Further Phase-2 of the project will be executed if there is an additional gas demand from M/S KPCL Yelhanka power plant.

Risk Assessment study for NATURAL GAS PIPELINE TO POWERPLANT included the following steps.

  • Identification of Hazards (Fire / Explosion uncontrolled release of Hazardous material / Flash Fire / Jet Fire / Over Pressure Explosion etc.)
  • Identification of Maximum Credible Accident (MCA) scenario.
  • Frequency Analysis using internationally accepted database and Evaluation of the -likelihood of occurrence of possible events.
  • Consequence modelling and analysis for the identified hazard covering impact on people and potential escalation
  • Estimation of Individual Risk(IR) and Societal Risk (SR)
  • Recommendations
