10. Location and Site Plan:
Provide site plan with approximate line routings for connection to nearby PowerStream facilities. The site
plan should include roads, concession and lot numbers and nearby power lines. It should identify the Point of
Common Coupling (PCC) location on the PowerStream feeder and the location (i.e. on private property or
municipal property) of all generator lines (collector lines and transmission / distribution lines).

e. If line tap required: Line tap between generating facility demarcation point (load break switch and
metering) and connection point on PowerStream’s feeder (PCC):

Note: PowerStream may request actual impedance for non-standard conductors at a later time.
f. PCC GPS coordinates:
g. Route distance from PCC (if distance from PCC to generator > 500m) to generation site:
km
h. Line tap to be built by:
PowerStream (see Note) OR
other (specify):
i. Line tap to be owned by:
PowerStream (see Note) OR
other (specify):
NOTE: Customers requiring line tap construction between their demarcation point and the connection point on the
PowerStream feeder should contact PowerStream to discuss potential ownership options, construction and coordination
logistics for these facilities. Also, those customers whom may require attaching collector lines to PowerStream poles
must also contact PowerStream to discuss potential to engage in joint use of utility assets.
PowerStream will consider owning and operating all new lines if they are designed and constructed to PowerStream
standards and are located on municipal roadway right-of-ways. This may change your PCC location. You must contact
PowerStream to discuss. For details email egconnect@PowerStream.ca or call 1-877-963-6900, extension 25001.
