The study focused on the following Smart Grid aspects: current status, drivers, barriers, technologies and solution components, implementation schedules and challenges, corporate priorities, utility organizational involvement, funding, impact on procedures and processes, impact on organization staffing, international collaboration, role of governments and local organizations driving Smart Grid, and standards development.

 

Canada: Hydro-Québec – Control Center Benchmarking

As part of a control center consulting project, ESTA benchmarked 11 utilities for their procurement practices and 6 utilities for best practices for control center operational technologies. ESTA identified potential utilities, and after discussions with Hydro-Québec, approached the utilities for their interest in participating in the benchmarking. Utilities were given the option to either respond to a questionnaire or participate in a two-hour web meeting. ESTA prepared the presentations for the web meetings and facilitated the web-meetings.  All participants had the option of remaining anonymous since a summary of results were shared with the participants.

 

Canada: Hydro-Québec – Substation Automation Benchmarking

Among the various activities of this project, ESTA benchmarked 8 utilities for their digital substation practices, such as IEC 61850. ESTA identified potential utilities, and after discussions with Hydro-Québec, approached the utilities for their interest in participating in the benchmarking. Utilities were given the option to either respond to a questionnaire or participate in a two-hour web meeting. ESTA prepared the presentations for the web meetings and facilitated the web-meetings. All participants had the option of remaining anonymous since the summary of results were shared with the participants.

 

International: Confidential Client – Operational Technologies Benchmarking

ESTA undertook a survey of SCADA/DMS/OMS/GIS systems used by 22 Distribution Network/System Operators in Europe representing utilities in 18 countries. ESTA identified potential utilizes to survey and offered the participants the option of using a web-based survey tool or in-person interviews. ESTA prepared the presentations for the web meetings and facilitated the web-meetings. All participants had the option of remaining anonymous since the summary of results were shared with the participants.

 

International: Large Electric Utility – SCADA/EMS and SCMS Benchmarking and Market Studies

ESTA undertook benchmarking and market studies for SCADA/EMS, SCMS (Substation, Control & Monitoring System), and utility best practices. ESTA conducted a comprehensive benchmarking and market study based on industry research and available literature.

 

World Bank: A Book on “Practical Guidance for Defining a Smart Grid Modernization Strategy – The Case of Distribution”

This book describes how utilities can define their own smart grid vision, identify priorities, and structure investment plans. The guidance includes key building blocks for modernizing the distribution grid and provides examples of grid modernization projects. The book covers four levels of grid modernization based on levels of automation that currently exist at a given electric distribution utility and progressively more sophisticated levels of grid modernization that may be needed to accomplish the vision for grid modernization. Grid modernization level III, the highest level of modernization identified in this guidebook, deals with DER integration and control of demand response. A copy of this guidebook may be downloaded using the following link:  https://openknowledge.worldbank.org/handle/10986/21001.

 

World Bank: Development of Smart Grid Technology Roadmap Guidelines

ESTA was contracted by the World Bank for the development of Smart Grid roadmap guidelines and used these guidelines to develop a Smart Grid technology roadmap for a World Bank member country. The roadmap included SCADA/DMS, EMS, GIS, OMS, and other technologies.
