The business case for electric transport

Start with routes and charging

Purchase price, maintenance and residual value tell part of the story. The truck also needs to charge on time, within the site's available grid capacity. Use actual route plans and charging data in the calculation.

For a depot or charging hub, five factors need attention:

• Volume: how many kWh do you expect to sell or use yourself?
• Timing: when are vehicles parked, and what does electricity cost then?
• Power: which demand peaks occur, and what will the connection or an upgrade cost?
• Utilisation: how many vehicles use each charger, and how often is it idle?
• Evidence: which delivered kWh can you substantiate for ERE-E?

Include civil works, maintenance, energy management and any battery storage. Installing more chargers does not by itself increase charging demand.

Calculate net ERE-E revenue

Registering eligible electricity supplies in the REV can generate ERE-E. Units reward the renewable share of the electricity. Selling them can provide additional revenue.

Use expected unit volumes, a sale price and the costs of registration services, verification and sale. Test different assumptions for charging volume and price. Include a scenario without ERE revenue.

Own generation may qualify as fully renewable under specific conditions. A green electricity contract does not automatically make grid supplies 100% renewable for registration. Check the metering arrangement and evidence requirements before using a higher share.

Agree who may register the supply and who receives the proceeds. Reflect any discount for the carrier in the charging tariff as well. Two parties cannot each include the full amount of the same revenue in their budgets.

Add the levy and grants

The truck levy affects costs per kilometre. Use the rate for the vehicle concerned and keep temporary discounts separate from calculations for later years.

AanZET supports zero-emission truck purchases. Charging infrastructure has other schemes, such as SPriLa. Check application periods, budget and conditions. Keep grant applications separate from confirmed awards in your calculation.

PYK Power helps compare charging profiles, meters, EAN details, contracts and supporting documents with the financial calculation. This shows which ERE revenue can be substantiated and where data is missing. Arrange the missing measurement or agreement before relying on the income.
