Does flexibility allowed in modifying standard contractual terms to fit specific project needs?

The contract for Local Green Consumers participating in the CREAM Programme is based on standard commercial terms, does not allow for modifications and must comply with the Guideline.

What is the type of licenses required (e.g. generation license, supply license)? What are the circumstances under which energy is considered "free to grid"? Are there procedure for selling excess via NEDA, detailed registration and notification requirements? Please help to provide guidance on approved REC registries, platforms, or any local tracking systems recognized by ST. Is there any guideline for license application?
