systems that are confirmed as satisfying the stipulations of Eirgrid, SONI and National Grid. The best systems do even more; the data they record helps with optimising plant operation and supply quality, analysing performance and fault finding. A good monitoring system


should be robust and physically compact. It should accept inputs from standard current and voltage transformers, and it should feature powerful analytical facilities to generate derived parameters. Support for customisation is essential, as TSO requirements will undoubtedly evolve. The system must provide consistently high accuracy and have large, static, non-volatile data storage. Measurements must be precisely timed and the system must support the TSO’s favoured data delivery method. sub.net from eMS meets these


requirements and more. It is a scalable solution that can support more than 180 trend inputs, it is compact and has low power consumption. It is already being used in Ireland to support the


provision of ancillary services. This is significant as, according to Eirgrid: “The Ireland and Northern Ireland power system is already operating with one of the highest percentages of renewables anywhere in the world…allowing Ireland and Northern Ireland to lead the way in the integration of renewable generation.” Ancillary services help TSOs to


maintain the stability of the supply grid while meeting statutory requirements for supply voltage and frequency. Offering ancillary services is a valuable source of additional income for energy providers and the key to unlocking these benefits is flexible and dependable high-performance monitoring. This is readily achievable, but


to guarantee success it is vital to consult with an experienced supplier that fully understands the often complex issues involved, that offers proven technology and that provides solutions tailored to meet the exact requirements of each application.
