Project Update

The project team is currently finalizing construction related activities with Commissioning scheduled for May 2024. Once commissioned, the project will include 15 CCS, 3 MCS EVSE that can support charging of up to 21,000 Medium-Duty Heavy-Duty Plug-in Electric Vehicle (MDHD PEV) annually at full capacity using clean, low-cost electricity generated on-site.

The Issue

Medium- and heavy-duty (MDHD) vehicle electrification is beginning to accelerate but lacks the necessary infrastructure to support widespread adoption. Currently, adoption of MDHD PEVs has been limited to short-range and return-to-base operations. To increase adoption to longer-range vehicles and ensure equity among fleets that lack the physical and financial resources for onsite charging infrastructure, public charging options need to exist along major corridors. Since fueling is the largest component of a fleet’s operational cost, certainty around fueling is essential for a fleet to remain successful. These problems have not been solved in part due to the infant nature of the market but also because of the significant investment required to demonstrate a scalable DER package specifically designed to provide low-cost energy to MDHD PEV.

Project Innovation

The purpose of this Agreement is to fund the design, construction, and commissioning of a modular distributed energy resource (DER) package composed of solar, battery storage, and an AC/DC distribution control system at a public access electric truck stop. The scalable DER package will provide reliable low-cost renewable energy for a dedicated fleet of 10 to 30 Class 8 battery electric trucks as well as support broader public access MDHD PEV charging for fleets in a burgeoning trade corridor. By increasing the availability of public charging, this will stimulate MDHD PEV adoption and equity in adoption of these vehicles for the commercial sector.

Project Goals

Demonstrate an integrated DER package comprised of 5.2 MW solar PV array and 2.75MWhr/1.2MVA BESS that can be scalable.
Provide resilient supply of electricity to MDHD PEVs.
Evaluate system costs and savings within comparison to baseline, MDHD PEV performance and operational energy requirements.

Project Benefits

The integrated DER-supported charging infrastructure will be operated as an island, allowing for reliable, affordable, zero-emission public access and fleet charging of medium- and heavy-duty electric vehicles. The DER system will produce all of the power needed for customer charging, mitigating impact of time-of-use rate changes and potential public safety power shutoffs.

Greater Reliability


HWY65/Bakersfield site Distributed Energy Resource (DER) depends on a self-generation strategy without any grid interconnection. On site solar deployment of 5.2MWdc with 3.6MVA inverter along with 2.75MWhr/1.2MVA battery energy storage system (BESS) is utilized to create an islanded/microgrid operation. This system is isolated from the utility/grid connection, relying primarily on the BESS inverter (PCS) to create a virtual grid following operation.

Energy Security

Energy Security

An Energy Management System (EMS) is utilized for site control and operation of the microgrid, ensuring that the virtual grid stays active after initial start-up.

Lower Costs


The LCOE has been calculated as $0.238/kWh using the unmanaged charging with no DERs, and after applying charging management and DERs, the LCOE reduces to $0.145/kWh, which is a $0.094/kWh improvement over the baseline case.

Environmental & Public Health

Environmental Sustainability

The project will achieve significant emissions reductions through both its dedicated fleet as well as through public charging.

Consumer Appeal

Consumer Appeal

The ability to offer low-cost renewable energy to a dedicated fleet of electric trucks and broader public access MDHD PEV charging, which can potentially appeal to environmentally conscious consumers looking for sustainable transportation options.

Economic Development

Economic Development

The project can potentially stimulate economic development by creating new jobs related to the design, construction, and commissioning of the DER package and associated infrastructure. In addition, it can promote the development of local renewable energy resources, leading to increased economic activity and investment in the area.



The project can potentially promote equity by expanding access to affordable and reliable renewable energy for underserved communities, particularly those located in the trade corridor. Additionally, by showcasing the benefits of fleet electrification and providing cost savings, the project can potentially increase opportunities for small and minority-owned businesses in the transportation industry.

Increase Safety


By testing the new technology of Li-ion EV batteries and promoting off-grid resiliency, the project can potentially increase safety by ensuring that the fleets have access to reliable and uninterrupted power supply in case of power outages and minimizing the risk of fire incidents associated with battery storage.
