General Services Administration

The General Services Administration (GSA) Blanket Purchase Agreement (BPA) is available to all government agencies authorized to lease or purchase vehicles from GSA Fleet. This includes most federal agencies but also many Native nations. You can use the agreement to procure a range of commercially available charging station options for level 1, 2, and DC fast charging, along with data subscription services.

EVSE purchasing resources include details about the BPA for EV charging equipment and integrating stations at your facility.

EV charging equipment vendors

Many companies offer equipment for charging EVs. Vendors in this space are continually changing and evolving; we will update this information often. The WA Dept. of Enterprise Services EVSE Contract # 04016 has an approved list of providers to assist your procurement needs.

A list of vendors is provided here.

As you work to identify state, federal, and utility financing opportunities to support EVSE procurement or hardware installation:

• Have a scope, timeline, and budget ready to go for when you find the right opportunity.
• Include any innovative elements or features that would make your project stand out in a grant competition.
• Connect with your electric utility to learn if your site has an adequate power supply for the EVSE you anticipate needing as you add EVs to your fleet. Keep these costs in mind when looking and applying for funding.
• Synchronize EVSE build-out with vehicle arrival. These projects can take 3 to 36 months.
• Consider shared purchase resources like Sourcewell Cooperative Purchasing or the Climate Mayors Electric Vehicle Purchasing Collaborative.
• Save time by referring to state contracts for Electric Vehicle Supply Equipment (Contract # 04016) and Motor Vehicles (Contract # 05916) provided by the WA Dept. of Enterprise Services.

EV charging is categorized by charging speed and power levels, and alternating current (AC) versus direct current (DC). The power delivered by utility equipment through transformers to buildings is AC. The batteries in BEVs store and deliver power as DC. AC power, common for moderate-powered charging, must be converted to DC using the vehicle’s onboard charger. DC fast charging (DCFC) equipment supplies DC power directly from the utility service to the vehicle batteries, bypassing the on-board charger.

The information provided here addresses:

• Charging speed
• Charging ports
• Charging specifications

The table provided here includes details to consider when planning to increase the number of vehicles that can share a single charging port. At first, it may be easiest to plan for one vehicle per EVSE port, but as facility staff gain experience with EVs, greater vehicle-to-port ratios will be more efficient.

The choice of non-networked or networked charging equipment typically balances the needs at each site with costs of equipment, software, and employee time. You can use telematics equipment attached to each vehicle or a networked charging system to gather data about the new EVs and charging systems.

The information provided here addresses:

• Non-networked systems
• Networked systems
• Telematics
• Load management
• Smart breakers
• Bidirectional, V2G, V2X, or V2B charging
• Open Communications Protocol (OCP)

Estimate the power demands for your new EVs to identify the number and types of EVSE or charging stations you will need for each location. The power demand is based on vehicle’s duty- and drive-cycles and the levels of charging required.

The information provided here addresses:

• Things to consider
• How much electricity will you need to charge the new EVs?
• Calculate the charging load profile

The information provided here addresses the need to:

• Determine charging station locations and layouts
• Assess power capacity
• Employ best practices

Contact your utility when you have preliminary plans for adding EVs and charging equipment to your facility. The utility may have an EV customer specialist who can address technical questions, confirm the new electrical usage estimates, or explain if they have programs or incentives to support fleet or workplace charging.

The information provided here addresses:

• Preparing for your conversation
• Questions to ask your utility
• Future-proof your plans

The information provided here addresses:

• Are public agencies required to charge for visitor & employee charging?
• How could EV charging models impact our fleet?
