EV numbers could jump from 2.4 million in 2021 to more than 26 million by 2030, and the number of public chargers has doubled since 2020. Yet many charging networks still sit far below their design capacity.<\/p>\n\n\n\n<p>This isn\u2019t just a policy or adoption problem\u2014it\u2019s an <strong>electrical infrastructure problem<\/strong>. As an electrical distributor, Dominion Electric Supply sees firsthand how design, equipment selection, and procurement decisions make or break EV charging projects. In this article, we\u2019ll explore why utilization lags, the technical and economic barriers behind it, and what contractors and developers can do to future-proof installations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Reliability Is the First Bottleneck<\/h2>\n\n\n\n<p>Public charging reliability remains the number-one reason networks go underused. A recent J.D. Power study found nearly <strong>1 in 5 charging attempts fails<\/strong> due to downtime, payment errors, or connector issues.<\/p>\n\n\n\n<p><strong>Electrical design solutions:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Specify UL-listed, field-swappable components<\/strong> that reduce downtime.<\/li>\n\n\n\n<li>Stock critical spare parts like cables and connectors to minimize outages.<\/li>\n\n\n\n<li>Use Dominion\u2019s procurement programs for faster replacements and warranty support.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Standards &amp; Interoperability Challenges<\/h2>\n\n\n\n<p>North America still uses three connector systems (CCS, CHAdeMO, Tesla\u2019s NACS), and protocol mismatches between EVs and chargers cause frequent failures.<\/p>\n\n\n\n<p><strong>Electrical design solutions:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Choose chargers that are <strong>ISO 15118 and OCPP-compliant<\/strong> for plug-and-charge readiness.<\/li>\n\n\n\n<li>Plan for NACS adoption by 2025 with adapters and compatible hardware.<\/li>\n\n\n\n<li>Dominion supplies load controllers, network gear, and panelboards designed for multi-standard compatibility.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Power &amp; Demand Charges Limit ROI<\/h2>\n\n\n\n<p>High-capacity DC fast chargers (DCFCs) create sudden load spikes\u2014up to 900 kW for a six-port site\u2014which can result in thousands in monthly demand charges.<\/p>\n\n\n\n<p><strong>Electrical design solutions:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Right-size the service and switchgear to balance peak demand.<\/li>\n\n\n\n<li>Integrate <strong>load management systems<\/strong> and energy storage (BESS) to flatten peaks.<\/li>\n\n\n\n<li>Dominion can supply the transformers, switchboards, and controllers required for efficient load balancing.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Site Layout &amp; Safety Matter<\/h2>\n\n\n\n<p>Many \u201cempty\u201d chargers are simply poorly placed. In rural or suburban areas, long feeder runs, lack of lighting, or inadequate signage reduce utilization.<\/p>\n\n\n\n<p><strong>Electrical design solutions:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Design with <strong>voltage drop in mind<\/strong> for long distances.<\/li>\n\n\n\n<li>Include bollards, area lighting, signage, and ADA-compliant layouts.<\/li>\n\n\n\n<li>Dominion offers complete takeoffs: conduit, wire, pull boxes, bollards, luminaires, and controls.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Economic Hurdles: L2 vs. DCFC<\/h2>\n\n\n\n<p>Level 2 chargers cost $2K\u2013$10K installed, while DCFC can exceed $150K each plus grid upgrades. Many sites struggle to justify these costs when average utilization is under 15%.<\/p>\n\n\n\n<p><strong>Electrical design solutions:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deploy mixed charging strategies (L2 for daily use, DCFC for highway\/fleet).<\/li>\n\n\n\n<li>Stage installations so infrastructure can expand without full upfront CapEx.<\/li>\n\n\n\n<li>Use Dominion\u2019s sourcing power to manage long-lead items like transformers and switchgear.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Rural &amp; Fleet Use Cases<\/h2>\n\n\n\n<p>Rural \u201ccharging deserts\u201d remain a challenge, but fleets (delivery, transit, municipal) are driving localized demand. Both require <strong>robust distribution infrastructure<\/strong> that can handle heavy duty cycles.<\/p>\n\n\n\n<p><strong>Electrical design solutions:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Design for higher duty cycles with oversized feeders, redundancy, and surge protection.<\/li>\n\n\n\n<li>Stock enclosures rated for outdoor\/rural environments (NEMA 3R\/4X).<\/li>\n\n\n\n<li>Dominion provides specialized gear for fleet depots and rural charging projects.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Procurement Playbook<\/h2>\n\n\n\n<p>The difference between an underutilized site and a successful one often comes down to supply chain readiness. Contractors can lose months waiting on panels, switchgear, or long-lead components.<\/p>\n\n\n\n<p><strong>Dominion Advantage:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>48-hour plan takeoffs:<\/strong> Send us your single-line diagram or site plan.<\/li>\n\n\n\n<li><strong>Stocking programs:<\/strong> Critical spares and consumables available on demand.<\/li>\n\n\n\n<li><strong>Value-engineered substitutions:<\/strong> Alternatives when lead times threaten your schedule.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>The EV charging crisis isn\u2019t about drivers ignoring stations\u2014it\u2019s about <strong>stations not being built to work reliably, efficiently, and profitably<\/strong>.
