Postgraduate Diploma in Harmonisation and Filters in Transmission — studying from Ireland
Ireland's energy sector is undergoing significant change, with a growing share of wind power, expanding grid infrastructure and investment in interconnection and storage. The Electricity Supply Board (ESB) and Gas Networks Ireland manage major transmission and distribution assets, while EirGrid operates the national electricity transmission system. Engineers work on grid planning, renewable integration, network operation and energy system modelling. Regulation is provided by the Commission for Regulation of Utilities, with national targets set by government climate and energy policy.
Fees for Ireland: €895 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Which Irish bodies oversee energy and network engineering recognition?
The Commission for Regulation of Utilities regulates electricity and gas markets in Ireland, and EirGrid and ESB Networks operate the transmission and distribution systems. Engineers Ireland sets professional engineering standards and chartership. SEIUM's qualifications are private and not accredited by any national body, so their recognition is for employers or the relevant body to determine.
Do Irish energy and utility employers consider private online engineering qualifications?
Irish utilities, grid operators and consultancies generally prioritise professional registration, relevant degrees and operational experience. A private online qualification may support your application as evidence of study, but how it is weighed is at each employer's discretion. We cannot guarantee any outcome, so ask prospective employers directly.
Can I study alongside a job, and does my employer need to fund it?
The programme is online and taught in English, so you can study from home in Ireland with no travel and no student visa required. Plan for 1,900 hours on a master's, 800 on a postgraduate diploma or 300 on a specialist course. Each student has an assigned technical tutor, fees can be paid in instalments, and employer funding is possible but not required, so it is worth raising with your employer.

How you'll learn
The programme is delivered 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is PSCAD, DIgSILENT PowerFactory, EMTP and MATLAB, in free, academic or evaluation versions. Practical work is based on real procedures: harmonic impedance sweeps, emission allocation studies and verification measurements in substations. Assessment is continuous by module, plus the final project.
Standards covered: IEC TR 61000-3-6; IEC 61000-4-7; IEEE 519-2022; IEC 60871-1; IEC 60076-6; IEC 61000-4-30.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
