EPRI, Palo Alto, CA: 2008. 1016905. iii PRODUCT DESCRIPTION This paper, prepared as part of the EPRI Energy Efficiency Initiative, provides a first-order quantification of energy savings and carbon-dioxide (CO2) emissions reduction impacts of a Smart Grid infrastructure. Results and Findings First-order estimates of energy savings and CO2 emission reduction impacts were quantified for five applications enabled by a Smart Grid: 1) continuous commissioning for commercial buildings; 2) distribution voltage control; 3) enhanced demand response and load control; 4) direct feedback on energy usage; and 5) enhanced energy efficiency program measurement and verification capabilities. In addition, first-order estimates of CO2 emissions reductions impacts were quantified for two mechanisms not tied to energy savings: 6) facilitation of expanded integration of intermittent renewable resources and 7) facilitation of plug-in hybrid electric vehicle (PHEV) market penetration. The emissions reduction impact of a Smart Grid, based on these seven mechanisms, is estimated as 60 to 211 million metric tons of CO2 per year in 2030. Challenges and Objectives This study is intended to provide utility professionals and policy makers with an understanding of the range of benefits enabled by a Smart Grid infrastructure, with a focus on energy savings and greenhouse gas emissions reduction. Applications, Values, and Use This analysis can help a utility frame a business case for a Smart Grid infrastructure, including an advanced metering infrastructure (AMI), which includes a robust set of societal benefits beyond the operational benefits normally considered. EPRI Perspective EPRI has been developing Smart Grid research for years through its IntelliGrid program. IntelliGrid has produced methodologies to guide utilities through the process of Smart Grid development, from conceptualization, definition of functional requirements, specification of applications, and design and architecture to roll out and deployment. This study is complementary to that constellation of EPRI Smart Grid research and is one of the first that attempts to quantify energy savings and emissions reduction impacts of a Smart Grid. Approach The project team prepared this report through secondary research of publicly available content, including EPRI literature, as well as consultation with industry experts within and outside of EPRI.

This paper reviews the current literature that refers to the development and exploitation of TES-based solutions in systems connected to the electrical grid. These solutions facilitate the energy system integration to get additional flexibility for energy management, enable better use of variable renewable energy sources (RES), and contribute to the modernisation of the energy system infrastructures, the enhancement of the grid operation practices that include energy shifting, and the provision of cost-effective grid services. This paper offers a complementary view with respect to other reviews that deal with energy storage technologies, materials for TES applications, TES for buildings, and contributions of electrical energy storage for grid applications.
