The State of Hawaii Department of Transportation (HDOT) is a government agency responsible for the planning, design, construction, maintenance, and operation of Hawaii's transportation infrastructure. The agency is headquartered in Honolulu and has offices throughout the state. HDOT operates in the Regional Government sector and is committed to decarbonisation and the use of renewable energy sources to power its operations.

Decarbonisation is a critical goal for HDOT, as Hawaii has set an ambitious target of achieving 100% renewable energy by 2045. To meet this goal, HDOT has implemented a range of initiatives to reduce its carbon footprint and transition to cleaner energy sources. One of the key strategies is to increase the use of electric vehicles (EVs) in the agency's fleet. HDOT has set a target of converting 50% of its light-duty vehicles to EVs by 2025, and is working to install charging infrastructure at its facilities to support this transition.

In addition to electrifying its fleet, HDOT is also exploring the use of renewable energy sources to power its operations. The agency has installed solar panels at several of its facilities, including airports and harbors, to generate clean energy and reduce its reliance on fossil fuels. HDOT is also exploring the use of wind and hydroelectric power to further decarbonise its operations.

Corporate energy management is a key priority for HDOT, as the agency seeks to reduce its energy consumption and costs. To achieve this goal, HDOT has implemented a range of energy efficiency measures, such as upgrading lighting systems and HVAC systems at its facilities. The agency is also exploring the use of energy storage systems to help manage its energy consumption and reduce peak demand.

One of the most innovative initiatives that HDOT has implemented to support its decarbonisation goals is the use of corporate power purchase agreements (PPAs). A corporate PPA is a contract between a company and a renewable energy provider, where the company agrees to purchase a fixed amount of renewable energy at a set price over a specified period. HDOT has signed several corporate PPAs with renewable energy providers, which has allowed the agency to secure a reliable and cost-effective source of renewable energy to power its operations.

The use of corporate PPAs has been a game-changer for HDOT, as it has allowed the agency to achieve its renewable energy goals while also reducing its energy costs. By locking in a fixed price for renewable energy, HDOT has been able to hedge against future energy price volatility and reduce its exposure to fluctuations in the energy market. The agency has also been able to support the development of new renewable energy projects in Hawaii, which has helped to create jobs and stimulate economic growth.

Overall, HDOT is a leader in the decarbonisation of the transportation sector and is committed to using renewable energy sources to power its operations. The agency's focus on corporate energy management and the use of innovative solutions like corporate PPAs has allowed it to achieve its goals while also reducing costs and supporting the growth of the renewable energy industry in Hawaii. As the state continues to pursue its ambitious renewable energy targets, HDOT will play a critical role in helping to build a more sustainable and resilient transportation system for Hawaii.
