Process for Assessing Energy Generation Potential in Metro Vancouver’s Water Transmission System

Description:Metro Vancouver is a regional government responsible for delivering essential utility services, managing growth, protecting air quality and green spaces, and providing housing and park services. Metro Vancouver's comprehensive Sustainability Framework includes several corporate targets including: to be carbon neutral by 2012, and to be a net contributor of energy by the year 2015. Efforts are underway throughout the organization to assess opportunities to reduce emissions and initiate capital projects to recover energy from Metro Vancouver's utility operations. Approximately, 1 billion litres/day of potable water is treated and supplied to Metro Vancouver's 2.3 million residents. The water infrastructure includes six dams, 22 distribution system reservoirs, 15 pumping stations, and approximately 550 kilometres of transmission mains. To meet organizational goals, Metro Vancouver has initiated an energy recovery study focussed on the extensive water transmission system. Nine sites within the water transmission system, where there is a need to reduce hydraulic pressure, were identified and assessed for energy recovery potential. It is expected that any electricity generated at these sites would be used to meet energy requirements at the site or sold to BC Hydro. This paper presents the approach used by Metro Vancouver to explore and understand the energy recovery potential in the water transmission system. Extensive collaboration between the operations and planning groups was required to address project objectives and meet operational requirements. The lessons from this study will be used to assess other sites for energy recovery opportunities.
