Sweden's ZigBee City

摘要

Goteborg Energi wrestles with the right AMI deployment decision and gets ahead of the curve. In 2004, the Swedish government began drafting new legislation that prompted Goteborg Energi (GE) to start considering different solutions for remote meter reading. At that time, the only developed solutions were based on either power line carrier (PLC) or, to a lesser extent, radio on proprietary or restricted frequencies. The investment cost for a relatively small undertaking of a project of this nature would be substantial, even considering the opportunity to drastically reduce the number of staff involved in manual meter reading. Even if the simplest and cheapest solution were selected, the return on investment would be poor and the overall return would be negative.
