Connection Options Advisor
Compare network charges across HV and LV connection configurations with 5-year CIRP-based forecasts. Model up to 5 sites with custom Red/Amber/Green consumption splits to find the most cost-effective setup for new developments.
New connections have hidden cost differences
When planning a new connection, clients face choices: HV or LV metering, DNO or IDNO ownership, different capacity levels. Each choice affects ongoing network charges for years to come. But comparing them requires calculating charges under each scenario.
Use Cases

Quick Answers
“What is an IDNO?”
Independent Distribution Network Operators (IDNOs) own and operate electricity distribution networks, typically for new developments. They may offer different commercial terms than the host DNO.
