side management resources (DSM), the Company completes a systemwide study to identify the potential of demand-side management resources and their related costs over a 20 year horizon. The study is designed to assist with the planning and modeling efforts of our Integrated Resource Plan (IRP) and as a result is generally updated every two to three years for relevancy. Links to the 2017 study and related documents are below.

2017 IRP Flexible Reserve Study

The 2017 IRP Flexible Reserve Study (“FRS”) estimates the regulation reserve required to maintain PacifiCorp’s system reliability and comply with North American Electric Reliability Corporation (“NERC”) reliability standards as well as the incremental cost of this regulation reserve. The FRS also compares PacifiCorp’s overall operating reserve requirements, including both regulation reserve and contingency reserve, to its flexible resource supply over the IRP study period.

Planning Reserve Margin Study

The planning reserve margin (PRM), measured as a percentage of coincident system peak load, is a parameter used in resource planning to ensure there are adequate resources to meet forecasted load over time. PacifiCorp selects a PRM for use in its resource planning by studying the relationship between cost and reliability among ten different PRM levels, accounting for variability and uncertainty in load and generation resources. Costs include capital and run-rate fixed costs for new resources required to achieve ten different PRM levels, ranging from 11 percent to 20 percent, along with system production costs (fuel and non-fuel variable operating costs, contract costs, and market purchases). In analyzing reliability, PacifiCorp performed a stochastic loss of load study using the Planning and Risk production cost simulation model to calculate the reliability metrics for each PRM level.

Battery Energy Storage Study for the 2017 Integrated Resource Plan – August 2016

DNV-GL’s battery energy storage study provides PacifiCorp with a catalog of commercially available and emerging battery energy storage technologies with forecasts and estimates for both performance and costs. To further support PacifiCorp’s bi-annual IRP, DNV GL has produced probabilistic cost graphs for each of the proposed technologies, broken out by technology, energy conversion system, controls, and the remaining balance of system.

2014 Report on Irrigation Time-of-Use Pilot

Action item 7b of the 2013 IRP called for development of a pilot program in Oregon for a Class 3 irrigation time-of-use program.  PacifiCorp filed a report with the Public Utility Commission of Oregon on December 1, 2014 discussing the implementation and results of this pilot program.

2014 Wind Integration Study

The purpose of the Wind Integration Study (WIS) is to estimate the operating reserves required to both maintain PacifiCorp’s system reliability and comply with North American Electric Reliability Corporation (NERC) reliability standards. The WIS estimates the operating reserve volume, in addition to contingency reserves, required to manage load and wind generation variation in PacifiCorp’s Balancing Authority Areas and estimates the incremental cost of these operating reserves.

2014 Wind and Solar Capacity Contribution Study - October 2014

The capacity contribution of wind and solar resources, represented as a percentage of resource capacity, is a measure of the ability for these resources to reliably meet demand. For purposes of this report, PacifiCorp defines the peak capacity contribution of wind and solar resources as the availability among hours with the highest loss of load probability. PacifiCorp calculated peak capacity contribution values for wind and solar resources using the capacity factor approximation method as outlined in a 2012 report produced by the National Renewable Energy Laboratory.
