PPA Evaluation Tool: Introducing the Bidding System

Written by
André Morais

In the evolving energy market, connecting renewable energy producers with large consumers is crucial for building a sustainable future. At Synertics, we’ve developed the PPA Evaluation Tool to simplify and optimize this process. And now, we’re excited to introduce one of its most powerful features: the Bidding System.

This feature is designed to make negotiations for Power Purchase Agreements (PPAs) more transparent, efficient, and dynamic for both Generators and Offtakers.

How the Bidding System Works

The Bidding System in the PPA Evaluation Tool provides a structured environment where Generators and Offtakers can seamlessly negotiate PPA terms. Here’s how it works:

1. Generators Discover Potential Offtakers

Generators start by accessing a complete list of potential offtakers with activity in the country where their projects are located. This feature ensures they can quickly identify relevant buyers for their energy.

2. Submitting a Bid

Once the right offtakers are identified, Generators can submit a bid directly through the platform.
Each bid can be tailored with the following details:

  • Duration of the PPA (1, 3, 5, 10, 15, or 20 years)
  • Structure of the agreement:
    • Pay-as-produced: Offtaker buys the actual energy produced
    • Fixed Profile: A fixed quantity of energy is supplied regularly
    • Baseload Futures: A stable, pre-defined amount of energy is delivered continuously
  • Starting Date of the contract
  • Hedge Percentage: The share of generated energy to be sold through the PPA

Once submitted, the selected offtakers receive an email notification with all the bid details.
The bid also becomes visible in the Market Overview, allowing for greater transparency and market visibility.

3. Offtakers Respond with Counter Proposals

When Offtakers receive a bid, they can respond directly from the platform by submitting a counter proposal.

They have the flexibility to adjust:

  • The contract duration
  • The structure of the PPA
  • The starting date

Additionally, Offtakers provide key consumption data:

  • Annual consumption
  • Maximum hourly consumption

This information helps Generators better understand the Offtaker’s needs and evaluate the feasibility of the deal.

4. Negotiation and Bid History

Once counter proposals are submitted, Generators can view them all in a dedicated bid history area.
This organized view helps them analyze offers side by side, track negotiation progress, and make informed decisions, all in one place.

Why This Matters

The Bidding System transforms how PPAs are negotiated. By bringing all stakeholders together in a transparent, data-driven environment, it delivers several key benefits:
Faster Negotiations: Streamlined communication and structured proposals reduce back-and-forth.
Better Market Visibility: Both sides gain clearer insights into available opportunities.
Improved Decision-Making: Data-driven bids and counter proposals enable smarter, more strategic choices.
Stronger Partnerships: A transparent process builds trust and fosters long-term collaboration.

Conclusion

At Synertics, we believe the future of renewable energy depends on smarter collaboration between producers and consumers.
More than just a feature, the Bidding System within the PPA Evaluation is a step toward a more connected, efficient, and sustainable energy market.
