Abstract
California’s climate policies are accelerating the transition to zero-emission vehicles, but the construction sector faces a major barrier: access to reliable power at job sites. While electric excavators and loaders are entering the market, many construction sites—often temporary and in remote or constrained locations—lack the electrical infrastructure needed to support them. Grid connections are often too costly and take too long to install for construction projects, and existing grid infrastructure was not designed to handle the power demand of heavy machinery. Without practical charging solutions, electrifying the construction sector may lag behind state goals. Meanwhile, construction equipment is contributing 1% to 2% of California’s total greenhouse gas emissions. To better understand these challenges, the research team reviewed existing research, assessed available charging technologies, and spoke with utilities and energy providers across California. The research focuses on identifying key barriers and practical pathways to support construction electrification.
