0441: Efficient Hydropower Outage Planning & Reporting - Phase 1: Assessment

Project Overview & Objectives:This project would be structured in two parts. The first part consists in the benchmarking of outage planning and reporting requirements, methods and tools. It would assess the best practices of outage planning and reporting among utilities, including internal and external communications, and available products and tools (including commercially-available Outage Management Systems (“OMS”) and optimization tools) that currently or could potentially support these t

7073: Low Carbon Case Studies for Residential and Commercial Space and Water Heating Using Air-Source or Ground-Source Heat Pumps

This study aimed to provide an improved understanding of the energy and greenhouse gas (GHG) impacts of a variety of heat pump (HP) systems based on a meta-review and analysis of field monitoring studies (case studies). Electric, natural gas, and dual-fuel (hybrid) air-source and ground-source HPs for space heating and domestic hot water were considered in residential and commercial applications. The ICF team also conducted literature searches and interviews with a variety of market actors to co

5083: LED Street Light Best Practice Guidelines for High Performance and Long Life Expectancy

The recent introduction of LED luminaire street lights represents a revolutionary advancement in street lighting, energy conservation, and environmental protection. This development was made possible by breakthroughs in high brightness white light LEDs that are now being produced with efficacies in the range of 100 lumens/watt. Some LED street lights presently in production have been designed to provide electrical energy savings upwards of 70% compared with conventional legacy street light tec

33132: Mitigation of Line Deterioration

The economic, reliability, and safety consequences of transmission line failure can be immense. Degradation of overhead transmission line components affects their electrical and/or mechanical performance over time and can ultimately cause component or line failure in service. The ability to respond to and manage these risks requires an understanding of the degradation mechanisms affecting transmission line components. Effective asset management also demands planning for the identification, evalu

3353: Methodology for Transmission Line Failure Investigations

Electrical utilities, all over the world, face transmission line failures caused by natural climatic or other manmade causes. Utilities can not prevent these random events nor can they afford to design transmission lines that would not experience failures. However, by conducting a thorough investigation after a failure event, to understand and establish the cause of failure in the transmission system, utilities can make improvements to minimize the likelihood of future failures. This report prov
