Project Highlights
- One 3.0 MWt and one 8.0 MWt Interim Energy Centre
- 1,300 trench metres of piping
- Design & Construction Support of 8 ETS
- At the full build-out OVDEU will service 5.5 million sq. ft. of space with a 21 MW peak load
Sewer Heat Recovery is the Future Low-Carbon Energy Source
The Oval Village District Energy Utility (OVDEU) is an innovative district energy system which currently uses two Central Heating Plants (11MW capacity) to provide heating and domestic hot water in Richmond, BC. The OVDEU currently reduces greenhouse gas emissions by an estimated 400 tons/year. This reduction will increase significantly in phase two, when the OVDEU will extract heat from a nearby sanitary sewer.
FVB Energy has been involved with the Oval Village project since performing the initial concept screening study, right through to design, construction support and operations support. As part of the initial studies, FVB investigated several sources of energy, including heat recovery from the Gilbert Trunk sewage line, from the Richmond Oval, from the Fraser River, CHP and biomass. FVB developed the most promising concepts and used technical and financial analyses to assess the viability of each option
In 2014, FVB updated the concept for the project, looking at the technical and financial feasibility of sewer heat recovery, and assisted Corix Utilities with completing their pro-forma by preparing AACE Class 4 cost estimates for several options for the Energy Centre, Energy Transfer Stations (ETS), Distribution Piping System (DPS), and Operation and Maintenance (O&M) costs.
FVB has performed the design and construction support for one 3.0 MWt Interim Energy Centre and one 8.0 MWt Interim Energy Centre. FVB has performed peer reviews on all buildings that reach the building permit stage in the service area. FVB has also performed the design and construction support for 8 energy transfer stations and over 1,300 trench metres of piping (2,600m of piping).
The deadline imposed by the first buildings to connect to the OVDEU meant there was no margin for error in scheduling, design, construction, or budgeting. FVB Energy was able to design and support construction for two separate interim plants (one containerized and one in a pre-engineered building), 200 trench metres of distribution piping, and two energy transfer stations in only six months. FVB worked closely with Corix and LIEC to integrate the design and construction of the district energy system with the design and construction of Polygon Carrera and Onni Riva Phase 1. This tight timeline meant that much of the equipment was procured while design was still being completed. Thus, as there was little opportunity for re-design, every aspect of the design had to be completed as efficiently and accurately as possible. Construction of the first phase was completed on time and on budget.
FVB Energy was the prime consultant for the entirety of this project completing, amongst other things, the screening study, due diligence study, concept development, peer reviews as well as design and construction support for ETS and DPS.
