米国調査会社ナビガントリサーチ（Navigant Research）の調査レポート「世界の自動車の電力網統合の市場分析と予測：グリッドサービスのプラグイン電気自動車管理」は、電力網サービスに使用される自動車の電力網統合（VGI）技術のビジネスチャンスを査定している。VGIの成長に伴う法規制の要因や影響を与えそうな市場促進要因と阻害要因について考察している。2030年までの世界のプラグイン電気自動車（PEV）、充電ポート、VGI容量、双方向充電器の市場を地域毎とタイプ毎に予測している。主要なVGI技術と主要企業について概説している。

The plug-in EV (PEV) industry is interested in vehicle grid integration (VGI) potential. The technology enables direct control of PEV charging, and in some cases, discharging. This capability has many potential uses. The most attractive have been to aggregate PEVs in grid service markets to protect distribution grids, integrate renewables generation, and decrease PEV owner energy costs.

Decarbonization drives VGI. This existential force is creating challenges for the automotive and electric power sectors, and VGI is a critical solution. Established automakers are being pushed to increase PEV production, which has proven costly and difficult to move. The electric power sector is pushed to adopt renewables that are difficult to integrate as a result of intermittency issues, and widescale adoption of PEVs presents threats to local distribution assets. VGI enables automakers to improve the economics of PEV ownership and the electric power sector to buffer intermittent resources to better meet grid demands and balance loads to protect the distribution grid. Although VGI is well-positioned to help solve these problems, industry must overcome significant technical and regulatory hurdles for the technology to succeed.

This Navigant Research, a Guidehouse company, report analyzes the market opportunity for VGI technologies to be used as assets in grid services. The study considers policy factors associated with the growth of VGI as well as significant market drivers and barriers. Global market forecasts for PEVs, charging ports, VGI capacity, and bidirectional chargers are segmented by region and location type, and extend through 2030. The report also examines the major VGI technologies and profiles key market participants.
