BATTERY ELECTRIC BUS CHARGING INFRASTRUCTURE 2 OF 2 CITY OF SAN LUIS OBISPO
PROJECT MEETING MINUTES AKA ENGINEERING COMPANY
MEETING NOTES
· PG&E installed the largest transformer pad onsite which wasn’t assumed during proposal stage.
Project will not need to request larger transformer pad from PG&E.
· Project will request secondary cables to be installed with this project in the PG&E application.
· PG&E application will most likely be a work order process which reduces processing timeframe
and simplifies the PG&E process.
a. Worse case request would be larger transformer, but existing pad will accommodate for
this request.
· GECE needs supplemental information to confirm loading calculations and transformer design
parameters based on future capacity and charging timeframes of the transit yard.
· GECE requested a transit study if one is available from the City. Emma will coordinate with Alex
to see what information is available.
a. Eddie reviewed impacts of different service loading scenarios which may require a
service upgrade. GECE will coordinate with ChargePoint to review their equipment
loading parameters. Emma provided City contacts at ChargePoint. Eddie will reach out
to secure a meeting.
b. As part of the PG&E application an understanding of the service loading will need to be
provided. A simple file depicting bus recharging times, how many busses charge
concurrently, and times when charging occurs will need to be provided over a typical 24-
hr day (8 am to 8 am). PG&E will want to review worse case scenarios to determine
service availability and if upgrades are needed.
c. GECE recommended reaching out to Geoff Straw for information they used to develop
similar information for their RTA project.
· Design team did not foresee any issues with submitting within the 90% PS&E timeframe
assuming information for the site capacity and loading can be provided soon.
