The document discusses using electric vehicles to provide flexibility and grid services through vehicle-to-building bidirectional charging. It summarizes a pilot that demonstrated integrating EVs, buildings, and local energy generation through bidirectional chargers and an energy management system. The pilot showed reductions in CO2 emissions, energy consumption, and energy costs of 17.6%, 13.0%, and 16.0% respectively. However, challenges remain around technology maturity, business models, social acceptance, and regulation that need to be addressed for vehicle-to-everything solutions to scale. The plan is to deploy new pilots and work to include vehicle-to-grid capabilities in grid codes and standards.

Introduction
 CHALLENGE:
• The integration of Electric Vehicles (EVs) in
electricity grids and the increasing penetration of
renewable energy generation creates a big
challenge for the DSO
 SOLUTIONS:
• EVs are able to offer other services than mobility
itself when they are parked
• Use the potential flexibility of the load associated
to charging EVs
• Use vehicle-to-grid chargers (V2G) to benefit from
EVs discharging possibilities
 INNOVATIVE SMART ENERGY MANAGEMENT:
• The use of V2G chargers requires an adapted
smart management to exploit their potential
>90% time

Scope of the measure
 The scope of the measure is to demonstrate the integration of electric
vehicles, buildings, and local energy generation in cities through the
combination of:
 V2G chargers providing Vehicle-to-Building services
 On-site renewable energy generation (PVs) & storage systems in buildings
 Smart control by an advanced Energy Management System

Lessons learnt
Technology maturity: Technical challenges due to the
maturity of the technology. Limited availability of V2X-ready
EVSE and electric vehicle models.
Business models: Need for a re-design of energy tariffs to
better reflect the real-time value of energy and capacity in
the power system to achieve sustainable business models.
Social acceptance: it will be necessary to promote potential
benefits and address possible concerns, such as data
security or battery guarantees.
Regulation: Lack of regulations, V2X should be included in
grid codes and develop global standards for V2X technology.
Barriers to overcome for the upscale of the measure

Replication plans
The plan is to deploy new pilots
at European level in order to
continue improving V2X
solutions to fill the gaps between
the actual state of technology and
real market solutions.
Work to include V2X in grid
codes.
