International classification and verification company RINA Services has performed the design approval for the world's largest Compressed Natural Gas storage plant in Grati, Indonesia. The CNG will feed the local 300 MW power plant.

The plant, operated by Indonesia’s PT PLN (Persero), burns up to 15 million standard cubic feet per day (mmscfd) of gas from the CNG storage, driving three gas turbines. Adding a CNG plant to the existing power station tackles the issue of peak load demand. The CNG storage takes in pipeline gas when the plant is not at full capacity. At peak load, the stored gas reserves boost the plant.

Angelo Lo Nigro, General Manager Energy Solutions, RINA Services, says, “RINA is a world leader in CNG technology approval. It is one of the only classification societies with direct experience of the use of CNG in the maritime field and has developed special rules for its future use. That expertise and experience is valued in the power generation field.”
