EV Charging with Time-of-Use Tariffs in Israel: How to Save 30–50%

Time-of-Use (ToU) tariffs — known in Israel as Ta'arif Ta'o'z (תעו"ז) — are one of the most powerful tools available to EV owners for reducing charging costs. By shifting charging to off-peak hours, you can cut your electricity bill for EV charging by 30–50%. Here's how it works and how Greems automates the savings.

What Is a Time-of-Use Tariff?

Israel's national electricity company (IEC) offers a ToU tariff option that charges different rates depending on the time of day. Peak hours (typically daytime and early evening) are significantly more expensive than off-peak hours (late night to early morning). The principle is consistent: charge at night to pay less.

The Savings Potential

On a standard tariff, charging a 60kWh EV might cost around 35–40 NIS. On a ToU off-peak tariff, the same charge could cost 20–25 NIS — a saving of 30–40% per session. For a driver charging 4–5 times per week, this adds up to 3,000–5,000 NIS saved per year on electricity costs alone.

How Greems Automates ToU Optimization

With a smart OCPP charger managed through Greems, you don't need to manually start charging at midnight. Greems lets you set a departure time and a minimum charge target — the platform automatically schedules charging during the cheapest tariff window, finishing just before you need the car. Fully automated, zero effort required.

ToU for Fleets

For fleet operators, ToU optimization at scale delivers substantial savings. Greems manages scheduled charging across all vehicles simultaneously — ensuring the fleet is always ready by morning while minimizing energy costs across every site.
