Does my generator need to synchronise with the mains?
There are three options for running generators with Flexitricity: • Full parallel running – generators start, synchronise with the mains, and ramp up to a fixed output power. The mains remains connected while the generators are running. The local Distribution Network Operator (DNO) must give permission for this type of operation. It provides the maximum flexibility for Flexitricity operation, testing and maintenance, and generates the maximum revenue for you. • Short term parallel (STP) running – this mode is also known as “soft load transfer” or “bumpless transfer”. Generators start and synchronise with the mains, then ramp up power until the generator output equals the site load. The mains circuit breaker is then opened, and the site runs as an “island”. Stopping generators is the reverse process. The local Distribution Network Operator (DNO) must give permission for this type of operation. The DNO’s requirements may be simpler than for full parallel operation, but this mode does not
