The System for Input and Processing of Merchant's Information (informācijas ievades un apstrādes sistēma – SIPI) is a safe and convenient way for regulated companies to submit information - reports and documents in accordance with the legislative requirements.

To learn the opinion of stakeholders about a draft external regulatory enactment, a tariff proposal or other issues, the Regulator consults with public utilities providers and users, institutions, organisations and other stakeholders before adopting them.
