Our editorial method

Our editorial approach is to explain the conditions that make a use case worthwhile, rather than presenting storage as a universal solution.

Sources and scope

We prioritise public bodies, grid operators and original technical documents. An overseas source can explain a technology without establishing its commercial availability in France. Relevant sources are linked from each article.

Facts, examples and estimates

Numerical scenarios state their assumptions. A hypothetical example is not a current tariff. We distinguish gross savings, fees and initial investment, and explain the limits of simplified calculations.

Updates and corrections

Articles show their publication date. Content changes update the revision date. To report an error, send the URL, the relevant passage and a source that supports your proposed correction.

Commercial interests

The initial site contains no affiliate links or sponsored content. If that changes, paid links and partnerships must be disclosed on the relevant pages. A commercial relationship must not be presented as an independent test.
