Support Subscription

The support subscription funds the continued development and maintenance of PyPSA and secures its long-term future as free and open-source software. In return, companies and institutes that rely on PyPSA gain access to PyPSA experts' time for technical support, accelerated bug fixing, and a communication channel to suggest directions for future development.

How it works

Every hour of our time for support costs €130 (net). For each support hour, we also allocate two hours to PyPSA maintenance and development. As more support is booked, more of it goes directly to support. From 10 support hours per month upwards, each additional hour is matched 1:1. Public research organisations, non-profits and organisations from the Global South receive 1:1 from the first hour. The maintenance share funds general, undirected work on PyPSA that we prioritise ourselves, not commissioned development. It is contributed to the public repositories and keeps PyPSA independent of any single funder.

What we offer

• Long-term assurance. Your subscription directly funds the lead developers' time maintaining PyPSA and ensures its sustainability for everyone.
• Ticket-based support. Submit questions about using tools from the PyPSA ecosystem, such as PyPSA, PyPSA-Eur, linopy, atlite and powerplantmatching. We can help you debug and resolve specific issues. Tickets receive a first substantive response within two business days.
• Technical calls. Subscribers can schedule calls with the team for in-depth technical discussions and guidance on modelling approach. Appointments are scheduled within three business days.
• Accelerated bug fixing. If your work is blocked by a bug in PyPSA, we treat that as a priority.
• Feature suggestions. Subscribers get a direct channel to suggest and discuss features for future development. We cannot promise to implement every request, but we can promise that we consider your requests.
• Transparent budget. Time is recorded in 15-minute blocks and every response states the time spent. Subscription hours are balanced over each quarter, so a quiet month offsets a busy one.
• Review. Subscribers can book additional time for detailed review of their work, e.g. methodology, implementation, tool migration, or reports, at €150 per hour. This audit service is only available to subscribers.

What we do not offer

• Custom model development. We do not develop or maintain custom private or public models for you; we want to support you building your own.
• Integration into company systems. We do not help with integrating PyPSA applications into internal systems and resolving firewall-related installation issues.
• Guaranteed delivery of specific features in PyPSA.
