Expansion of solar investment and innovative renewable electricity solutions in collaboration with Shell Energy to set industry record for electricity generated through on-site solar


Napa, CA (May 9, 2023) - Treasury Americas, a division of Treasury Wine Estates Ltd (TWE), is expanding its on-site solar electricity generation through a substantial investment in renewable electricity, which will power each of its wineries. According to independent research conducted by globally recognized assurance and risk management provider DNV, Treasury Americas is estimated to be the leader of on-site solar electricity generation in the U.S. wine industry following the completion of the project.[i] Over 60% of Treasury Americas’ electricity will be generated by on-site solar upon completion of the project, setting a record for a U.S. wine company of its size and scale.

Every Treasury Americas winery will receive over half of its electricity needs from on-site solar generation. The project will involve the installation of approximately 13,000 solar panels across Treasury Americas’ properties, and when complete, the company’s total on-site solar generation will be approximately 14.3 million kWh annually[ii]. The project is pivotal in the company fulfilling its goals to transition to 100% renewable electricity by 2024 and net-zero carbon emissions by 2030[iii].

Expanding on a Pioneering Role in Renewable Electricity

Treasury Americas’ longstanding commitment to renewable electricity began in 2008 with solar installations at Beringer Vineyards. As part of this new investment, solar panels will be installed across iconic properties including Beaulieu Vineyard, Beringer Vineyards, Etude Winery, and Frank Family Vineyards in Napa Valley, as well as TWE’s properties in Paso Robles and the Central Coast. Sterling Vineyards—closed since 2020 due to damage from the devastating Glass Fire—is expected to reopen in the fall of 2023 fully powered by solar electricity.

“We have a responsibility to be stewards of the environment and to mitigate the impact of the climate crisis on our wines and communities. The rapid transition to 100% renewable electricity will eliminate the majority of our production emissions in only a few short years,” says Will Drayton, Director of Sustainability and Science for Treasury Americas. “Furthermore, additionality is key. By maximizing our on-site solar generation, we are greening the California grid and opening the door to future developments such as on-site storage.”

Going Beyond Solar

Treasury Americas has contracted Shell Energy Solutions to complete the project. To further support TWE’s global net-zero commitments, Shell Energy will provide additional solutions including management of the on-site solar generation as well as additional efficiency activities such as the retrofit of LED lighting and compressed air improvements.

“Collaboration is key to achieving decarbonization,” says Glenn Wright, Vice President of Renewables and Energy Solutions Americas for Shell Energy. “The work we’re doing with Treasury Americas is a perfect example of working together to figure out the right mix of solutions, which leads to achieving carbon footprint objectives. I’m proud of the strong relationship that the Shell Energy and TWE teams have established, and I am looking forward to continuing that into the future.”

[i] Based upon an April 2023 study in which DNV researched, analyzed, and estimated behind the meter (BTM) solar photovoltaic (PV) installation capacity (MW) of leading U.S. wine production companies with comparable levels of BTM PV installations as Treasury Americas. DNV’s methodology leveraged several key sources to identify and view PV installations for leading U.S. wine production companies and estimate the capacity of each solar array. Sources included public statements, press releases and reputable industry publications on the identified leading U.S. wine production companies; company websites, sustainability reports and job postings from the identified leading U.S. wine production companies; a third-party research database with over 100 million company records; and solar interconnection logs in applicable areas. Once DNV identified the locations associated with each company, the coordinates were entered into Google Maps, and PV Watts — a publicly available program from the National Renewable Energy Laboratory (NREL) — to verify the presence and estimate the capacity of on-site solar installations. Where possible, interconnection files from the Lawrence Berkeley National Laboratory’s (LBNL) Tracking the Sun (TTS) database were utilized to evaluate and confirm solar installations. DNV provided estimated figures and included headroom factors to account for under-representation of installed solar.

[ii] While all solar arrays are located on Treasury Americas properties, some arrays are financed through on-site Power Purchase Agreements (PPAs). Treasury Americas will purchase additional Renewable Energy Certificates (RECs) for approximately 10% of total solar generation where original RECs are unavailable.

[iii] TWE has committed to achieve net-zero carbon emissions by 2030 across scope 1 and 2 emissions. According to the United States Environmental Protection Agency, Scope 1 emissions are direct greenhouse (GHG) emissions that occur from sources that are controlled or owned by an organization (e.g., emissions associated with fuel combustion in boilers, furnaces, vehicles). Scope 2 emissions are indirect GHG emissions associated with the purchase of electricity, steam, heat, or cooling.
