This year marks a turning point for electricity as a transportation fuel for passenger vehicles. Automakers are sending electric vehicles (EVs) to market with global penetration forecasted to increase more than five-fold by 2016. The implications for electric power players and utilities are enormous, as the requirements of commercial EV adoption will inevitably burden existing electric power infrastructure. Given this reality, utilities are seeking out smart grid technology solutions to ensure grid reliability along with generation capacity by activating a digital dialogue between the grid and the EV.

Souce: GTM Research

This report examines in detail the technology and planning considerations that will enable a successful smart grid-EV convergence. The report analyzes hot button issues such as transformer build-out and advanced metering (AMI) and charging infrastructure, but also expands the conversation beyond these known challenges to highlight emerging smart grid solutions for the EV market. These solutions include communications standards and protocols that act as the "digital handshakebetween the grid and the EV, as well as distribution automation (DA) technologies that will enable a more self-aware grid capable of autonomously self-correcting based EV consumption patterns and moment-to-moment grid conditions.

Value-added Elements

  • Market, regulatory and cost drivers propelling EV adoption globally
  • EV sales forecast through 2016, with EV penetration by state for the U.S.
  • Analysis of EV planning considerations for utilities, including: charging impacts on load, substation planning, retail rate design, business case for EV integration, etc.
  • Strategic positioning of smart grid technologies (i.e., distribution automation, communications standards) for EV roll-out and grid reliability

Questions for Competitive Decision-making

  • How have global market trends such as gasoline prices, regulatory influence, and auto innovation positioned key EV markets?
  • Which global region will see the largest share of the EV market through 2016?
  • What will be the best utility practices for integrating commercial EV adoption into local grids?
  • Which smart grid technologies will see the greatest opportunity in the EV market and, how are these smart grid technologies already serving the EV sector?
