Seeking to slash CO₂ emissions from its North American manufacturing operations, Honda has entered into long-term virtual power purchase agreements (VPPAs) for renewable wind and solar power that will cover more than 60% of the electricity that Honda uses in North America.

These VPPAs will enable Honda to fully offset the remaining carbon-intensive grid-supplied electricity being used in its Ohio, Indiana, and Alabama automobile manufacturing operations, and will help the company meet its voluntary carbon reduction goal. As a result of the deal, Honda is one of the top automakers globally in the adoption of renewable energy to power its operations.

Starting in fall of 2020, Honda will purchase 530,000 MWh/year from 120 MW of wind power generated by the Boiling Springs Wind Farm in Oklahoma, a 150 MW development of the energy company E.ON.

The Boiling Springs Wind Farm is E.ON’s first project in Oklahoma and in the Southwest Power Pool. The 150 MW project will begin onsite construction in early 2020 and be completed by the end of the year, and is part of more than 1 gigawatt of renewable wind and solar energy projects E.ON will deliver to the grid by the end of 2020.

In fall of 2021, Honda will secure an additional 482,000 MWh/year from 200 MW of solar power generated from a Texas solar facility. Additional details of the Texas solar facility will be disclosed in 2020 when it is nearer to completion.

Honda’s combined agreements for the output of 320 MW of renewable generation capacity will result in the purchase of 1.012 million MWh of electricity per year, making it the largest renewable energy procurement commitment for an automaker and one of the largest VPPA commitments in the US market.

Once fully operational, these VPPAs will offset more than 800,000 metric tons of CO₂e emissions annually—the equivalent of 100,000 US households worth of CO₂e emissions from household energy usage.

Honda will continue to purchase electricity from the local utility for each manufacturing facility, but will receive and retire renewable energy certificates (RECs) equal to the power produced through the VPPAs, resulting in net zero CO₂e emissions from electricity use within Honda’s Ohio, Indiana, and Alabama manufacturing operations. Currently, 21% of the electricity that Honda uses in North America is supplied from extremely low- and zero-CO2 sources. The VPPAs will raise the total use of renewable electricity to more than 80% for North America.

A virtual power purchase agreement is a way for Honda to purchase renewable energy in locations where it is unable to purchase renewables from the local electric utility. Honda agrees to purchase electricity from a renewable energy supplier, but the clean energy does not go directly to Honda’s facilities; instead it is sold into the electricity grid where the clean power is generated. However, Honda’s “virtual purchase” of renewable energy adds more clean energy into the nation’s electricity grid. This reduces the amount of electricity generated by fossil fuels, reducing the CO₂ emissions of using electricity.

In the process of structuring the Boiling Springs Wind Farm VPPA, Honda implemented an innovative contract structure with the potential to mitigate financial risks in the VPPA market, further expanding the market for corporations like Honda where reduced exposure to energy price risk is desirable. This new “collar” structure sets upper and lower bounds on Honda’s exposure to energy market price fluctuations in any given quarter, while resulting in strong and stable revenues for the renewable power operators.

These combined VPPAs will help Honda meet its CO₂ reduction goals by adding clean renewable electricity and by de-carbonizing the electricity grid. We hope the addition of a collar to the Boiling Springs project will encourage other companies to consider VPPAs as a method to secure renewable power and reduce climate-altering carbon emissions.

The wind and solar VPPAs are part of Honda's ongoing efforts not only to purchase renewable power but also to generate renewable power onsite at its North American operations. To date, Honda has installed 7.3 MW of renewable wind and solar power at its facilities across the region.
