Electric Vehicle Supply Equipment and Cloud-based Subscription Services

The Office of Sustainability and Resilience (OSR) in the General Services Department is responsible for guiding the implementation of the Strategic Energy Action Plan. SEAP goals are integrated across the City’s operations of 200+ municipal facilities, structures, and assets, with a range of uses including office, warehouse, storage, parking, vehicle maintenance, communication towers, and public safety.  Currently, there are approximately 103 Level II and one Level III City-owned EV chargers installed across the city.  These stations are Chargepoint Stations and are currently covered under a 5-year warranty and service agreement.

The City is currently studying 850 additional vehicles for near-term electrification and associated infrastructure needs.  The City is issuing this RFP for Electric Vehicle Supply Equipment (EVSE) and related Electric Vehicle Charging Software services to support the SEAP goals.

The purpose of this Request for Proposals (RFP) is to select an EVSE vendor for future EVSE procurements to support future charging needs.  The City of Charlotte would contract with the selected firm for the purchase of EVSE hardware and cloud-based subscription services.  The majority of installed EVSE will be for fleet charging.  There will be some need for publicly available chargers which will require the ability to accept payment.

The City is seeking to hire an experienced and qualified Vendor that can provide a turnkey solution of all equipment, corresponding software and networking, accessories, and warranties.  In addition, we will be considering inclusion of a maintenance services contract.

Solar Photovoltaic Systems Maintenance and Services

The Building Services Division of the General Services Department/Engineering and Project Management is responsible for maintaining a portfolio of approximately 180 buildings, including offices, fire stations, police division offices, and equipment shops, that house various City activities.  The City also maintains cultural facilities, including museums and arenas that serve as venues for sports, entertainment, and other events.  Contracts resulting from this RFP may be used by various City departments for needs across the entire City organization, including the Airport.

 

The City plans to contract with one or more companies to provide annual routine preventive maintenance and repair services, as well as services on an on-call as-needed basis (collectively referred to as Services), for solar photovoltaic (PV) systems currently in existence or under construction as listed in the table below.  Systems may be added or removed from the list in accordance with the City’s needs.  The City is seeking firms whose combination of experience and expertise will provide professional, timely, and cost-effective services to the City.

The Company will deliver to the City a plan for preventive maintenance and cleaning to ensure maximum efficiencies in the operation of all equipment per manufacturer specifications.  The preventive maintenance and cleaning plan will include, at minimum, the following tasks, which the Company will perform at all the specified City PV system sites within 30 business days of receiving a Task Order, and every eleven (11) months thereafter if authorized by subsequent Task Orders:

 

  • inspect generation meter and monitoring equipment;
  • validate display data accuracy;
  • verify that system production is accurately communicated via remote monitoring software (e.g. SolarEdge Monitoring Platform);
  • visually inspect PV system condition including all modules and any auxiliary equipment;
  • inspect solar PV system modules for any signs of degradation;
  • clean all solar thermal collectors (with low PSI cleaning and biodegradable cleaning products);
  • confirm inverter operating modes (standby; startup and on);
  • inspect and maintain blower intake filters and electronics section air filters;
  • verify proper fan operation on each inverter;
  • check the inverters heat sinks and clean as needed;
  • check inverter enclosure seals for damage;
  • visually inspect the condition of all inverter cables and connections, and roof-top exposed wiring and electrical connections;
  • confirm power supply and transformer output;
  • check module ground connections;
  • complete mechanical inspection of connections and wiring;
  • measure the torque of all electrical connections and re-torque as needed;
  • perform a complete array electrical performance verification including visual and mechanical inspection and string level electrical tests with Solmetric Analyzer;
  • inspect flashings and sealants at roof penetrations;
  • inspect racking with particular attention to major fasteners; corrosion or damage; array shifting from wind; and thermal cycling damage;
  • tighten any solar module mounting hardware as needed;
  • remove debris and any blockage of roof drainage around racking;
  • inspect for and mitigate any vegetation and pest activity; and
  • complete thermal imagery in support of diagnosing any potential and actual performance issues.
