Why This Matters for Rural Electric Co-ops

Most co-ops have planned around flat load for decades. This report argues that assumption no longer holds, and it lays out how to prepare for medium and heavy duty vehicle charging before it arrives as a connection request. It is candid about why that is hard for co-ops specifically: limited capital, little in-house modeling capacity, and almost no local data on fleet transition timelines or charging patterns.

The cost of waiting is emergency upgrades under deadline pressure, and possibly losing a large commercial load to a co-op or utility that was ready. The report gives five concrete recommendations a co-op can work through in order, and it names the publicly available modeling tools (RMI's GridUp, EPRI's eRoadmap, NREL's EVI-Pro) that let a co-op start estimating where demand will land without buying software or hiring a consultant first.

Key Takeaways

Implementation Considerations

• Cost or Funding Requirements: The core recommendation is to upgrade transformers, substations, and distribution lines ahead of materialized demand, which means committing capital before the revenue exists. The report points to USDA Rural Utilities Service loans, CFC, CoBank, and Farm Credit Bank, and flags that many federal programs (if available) reimburse after the fact, creating cash flow gaps for co-ops with thin reserves.
• Staffing or Technology Requirements: Advanced grid planning and proactive fleet outreach both sit outside the capacity of many smaller co-ops. The report suggests leaning on G&T partners, lenders' technical assistance departments, and IT vendors such as NISC and Meridian, and it specifically calls for marketing and member engagement training so staff can approach fleet operators at all.
• Time-Sensitive Information: The report discusses New ERA and PACE as paused at the time of writing. These are no longer available to co-ops for new applications, so co-ops without an approved award should not plan around them, though the surrounding material may still be useful to those already holding awards. The report also notes these programs never covered end-use electrification such as EV deployment. The 2022 Class 8 truck cost comparison ($279,000 electric versus $150,000 diesel) is dated in a fast-moving cost environment and should be refreshed before use in board materials.

Notable Examples

• Great River Energy (MN): G&T co-op that co-develops DER, electric transportation, and cybersecurity programs with member co-ops through a cooperative planning council.
• Roanoke Electric Cooperative (NC): Launched Upgrade to $ave in 2015 and has enrolled more than 10% of residential members, lowering wholesale peak demand charges.
• Kit Carson Electric Cooperative (NM): Reached 100% daytime solar power, with community input shaping the community solar project.
• Ouachita Electric Cooperative (AR): HELP PAYS tariff program delivered more than $3 million in site-specific upgrades across 6% of members in five years.
• Midwest Energy (KS): How$mart, running since 2007, has invested more than $10 million across more than 1,700 upgrades.
