The underestimated external line
Building a charging station, the most underestimated cost is the 'external line'—the cable and transformer from the public grid to the site red line, often pricier than the stalls themselves. Good news: this bill is increasingly absorbed by the grid. Many State Grid branches extend the public grid to near the charging-site red line, the grid firm bearing outside-red-line electrical investment so project owners connect nearby and spend less. Shandong thus adds 100k kVA capacity, 100+ km lines and ~¥200M grid investment for its first 20 expressway heavy-truck demo stations; crucially it waives demand (capacity) charges for centralised stations, saving Shandong public stalls ¥2.9B in 2025.
Cost cuts in writing
Locals put 'cost cut' into plans. Chongqing's 2026–2028 charging-service action plan explicitly extends the investment boundary beyond the user's red line, applying 'three zeros (no visit/no approval/no investment)' and 'three savings'; Putian gives residential private stalls zero-approval, zero-investment low-voltage access with the grid fully funding pre-meter works—25 estates retrofitted in 2026; Linyi compresses single-source reply to 10 workdays, acceptance 3, energisation 3, and offers 'progressive' filing—build and energise in batches to ease upfront pressure.
Yantai's real relief
For Yantai operators and estate owners this is 'real-taels relief'. Dongdian Huichong's community and public charging reminds: when siting new public stations, proactively engage the State Grid 'one-site-one-plan' access and beyond-red-line investment policy to minimise external-line cost; old-estate residents should use the 'three zeros' benefit—pre-meter fully funded by the utility, not marked up by middlemen. Once the boundary extends, charging's last kilometre of 'affordable, connectable, usable' is truly opened.
