Colorado Springs Utilities (CSU), a community-owned utility provides with natural gas, electricity, water and wastewater services in the Pikes Peak region of Colorado . Colorado Springs Utilities aimed to complete its Automated Meter Reading (AMR) project by 2010 [2, 3]. The successful completion of the AMR project in 2010 was a fundamental step in CSU's evolution to a multi-service smart grid. Through this AMR system and the associated Advanced Metering Infrastructure (AMI), CSU can capture reads for more than a half million electric, natural gas and water meters every day . CSU started the project in 2005 by awarding the contract to Landis+Gyr, and Cellnet+Hunt managed this project for the implementation phase . The AMR network is comprised of L+G Gridstream 902 – 928 mHz spread spectrum Radio Frequency (RF) Mesh Network . Later, an 'opt out' option was made available through which the customer's AMR meters are replaced with non-automated meters or AMR module is removed.
After the AMR establishment, Colorado Springs Utilities made plans to deploy some 1,900 smart thermostats and software applications from 2014-18, and the load-management program would be aimed at reducing load on distribution assets during peak power consumption. The thermostats would be equipped with Gridstream communications technology, notes Landis+Gyr, and would rely on the utility’s existing smart-grid network to communicate with sophisticated load-management software. During peak power events, the software would use accurate load information to determine the number of customer thermostats to control .
