Summer Is Peak Season for the EV Charging Bill Most Sites Never See Coming

IPSWICH, Mass. – July 20, 2026– EV charging sites across the country are heading into the most expensive stretch of the year, and most operators don’t know it. Between June and September, many utilities raise their demand charge – the fee billed on a site’s single highest 15-minute interval of power draw – by 40% to 65% over winter rates. For a commercial site with EV chargers, a single unmanaged charging peak in July can set a surcharge that lands on every monthly bill through the fall.

EVready Energy, the turnkey EV charging partner behind the Energy Guardian platform, says the summer rate shift is exactly when active load management earns its keep.

“Demand charges are seasonal, and summer is when they bite hardest,” said Chris Nihan, CEO and Co-Founder of EVready Energy. “A DC fast charger can draw 150 kilowatts the moment a session starts. If that lands during your building’s afternoon peak in July, you’ve just set a charge that follows you for a month – at the highest rate of the year. Guardian’s job is to make sure that spike never registers.”

The platform’s impact is documented in a recent customer report. At Berger Chevrolet, a Grand Rapids, Michigan dealership, Energy Guardian managed ChargePoint and Blink charger loads against the building’s base consumption over a single billing period. Without intervention, the site would have set a peak of 149.8 kW; Guardian held the actual peak to 116.9 kW – a reduction that saved an estimated $680.94 in that period alone and cut the dealership’s single largest demand event by roughly 75%. Guardian intervened in only 7.1% of the period’s 15-minute intervals to do it, and no charging sessions were turned away.

“The Guardian software enables us to take advantage of opportunities to reduce costs, and the EVready Energy team is there providing friendly, expert guidance every step of the way,” said Mike Ohlman of Berger Chevrolet.

Energy Guardian is network-agnostic – it manages energy costs regardless of charger brand – and requires no equipment replacement. For commercial operators heading into the summer rate season, EVready recommends reviewing utility tariffs now, before the first heat-driven peak sets the tone for the quarter.

EVready Energy provides EV charging strategy, certified installation, and ongoing energy management for dealerships, fleets, multifamily properties, parking operators, and the public sector nationwide.
