The Institution of Power Engineers (formerly IDGTE) is delighted to have successfully issued the 2020 Operational Report. On behalf of the working group we are now pleased to invite you to submit a return for the 2021 Operational Report.

All past contributors and new contributors are invited to send in returns for reciprocating engines, gas turbines, combined cycle power plants, renewable energy and energy storage facilities for any twelve month period during 2019-2021.

The IPowerE Operational Report provides analysis, guidance and benchmark performance indices to users of reciprocating engines, gas turbine plant and combined cycle power plants worldwide as well as all forms of power generation.  The report which was formerly known as the Working Cost Report, has existed over 97 years and relies upon the contributions of Users to ensure it is both comprehensive and statistically valid.  We hope that you will be interested in continuing this work with us and will submit a return for the IPowerE 2021 Operational Report helping to make this a great success.

The Annual Operational Report is a unique compilation of data of value to organisations worldwide, including owners, operators, financial bodies, manufacturers and consulting engineers.  The Report is one of a number of technical papers presented and published by IDGTE annually.  Over recent years we have had 40 countries and territories represented in our reports representing over 600 sites and 3000 prime movers. Please help us to achieve our target by sending in your return and recommending to others.

All contributors to the report will receive a copy of the full results as soon as they have been compiled and a printed copy of the report when it is issued. Contributors will also receive an invitation to join the Ops Report discussion meeting as soon as this can be arranged.

Please download the guidance notes and forms. Returns may be sent in at any time.  We request that these are sent in by 30 September 2021 however just let us know if you need more time.

If you have any query or would like assistance, or more time to submit, then please contact the IPowerE office in Bedford, United Kingdom and we will be delighted to help.
