Open-source energy models don’t replace utility tools in NA...yet. They help widening participation. Enabled shared assumptions, transparent methods, more eyes on the problem. That also improves policy, reduces surprises and leads to plans that hold up when tested.

The Achilles’ heel of BPS remains transformers. Little has changed since 2024. Lead times are still 2 to 4 years for standard units + up to 5 years for large ones. This is not a short-term supply issue; it’s a structural constraint being worsen by climate change.

Still producing at 80% after 30 years = confirms that module durability is not the main constraint on further solar expansion. At higher penetration, challenges are with inverter behavior, system controls + grid integration rather than panel lifespan. Need more investment on grid integration.
