A dated policy comparison. Not a government performance score or an official bill. Consumer rules are labelled reported where primary subsidy orders were unavailable.

Inspect the sources and assumptions

Public policy deserves
a public understanding.

Political arguments often start with a conclusion. TN Lens starts with a question: what does the evidence support, who is affected, and what changes when we choose differently?

Our purpose is to make rigorous policy analysis understandable and open to inspection. Simple controls sit above explicit calculations, dated sources, and visible uncertainty. You bring the questions and decide what matters.

Electricity, explained.

Start with something close to home: your electricity bill. Minnal, the TN Lens electricity lab, connects household choices with the wider power system.

See what is known.
Question what is assumed.

Evidence has a date and a source.
Primary documents and reported rules are distinguished. Missing evidence stays visible.
Assumptions are yours to test.
A model result depends on its inputs and boundaries. A scenario is not an observed outcome.
Comparisons share a baseline.
We hold consumption constant when comparing bills. A tariff snapshot cannot measure an administration’s overall performance.
Uncertainty is part of the result.
Supply profiles are illustrative; future cost bands depend on your assumptions. Read limitations alongside the charts.
