About us
AD-1 software built by people who know energy from the inside
Deklara is a product of Limeon S.r.l., a 100% renewable electricity supplier based in Bressanone. We lived the problem of consumption declarations before writing the first line of code.
"We filled out AD-1 declarations by hand for years. We know exactly what wasn't working."

The problem we solve
Every electrical plant subject to excise duty must submit the AD-1 declaration to the Customs and Monopolies Agency (ADM). With Legislative Decree 43/2025 declarations became semi-annual — more frequent deadlines, more complex sections, penalties for mistakes.
Complex AD-1 sections
Up to 11 sections (A, B, C, E, G, H, I, L, M, P, Q) depending on the declarant type. Filled manually on PDFs, the margin for error is high.
Tiered excise calculation
Art. 52 TUA provides differentiated rates per consumption band. A home-made Excel sheet is not enough.
Deadlines every six months
H1 by 30 September, H2 by 31 March. Miss a single cycle and face penalties and interest.
Who is Limeon S.r.l.
Limeon S.r.l. is a fully renewable electricity supplier, founded in Bressanone (BZ) with the goal of making energy simple, transparent and affordable. We serve our customers nationwide at PUN-linked prices with zero spread.
Our internal platform — Limeon Core — automates 90% of operational processes. Deklara was born from this digital infrastructure.
Why we built Deklara
We compiled AD-1 declarations for years for Limeon customers. When Legislative Decree 43/2025 doubled the workload, we built a serious tool — and opened it to plant owners who want to handle submissions independently, at affordable prices.
Our principles
Transparency
Prices published on the website, no 'contact us for a quote'. You know exactly what you pay before signing up.
100% Digital
No PDFs to print, sign and scan. Every declaration lives in the portal, with history and audit trail included.
Always compliant
The Art. 52-53 TUA excise calculation is kept up to date. The semi-annual deadlines under D.Lgs. 43/2025 are already configured in the system.
