“Aggregating corporate buyers is a critical approach in transitioning to renewable energy, as it helps bring new capacity to the electricity market and opens up the market to smaller buyers. One of Cisco’s strategic sustainability priorities is to help accelerate the transition to clean energy, and we are proud to have played a leading role in negotiating and executing this deal in partnership with Sustainability Roundtable, Inc. and our six fellow offtaking companies.”

“Intuit is committed to delighting our customers and they have made clear they would like us powered by renewable energy. We have appreciated the SR Inc REPS team’s leadership in helping to create a model of shared services and buy-side aggregated VPPAs that has the potential to deliver cost-positive renewable energy for every enterprise that is creditworthy and able to make a long-term commitment to cause new renewable energy. It has made it possible to meet our goal of 100% renewable energy ten years early and to move to a more aggressive goal: climate positive ‘50 times by 30’ target that would result in a reduction of 2 million metric tons of carbon dioxide by 2030.”

Why Choose the NZCB as Your Trusted Partner in Decarbonization?

Since 2017, the Net Zero Consortium for Buyers (NZCB) has supported scores of industry-leading companies in the pre-construction financing of over 1.1 GW of new renewable energy globally through "the VPPA 2.0" - our proprietary buyer-favorable transaction process and structure. 

Our proven, buy-side-only reverse auction model eliminates conflicts of interest, reduces transaction friction, and delivers unmatched impact per megawatt procured.

Here’s what makes the NZCB different:
  • Zero upfront costs or exclusivity commitments to explore participation.
  • Multiple aggregated buyer-directed procurements year-round across North America, Europe, and now increasingly Asia, aligned with member demand.
  • Deals structured around Purchaser-Caused EACs (PC EACs)—not unbundled certificates or developer-led deal structures—so your commitment is unequivocally tied to net new capacity.
  • Through blind reverse auctions, developers compete for pre-financing commitments that are buyer-directed, not seller-led. Driving risk-adjusted outcomes and better-than-break-even procurement opportunities in many markets.
  • Smaller offtakes (5-50MWs) allow for diversification across multiple markets, technologies, developers, and timelines.
  • Through value-chain-aligned aggregated procurements (the VPPA 3.0), companies are embracing this solution as an elegant addition to their Scope 3 decarbonization plans.

Now, we invite you to join the next wave of innovation and leadership.
