The IRP is a long-term planning document designed to provide policy guidance for BWP’s electric supply to its customers over the next twenty years, from 2019 through 2038. The IRP, like all long-term planning, is directional rather than determinative. In other words, the IRP helps Burbank see the broad contours of its energy future and the general direction Burbank should head to reach that future; it is not a roadmap for decision-making beyond the near-term. The utility industry is undergoing dramatic change and this IRP reflects it. Concerns for climate change, the growth of cost-effective renewable energy and energy storage, and the pending retirement of one of BWP’s primary legacy energy sources, a coal-fired power plant called Intermountain Power Project (IPP), are all elements in the mix. At the same time, the IRP is informed by public input: what are the perspectives of Burbank residents, businesses, and other stakeholders with respect to Burbank’s energy future? BWP had a robust interaction with the public for this IRP, focused on major issues impacting BWP’s provision of reliable, affordable, and sustainable electric service to Burbank. This Chapter provides a brief overview of the highlights of the IRP, major changes in BWP’s business since its last IRP in 2015, proposed policy direction, and actions to fulfill that policy direction. The remainder of this IRP goes into greater detail on BWP’s business, both today and through the lens of long-term planning. Finally, detail on BWP’s public outreach can be found in Chapter 5. 1.2 Assumptions and Implications As a long-term planning document, the IRP is necessarily based on significant assumptions about the future: this carries inherent uncertainty, especially with the utility industry undergoing dramatic change. This IRP must make significant assumptions about a variety of key aspects of BWP’s business over the next 20 years, from federal and state policy direction to the availability of cost-effective renewable energy generation and electric transmission resources to the growth of electric demand in Burbank. With respect to generation and transmission resources, the IRP assumes that the economies of scale available in joint procurement with Los Angeles Department of Water and Power (LADWP) and others will remain. Also, for the purposes of this IRP, BWP forecasts little to no peak demand or energy growth over the next 20 years. This forecast is consistent with the California Energy Commission’s (CEC) forecast for the same period and reflects some (but not all) development under consideration in Burbank. Burbank Water and Power - 2019 Integrated Resource Plan Page | 7 The IRP is also based on Burbank’s and California’s energy policies. These include the “loading order”, whereby electricity demand is to be met first with energy efficiency and demand-side resources, then with renewable energy and then, to the extent that these are insufficient, with clean conventional electricity supply. These also include Senate Bill 350 (SB350) and Senate Bill 100 (SB100) which, among other things, mandate energy efficiency and renewable energy requirements for utilities like BWP. BWP, working with expert consultants, used those assumptions, public input, and legislative and policy framework to create illustrative views of Burbank’s energy future over the next 20 years. This complex analysis, referred to as “modeling”, yielded a number of major implications for Burbank’s energy future. These major implications are summarized here and discussed in greater detail in the body of the IRP.
