BCUC - Stream A TES Application f or SSL-Sustainable Services Ltd. 2018-09-04
Stream A TES Application - Background:
Section 2.3 of the TES Guidelines state that two types of TES are considered by the Commission to be
Stream A Thermal Energy Systems. The second of these are "Any TES that does not meet the
requirements of an Exempt TES, without a CPCN or a CPCN exemption that has an in-service date prior
to August 28, 2014."
SSL was established in 2008 and began providing thermal energy as a municipal service through its
Community Energy System in 2010. Several years of planning, design and construction of infrastructure
preceded the system commencing operation, and as part of that, SSL requested a meeting with BCUC.
That meeting was held on June 3, 2008, between Brian Williston and Philip Nakoneshny of BCUC, and
Reg Stewart, Ryan McKenzie and Georgeann Glover of SSL, as well as two consultants working with SSL
on the creation of the system. A range of topics were discussed at that meeting, with SSL
representatives answering all of the BCUC representatives' questions, and the meeting did not result in
BCUC regulation of SSL.
We submit that the second basis for being considered to be a Stream A TES set out above exists for
situations exactly like SSL's where the thermal energy provider had commenced operation prior to
BCUC's Thermal Energy Guidelines being enacted. Not only is this the situation for SSL, representatives
of the company also went above and beyond simply determining whether BCUC appeared to regulate
thermal energy providers, and sought and attended a meeting with BCUC representatives to
ensure that it was in compliance with BCUC rules. We make this submission in support of SSL's
application to be considered a Stream A TES on the basis that it has an in-service date prior to August
28, 2014.

BCUC - Stream A TES Application for SSL-Sustainable Services Ltd. 2018-09-04
Location of TES facilities and description of site size. Include map or schematic diagram if possible.
The TES was established to provide heating and cooling services to end-users in the community of
Westhills in Langford, BC. SSL-Sustainable Services Ltd. ("SSL") delivers these services as part of a
Services Agreement with the City of Langford ("the City") and consistent with the terms and conditions
of Bylaw 1291, both of which define a contiguous Service Area within the municipal boundaries of the
City where the TES currently operates. Further details are provided in Appendices A and B.
Description of TES including energy centre and distribution system {drawing, diagram or description
of equipment, connections etc.)
The primary thermal energy source for the TES is a gee-exchange borefield consisting of 212 vertically
drilled wells combined into a closed-loop system. The gee-exchange borefield is located underneath
Goudy Field, which is part of an artificial playing surface and stadium complex owned by the City. The
TES also utilizes natural gas boilers as an energy source for backup and peak demand energy needs.
Finally, the TES is connected to Westhills Arena, a nearby ice rink facility owned by the City, which
provides supplemental energy to the TES in the form of waste heat generated by its refrigeration system.
Energy from the above-mentioned sources is routed through a primary energy centre which transfers
this thermal energy into a water-based distribution network. Each street within the service area
contains a pair of energy distribution mains, connecting all users to a common loop (similar to a water
system). Water is used to deliver heat to and from end-users because of its strong ability to store
thermal energy. The distribution network consists of two mains in every street: a "warm" pipe and a
"cool" pipe. The warm pipe contains water running at a higher temperature and is the main energy
source for space and domestic hot water heating. The cool pipe runs at a lower temperature and acts as
a cooling sink to remove heat and provide space cooling.
End users connect to the distribution network via on-site water-source heat pumps, which provide
functional heating or cooling to their buildings.
Describe system size and known energy demand.
Please refer to the "Load Forecast & Analysis" section (below) and Appendix B for details on system size and energy figures.
Description of whether system and or site is designed to be scalable and intended to connect to other
systems, buildings or locations.
The TES is broadly designed for scalability, as evidenced by its ability to expand from initially serving only
a handful of customers to its current service base of more than 400 connections. At this time, there are
no confirmed plans to scale the system beyond its current capacity.

Description of back up or alternative services available. Including information of provider.
In addition to the primary thermal energy source (geo-exchange), the TES also uses centralized natural
gas (FortisBC) boilers in its energy centre, along with a waste heat recovery system connected to a
nearby ice rink (owned by the City) . Most end user mechanical systems also include an electric (BC
Hydro) or natural gas (FortisBC) backup/heating component.
Any other information on service/energy provided and the scope of services and facilities.
SSL leases water-source heat pump systems to the majority of its end users. These systems are
designed to be compatible with the operating conditions provided by the overall TES. As part of this
arrangement, SSL is also responsible for the ongoing maintenance, repair, and eventual replacement of leased equipment.
While largely separate from the TES, SSL is also responsible for the delivery of potable water within the
Westhills Service Area. Water is provided under a similar structure to that of the TES, with SSL acting as
a service provider on behalf of the City in accordance with a local bylaw and Service Agreement.
Description of the use of municipal or public rights of ways.
SSL has installed infrastructure for the energy distribution system throughout the roads leading to and
within the Westhills Service Area. One such road, Lot D, is actually a titled lot (owned by the City)
making up a part of the Langford Parkway. There is infrastructure running under this road, including
two large distribution pipes, which is used to provide the Energy Service to the Westhills Energy Service
Area with no SRW or other charge in place formalizing SSL's rights to install such infrastructure nor
preserving SSL's ownership of this infrastructure. Similarly, as opposed to what is often the case for
major utility providers such as BC Hydro and Fortis, SSL and the City do not have a formal highway
license agreement in place for SSL's installation of Energy Service infrastructure in dedicated roads.
While the Services Agreement contemplated the granting of such an instrument by the City to SSL, it
was in fact never entered into by the parties. The attached Appendix Coffers a schematic plan showing
the areas where infrastructure is installed pursuant to a formal charge and areas where there is no such
formal charge or license agreement.
Name the customer(s) involved in the selection or signing of contracts.
N/A {Unclear what is being asked?}
Number of customers/end-users:
The TES currently provides service to 425 connections.
