What happened
Since autumn 2026 an AI phone agent answers Stadtwerke Witten's hotline, handling monthly payment changes, meter readings, callbacks and tariff advice. It reads back amounts and meter readings for confirmation and hands structured requests to departments. The vendor reports about 50% of requests resolved during the call versus under 5% with the previous phone bot, after a few weeks live, and EU-hosted operation.
Why it matters
A municipal multi-utility example of billing and meter-reading AI with a reported (vendor) resolution rate, useful as a comparison point for US utilities considering voice agents.
Evidence and measured results
Vendor case study after a few weeks of operation; no method, call volume or error rate given.
Limitations and uncertainty
Vendor-authored, undated page, short live period; 'resolved' not defined. Included because it reports autumn 2026 live results in a thin subtopic.
Put this evidence to work
Lighthouse Advisory interpretation, grounded in this source. Enriched 2026-11-03; this does not change the original publication date. Each role follows the same checklist so takeaways compare across sources.
Sales
Role takeaway

Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Voice agent capturing structured requests and passing them to back-office departments; confirmation read-back reduces capture errors.
Governance
Who approves, reviews and stays accountable for outcomes?
Defines which transactions the agent may complete and hands off the rest.
Security and privacy
What data, permissions and controls need testing?
Caller identity and payment data handled by a third-party voice AI; EU data-zone hosting stated.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Offers 24/7 service; frees staff for complex cases.
Procurement
What should contracts, pricing and exit terms secure?
Specify resolution metric definitions and data residency in contracts.
Operating model
Which teams own the service once it runs?
Routine billing transactions move to the agent with structured handoff.
