Quick answer: the STEMIS EMS has completed both fronts of its BNDES accreditation. The hardware is accredited in the CFI System under code 04400903, and its software and firmware development has been validated. STEMIS is on the List of EMS Suppliers on BNDES's LRCAP 2026 page, alongside Automa, Micropower, Moura and Reivax. The STEMIS EMS therefore counts toward the local content index of projects in Brazil's national storage auction, scheduled for December 2, both as equipment and as software.

What was completed

  • Hardware accredited in the CFI System. The product "EMS hardware para BESS", model Grid Control Series US, holds CFI code 04400903 and appears in BNDES's public list of accredited products.
  • Software and firmware validated. BNDES's LRCAP 2026 page carries the List of EMS Suppliers for software and firmware project development: Automa, Micropower, Moura, Reivax and Stemis. According to the page itself, validated suppliers are published there.

As of November 9, 2026, four companies appear on both lists, with EMS hardware accredited in the CFI System and validated software: Automa, Moura, Reivax and STEMIS.

How we got here

  1. October 15: BNDES approved STEMIS's registration as a supplier in the CFI System. See BNDES approves STEMIS as a supplier in the CFI System.
  2. October 30: the EMS hardware received CFI code 04400903, as covered in The STEMIS EMS is accredited by BNDES.
  3. Now: validation of the software and firmware development is complete, and STEMIS is on the LRCAP 2026 List of EMS Suppliers.

Why it matters for project developers

The EMS is one of the strategic items in the local content requirement of the national LRCAP auction. Improving the local content index through the control layer avoids swapping the battery or inverter supplier, which is the most expensive thing to change once project engineering has advanced.
