  29. 29. Policy recommendations3
  30. 30. Regulatory Assistance Project (RAP)® • Prioritise implementation of CE4All package. • Energy component: Regulators to set EV tariff if needed. • Network component: Require time-varying tariffs. • Monitor effectiveness of tariffs. Smart pricing 32
  31. 31. Regulatory Assistance Project (RAP)® • Require smart functionality in all electric charging solutions. • In particular, require technology that enables the application of smart retail tariffs. • Define technical requirements to drive deployment of appropriate technologies. 33 Smart technology
  32. 32. Regulatory Assistance Project (RAP)® • Accelerate equipment at workplaces and MUDs. • Set ambitious and differentiated target requirements for future charging infrastructure. • Use existing transport and grid assets through joint planning. • Anticipate future charging needs for different use cases (electric HDV) via pilots. • Seek to increase the use of renewables. 34 Smart infrastructure
  33. 33. Regulatory Assistance Project (RAP)® 1. EV grid integration advances the clean power and transport transitions in parallel. 2. Policymakers on European, national and local level can address this opportunity jointly. 3. Start with smart tariffs, smart technology and smart infrastructure. 35 Conclusions
  34. 34. Regulatory Assistance Project (RAP)®  Start with Smart. Promising practices for integrating EVs into the grid  Beneficial electrification of transportation  Treasure Hiding in Plain Sight. Launching electric transport with the grid we already have Resources 36
