LNG FOR TEMPORARY & REMOTE POWER

Many of the remote power projects we have executed in the USA have been temporary in nature where the customer desires to begin operations ahead of the availability of line power from the regional electricity provider (as is described in the actual case study below). Increasingly however, we are seeing new power project opportunities in very remote areas that will not have line power for the foreseeable future—in places like northern Canada, Mexico and occasionally in some of the more remote Rocky Mountain areas within the USA. In these locations, not only is there an absence of a power grid, but the fuel distribution infrastructure is also undeveloped. Given that natural gas AND small on-site liquefaction LNG plants are relatively more “available” at a smaller scale than crude oil refineries, especially so internationally, we see LNG providing fuel over the long term for these off-grid/off-pipeline projects.

Remote Power Challenge:

The client was in the final stages of completing a large gas processing and compression plant for Bakken basin gas. As the startup date approached, the customer was informed by its local electric utility that the installation of the transmission lines to the facility would be delayed by four to six months. The company’s lost opportunity value was close to $1 million per day in the event of a project delay.
The customer contacted a large, international prime power rental company to provide a 16-MW interim solution. The client initially considered a diesel solution as well as one using purified gas from the gas processing section of the plant. The diesel permit process of the State of North Dakota requires extensive paperwork and public hearings. The gas solution would have required a small design change to the processing plant, but procurement of additional equipment had an unacceptable lead time.

PROMETHEUS ENERGY Solution:

Prometheus Energy was contacted in mid-October and had its solution on site by early December with full commissioning and start of operations beginning before the Holidays.

Prometheus Energy provided approximately 4,800 dekatherms of LNG storage (approximately two days of gas demand) with approximately 140,000 scfh of LNG vaporization using electric vaporizers energized by the on-site prime power solution.

Results:

In addition to meeting the aforementioned aggressive startup schedule, Prometheus Energy continuously operated its LNG system and kept it on stream 99.97% of the time with less than one hour of downtime from December 17th through April 9th of the following year.
