Napa Green Land encompasses the whole property including the vineyard to the benefit of the Napa River Watershed ... This is a really strong program.

Wineries Save Time and Money with New Integrated Resource Assessments

Over the next year, 21 Napa Green wineries are on track to save a collective $84,000, thanks to the program's Integrated Resource Assessment (IRA) component. In the past, wineries had to go through three separate audits of their energy, water and waste systems in order to achieve certification and recertification – the one-stop IRA takes care of them all at once. This whole-system analysis identifies practical opportunities to save both resources and money.

Napa Green partners with Sustainable Napa County (SNC) on the assessments. The first step of an IRA is a simple energy rate analysis. Domaine Chandon was a huge winner, saving more than $60,000 with their rate change.

It was very rewarding working with SNC engineer Bill Bennett and Napa Green staff on the Integrated Resource Assessment. With their keen focus, we identified areas where we can improve our sustainability and save money. Through the PG&E/MCE rate analysis we were able to save over $60,000. They helped us plan for the future sustainability of our business.

Domaine Chandon's rate change savings was particularly high, but average savings for other wineries that qualified were more than $2,500 annually. That's money they can reinvest in other efficiency improvements.

Wineries can be recertified Napa Green every three years. Recertification requires continual improvement, including making gains in operational efficiency and investments in upgrades that reduce the amount of water and energy required to make each case of wine, minimizing waste diversion and reducing the winery's carbon footprint.

The Integrated Resource Assessments have not only been helpful in guiding our journey to Napa Green recertification, but they have also identified areas for improvement in our practices and efficiencies involving water, energy and waste. This translates both into cost savings and securing a more sustainable future. I highly recommend others take advantage of this opportunity.

The Napa Green Winery Integrated Resource Assessments are subsidized by PG&E and NVV so small to medium wineries only pay a matching fee of $200, while large operations pay a fee of $400, contingent on completing certification or recertification within three months. The custom assessment report goes beyond the program's requirements, identifying an array of opportunities that can be leveraged for immediate value.

It has been a great experience to realize we could save $4,600 a year without changing a thing. It's like magic money!

Tips for Improving Winery Efficiency


  1. If you aren't a part of the Napa Green program, consider attending an upcoming workshop. Subsidized Integrated Resource Assessments are available to NVV members only.

  2. Install a water meter and create a monitoring program. If no one is checking the meter, issues can easily go unnoticed for weeks.

  3. Check the pressure in your compressed air system to make sure it is not over-pressurized for your actual needs.

  4. Properly review and maintain your winery equipment according to manufacturer recommendations.
