Natural gas is stored at the TAQA-operated Peak Gas Installation (PGI), and delivered to the Dutch national grid (GTS) to meet peak demand.
PGI uses the Alkmaar gas reservoir located in the centre of the Bergen Concession near the city of Alkmaar and is situated approximately 2,200 metres underground. The installation has a contractual peak capacity of 36 million cubic metres per day and a working gas inventory of 500 million cubic metres.
TAQA holds a 36 percent stake in Peak Gas Installation and is the operator of the storage facility.
The other partners include the Dutch state-owned energy company, EBN (40 per cent), DANA Petroleum Netherlands BV (12 per cent) and Dyas BV (12 per cent). These parties have the right to exploit hydrocarbon resources within the boundaries of the Alkmaar Storage License.
