Fri nettleie (grid tariffs per operator)

Grid tariffs and capacity tiers per Norwegian grid operator (community effort).

The community dataset kraftsystemet/fri-nettleie collects grid-tariff structures (capacity tiers, energy charges) per grid operator as YAML on GitHub. Migrated to a Firebase Function with a Firestore TTL cache (24h) that ingests and normalises all YAML files for pricing/energy-efficiency apps and business insights.
