Abstract

Similar to many U.S. utilities, Pacific Gas and Electric (PG&E) faces rapidly increasing local transmission and distribution expenditures and is developing a new local integrated resource planning process to limit these expenditures. PG&E is integrating demand-side management programs with local area expansion plans to reduce load growth and defer expensive local area transmission and distribution upgrades. We show how detailed load research data are used in the new local integrated resource planning approach. Integrating demand-side management programs in the traditional expansion plan enables PG&E to reduce its planned investment by 31% or $35 million in present value over a 20-year period, for a suburban area in Northern California.

An assessment model for energy efficiency program planning in electric utilities: Case of Northwest U.S.
2016, Sustainable Energy Technologies and Assessments
Energy efficiency stands out with its potential to address a number of challenges that today’s electric utilities face. These challenges include increasing and changing electricity demand, shrinking operating capacity, and reducing system reliability and flexibility. Being the least expensive and risky resource, share of energy efficiency programs in utilities’ energy portfolios has been on the rise since 1980 s and its increasing importance is expected to continue in the future. Despite holding great promise, ability to select and invest only the most prospective program alternatives plays a key role in successful use of energy efficiency as a utility wide resource. This issue becomes even more significant doe to the vast number of available potential energy efficiency programs, rapidly changing business environment, and the existence of multiple stakeholders. This paper introduces a hierarchical decision modeling framework which was used for the case of 13 high priority emerging energy efficiency program alternatives identified in the Northwest U.S. The results of the study revealed that energy savings potential (35.6%) is the most important program management consideration in selecting emerging energy efficiency programs. Market dissemination potential (25.7%) and program development and implementation potential (24.6%) are the second and third most important, whereas ancillary benefits potential (14.1%) is the least important program management consideration. Results imply that program value considerations (49.7%); comprising of energy savings potential and ancillary benefits potential; and program feasibility considerations (51.3%); comprising of program development and implementation potential and market dissemination potential; have almost equal impact on assessment of emerging energy efficiency programs.
The value of reducing distribution losses by domestic load-shifting: a network perspective
2009, Energy Policy
Shifting domestic load to off-peak time periods could potentially reduce electrical distribution losses and associated carbon emissions. This paper provides the first quantitative estimate of the possible reduction in losses, for a situation where domestic energy demand is shifted in time but not reduced. At a likely 0.02% of energy distributed by the network, the reduction is small relative to overall losses and to their variability, giving little rationale for distribution network operators in Great Britain to encourage such load-shifting for that reason. The paper also considers the limited regulatory incentives for the reduction, and the fragmentation of costs and benefits across different parties. The societal value is considerably higher than the current regulatory incentive, but nonetheless may still not warrant the cost of action. Reducing rather than shifting load is likely to give greater environmental benefits.
