In the ever-changing natural gas business, it seemed that gas storage usage remained the same year after year. The only change was the amount stored for seasonal swings in natural gas and electric generation usage.
That was then. Pipelines and local distribution companies (LDCs) used natural gas storage as a tool to balance these seasonal swings and to mitigate natural gas supply shortages during peak periods. Typically, storage was tied to only one pipeline, and bundled with the pipeline’s other services, limiting a storage customer’s flexibility to take full advantage of the storage capability.
This is now. “Winter/summer peaking” and “shoulder month injection” seasons are replacing traditional “summer injection” and “winter withdrawal” seasons. More natural gas storage is being developed by independent companies. Driving the change are unbundled pipeline gas services and demand from independent power producers (IPPs) to provide load following services for electric generation.
In short, storage is being designed and used in completely different ways today.
