Book Description
Integrated resource planning helps utilities and state regulatory commissions consistently assess a broad range of demand and supply resources to meet customer energy-service needs cost-effectively. Key characteristics of this planning approach include: explicit consideration and fair treatment of a wide variety of demand and supply options, consideration of the environmental and other social costs of providing energy services, public participation in the development of the resource plan, and analysis of the uncertainties associated with different external factors and resource options. Integrated resource planning differs from traditional planning in the types and scope of resources considered, the owners of the resources, the organizations involved in resource planning, and the criteria for resource selection. This report presents suggestions to utilities on how to conduct such planning and what to include in their resource-planning reports. These suggestions are based on a review of about 50 resource plans as well as discussions with and presentations to regulators and utilities. The suggestions cover four broad topics; the technical competence with which the plan was developed; the adequacy, detail, and consistency (with the long-term plan) of the short-term action plan; the extent to which the interests of various stakeholders was considered, both in public participation in plan development and in the variety of resource plans developedand assessed; and the clarity and comprehensiveness of the utility's report on its plan. Technical competence includes energy and demand forecasts, assessment of supply and demand resources, resource integration, and treatment of uncertainty. Issues associated with forecasts include forecasting approaches; links between the forecasts of energy use and peak demands; and links between the forecasts and the effects of past, present, and future demand-side management programs.

Book Description
As global energy systems electrify, long-term planning processes are evolving to allow flexible economic analysis and acknowledge rapid financial and operational transformation. State-level integrated resource planning (IRP) processes allow oversight of long-term electric utility resource planning. Yet, outdated rules, procedures, and practices may impede utilities in planning for a new energy future. Is the IRP process constrained by technical modeling decisions, when it ought to serve as a platform for stakeholders to shape optimal and just electricity system outcomes? This paper assesses the state of integrated resource planning to inform utility planners, commissioners, and their staffs, along with the array of advocates that participate in such proceedings. I employ a case study methodology to assess docket filings and other relevant materials in recent IRP proceedings for four major utilities in Michigan, Georgia, New Mexico, and North Carolina. Section 3 details modeling software selection and use for those four cases. Section 4 uses capacity value assumptions to illuminate the iterative process around establishing model input assumptions. Section 5 takes a broader view of nascent efforts to include equity and justice into IRP processes. Consistent commission oversight and robust stakeholder processes are integral to ensure that utilities' integrated resource plans reflect the pace of change in the U.S. energy sector. Policymakers can encourage advanced modeling methodologies (software, settings, and assumptions) through three channels: (1) written IRP rules, (2) commission procedure, and (3) intervention in utility processes. Furthermore, as equity and justice come to the forefront of utility planning, policymakers should consider intervenor compensation programs, energy justice assessments, and forms of public ownership to incorporate energy justice principles into the planning process.

Book Description
Our Masters Capstone Project is an Integrated Resource Plan (IRP) for Arizona's largest electric utility, Arizona Public Service Electric (APS). An IRP is developed by utilities to identify the optimal combination of demand- and supply-side resources needed to reliably meet forecasted demand for energy and capacity, including a planning reserve margin, over a future period. In addition to APS's obligation to serve the growing load in Arizona while minimizing costs, it is required by the state to adhere to the Renewable Energy Standard (RES) policy of 15 percent retail sales from renewable energy resources by 2025. The analysis described in the report aims to identify the optimal resource mix for APS to deploy to reliably meet the forecasted deficit and deliver 100 percent of its retail sales from zero-carbon sources by 2050, based on its recently announced goals. We analyzed three scenarios: Business-as-Usual (BAU), 100 Percent Clean Energy (Clean100) and 100 Percent Renewable Energy (RE100). The Business-as-Usual scenario serves as a reference, exploring what it would look like if APS only adhered to Arizona's current RES policy. The alternative scenarios explore two pathways to reaching zero carbon emissions electricity by 2050, using only carbon-free energy resources in Clean100 and only renewable energy resources in RE100. The results of our analysis show that while both alternative scenarios demonstrated the feasibility of a zero-carbon system, Clean100 provided the least cost pathway to achieving APS's zero-carbon electricity goal by 2050.
