5. Key Preesall Credentials
Preesall Underground Gas Storage Scheme
Key Preesall Credentials
Preesall Gas Storage Operation:
12 day injection / withdrawal cycle;
Capable of cycling 28 times a year;
Cycling volume potential of 7.8 bcm per year;
Variable cycling cost of 0.31 p/therm; and
Preesall’s Competitive Advantage:
Faster cycling speed;
Lower cycling costs;
Virtual cavern design – Preesall can cycle at a higher rate & be worked harder over short time periods (e.g., 6 to 12 hour periods within day); and
Significant site development opportunities - a Phase 2 could add caverns doubling WGV and enhancing IRR, utilizing Phase 1 above ground infrastructure.
