WORKPLACE CHARGING
USE CASE 02
We all love a "win-win" situation, but what about a "win-win-win-win"? That's what's available to us when we're considering workplace charging which can create a win for the employee, the employer, the utility customers, and the broader community as a whole.
Arizona has over 125,000 registered electric vehicles as of 2025 according to Arizona Department of Transportation, up from about 35,000 in 2020 and growth is expected to continue. Sufficient charging infrastructure will continue to be one of the challenges for EV owners, and charging needs to be where the vehicles are. The ability to charge at your place of work can be a huge incentive for switching to electric. Daytime workplace charging can align with Arizona’s peak solar production creating a “good load” that supports grid efficiency. How can we make this happen?
Why is this Use Case 'In the Money'?
(What is the simple version of why the use case works operationally / financially.)
● Employers and property owners collaborate to install and maintain
workplace EV charging, supported by clear agreements and shared cost
models
● Workplace charging adoption leads to increase in employee EV use
● Local utilities, policies, and infrastructure support daytime charging
utilization for employee electric vehicles
● Toolkits enable non-technical decision makers to plan, budget, and
implement charging project changes
● Charging stations operate on renewable energy, and provide reliable user
experience
Obstacles / Challenges
(What are the main issues that need to be navigated in order to achieve the potential business value?)
-
Infrastructure and Technology
-
Lack of EV charging solutions for small fleets (<5 vehicles)
-
Extreme heat (110°F+) impacts on battery range
-
EV adoption as ‘vehicle swap’, unmet operational needs
-
-
Financial and Policy Conditions
-
High Upfront Costs
-
Limited resources for fleet optimization
-
Complexity deters decision-making
-
-
Stakeholder Engagement
-
Inconsistent stakeholder engagement
-
Delayed coordination = costly upgrades
-
Limited guidance for specialized technicians

Toolkit designed for midsize Arizona businesses, providing practical solutions
for installing EV charging infrastructure
● Overview of toolkit contents:
○ Guidance and problem-solving for EV installation
○ Scenario based pathways
■ Scenario 1: Owned Office Space
■ Scenario 2: Rented Office Space
● Format: PDF and or Google Doc
● Goal: to supply an easily accessible and comprehensive plan for EV
charging installation at workplaces that can be applied to the specific
needs and circumstances of a given property.
Case Studies
Recent case studies from 2024–2026 highlight that workplace charging has moved from a "nice-to-have" perk to a strategic tool for employee retention and sustainability.
-
-
MetLife provides one of the best examples of a large-scale corporate rollout across multiple campuses.
-
The Goal: To support a workforce where a growing percentage was shifting to EVs but lacked charging at home (urban dwellers).
-
The Result: They successfully installed Level 2 stations across their major U.S. hubs, using a shared-access policy to ensure turnover. They found that employees with workplace charging were 6x more likely to switch to an EV.
-
-
Hypercharge Case Study: Software Company (Free Model). A 2025 analysis of a North American software company showed how "Free-then-Fee" models manage charger congestion.
-
The Strategy: The company installed four Level 2 chargers. To encourage office attendance, charging is free for the first 3 hours. After 3 hours, a $25/hour idle fee kicks in to ensure others can use the spot.
-
The Result: 98% of sessions ended before the fee began, and employee satisfaction scores related to "office amenities" rose by 18%.
-
-
Regional Transit Agency: Paid Cost-Recovery Model. A transit company (documented in 2025) installed six Level 2 chargers for staff.
-
The Strategy: Since they did not subsidize gas for other employees, they opted for a paid model set to "cost-recovery" rates (covering electricity and maintenance only).
-
The Result: Over 2.5 years, the usage grew exponentially as staff saw the convenience of "fueling while working" at a lower cost than public fast chargers.
-
-
US Department of Energy: Federal Workplace Charging. The DOE has released a 2025 program guide based on the successful electrification of federal facility parking lots.
-
Key Insight: They recommend a "Charging as a Service" (CaaS) model for organizations that want to avoid upfront capital costs. This subscription model covers hardware, installation, and software for a flat monthly fee.
