Doing Business with Calpine
As one of the nation’s largest and cleanest power producers, Calpine is committed to environmental responsibility, both for the company and our suppliers. Calpine purchases a broad range of products and services to keep our facilities running efficiently and cleanly.
Safety and Integrity at Calpine
Calpine’s commitment to safety and integrity – two of our core values – includes holding our suppliers to the same high standards we apply to our own operations.
- We make purchasing decisions based on many factors, including a supplier’s previous safety records. We also actively monitor our suppliers’ behavior at all our locations to ensure that they maintain Calpine’s safety standards.
- The integrity of our suppliers is also of great importance to Calpine. For more details, please review our Supplier Code of Conduct.
Calpine’s Purchasing Methodology
Calpine has a center-led procurement practice where purchasing decisions are made at the business-unit level based on research and guidance provided by its corporate supply chain department. Calpine’s supply chain experts identify and qualify suppliers across various purchasing categories to best fulfill the needs of our energy facilities and offices nationally and regionally.
The Improved Calpine Supplier Experience
In late 2023, Calpine implemented Coupa, a cloud-based purchasing and payment system that streamlines our shared workflow – all free of cost for our suppliers. Registration with Coupa is a requirement for all suppliers to transact with Calpine.

Calpine Purchase Orders & Invoicing
All new Calpine purchase orders will be sent electronically to suppliers through the CSP. Suppliers will send all invoices to Calpine though the CSP, supplier actionable notifications (SAN) or cXML. These are the most efficient methods to submit invoices, allowing Calpine to expedite payment in accordance with contract terms.
Invoicing Methods
- CSP: Suppliers create invoices directly from their purchase orders in the CSP with the click of a button, allowing them to manage all invoices and POs and view payment status. This is the easiest and most efficient method for suppliers seeking payment.
- SAN: Suppliers create invoices from a PO email, as well as the ‘create invoice’ webpage. Suppliers cannot see payment status via SAN and will need to log into the CSP to view invoices and POs.
- cXML: Suppliers who receive high volumes of purchase orders from Calpine will send cXML invoices directly to Coupa. Calpine has already identified and connected with these impacted suppliers.
- Suppliers who are unable to submit an invoice through any of the above options are asked to contact suppliersupport@Calpine.com.
Supplier Diversity – Powering Mutual Success
Supplier Diversity is an integral component of Calpine’s overall diversity, equity and inclusion strategy. Growing a diverse supplier base is equally as important as maintaining a diverse and inclusive workforce. We believe building strong relationships with local suppliers and small businesses who provide quality, cost-competitive goods and services is not only the right thing to do, but it’s good for business. Our Supplier Diversity program will continue to grow as we expand opportunities to diverse suppliers – building upon combined strengths to drive mutual success.
We are proud members of the National Minority Supplier Development Council, Supplier Diversity Advisory Council, the Houston Minority Supplier Development Council and the Women’s Business Enterprise National Council, which helps connect women-owned businesses to major corporations.
