\u201cWe want 20 charging points, but our main connection is too small.\u201d It is one of the most common questions during a site visit.<\/p>\n

The good news: in many cases, a grid upgrade can be avoided. There are four technical solutions.<\/p>\n

Four solutions without a grid upgrade<\/h2>\n

\n
01<\/div>\n
\n

Dynamic load balancing<\/h3>\n

The main connection is monitored continuously. When the building draws a lot of power (HVAC, production, office lighting), the charging power drops automatically. At night or at weekends, when the building uses little, full power goes to the chargers. More in load balancing: what and why?<\/a><\/p>\n

Key takeaway:<\/strong> no extra capacity needed, just a smart distribution of what is there.<\/div>\n<\/div>\n<\/div>\n

Peak shaving with a battery<\/h3>\n

A stationary battery of 50 to 250 kWh stores energy when it is cheap and releases it at peak moments. Especially interesting in combination with the capacity tariff<\/a>: you do not buy the battery just to charge, but to lower your peak power.<\/p>\n

Key takeaway:<\/strong> investment \u20ac20,000 to \u20ac80,000, payback typically 4 to 7 years, depending on your peak profile.<\/div>\n<\/div>\n<\/div>\n
\n

Integration with solar panels<\/h3>\n

A rooftop PV installation produces during the day, when the cars are there. The charger prioritises solar energy and only then switches to grid power. When that combination pays off is covered in chargers with solar panels and a battery<\/a>.<\/p>\n

Key takeaway:<\/strong> less grid load and a lower energy cost at the same time.<\/div>\n<\/div>\n<\/div>\n

Phased rollout with load profiling<\/h3>\n

Instead of installing 20 charging points straight away, you install 8 with monitoring. After 3 months, you know exactly how much simultaneous charging power is needed.<\/p>\n

Key takeaway:<\/strong> 60 to 70% of the theoretical peak power often turns out to be enough. That makes a grid upgrade unnecessary.<\/div>\n<\/div>\n<\/div>\n<\/div>\n

When a grid upgrade is still needed<\/h2>\n

If all these solutions fall short, typically with more than 50 charging points, a DC fast charger and heavy industrial consumption, a grid upgrade is unavoidable.<\/p>\n

\n
Lead time<\/span>6 to 9 months<\/strong>Plan it as a critical path, not an afterthought.<\/span><\/div>\n
Cost<\/span>\u20ac20,000 to \u20ac150,000<\/strong>Depending on the connection.<\/span><\/div>\n<\/div>\n

Considering a fast charger? Read a fast charger on your business site: 50 kW or 200 kW<\/a> first.<\/p>\n
