Indian Queens Power Station (IQPS) is an Open Cycle Gas Turbine (OCGT) power station located in Cornwall. The station has an output capacity of 140 MW providing voltage support to the UK electricity market.


To combat energy short fall this winter, IQPS wanted to offer an increased energy generation to National Grid. An air quality assessment was required to understand the impacts from the increase in the number of operational hours to support the application for variation to the Environmental Permit.


MGL completed air dispersion modelling to predict the ground level concentrations at the maximum point of impingement, human receptors, and ecological receptors. Additionally, nitrogen and acid depositions were calculated for ecological sites.

The air dispersion modelling was completed using ADMS-Extra software and 5-years of meteorological data with relevant buildings and terrain datasets in accordance with the Environmental Agency guidance.

Action and outcome

An air dispersion modelling report and modelling files were produced for submission to EA. The technical report assessed the significance of the modelling results in accordance with the Environmental Agency and Department for Environment, Food and Rural Affairs (DEFRA) guidelines.

With our in-house systems like automated spreadsheets and templates, we are able to provide our client with a cost-effective, quality report efficiently within budget.
