Oman peak shaving

Located on the southeast coast of the Arab Peninsula, the Sultanate of Oman has nominal rainfall and temperatures exceeding 50°C (122°F) during the summer. The hottest months are typically from May to September, when heavy demand on the country''s power grid can cause intermittent power outages, leading to disruptive economic and social conditions. The Oman Power and Water Procurement Company contracted for seasonal back-up power solutions to support the national grid during the peak demand period.

APR Energy designed, installed and commissioned a fast-track, turnkey power plant to provide 24MW of peak-demand backup power via MEDCO, one of the Sultanate''s electricity distribution companies. Using our proprietary modular system of connecting generators and transformers, we were able to deploy and commission the site in less than 20 days from arrival of the equipment to the site. Local specialized contractors were used to fabricate the fuel supply system and build the interconnection infrastructure.

As a standby supplement to the existing power grid, our turnkey diesel power solution provided three months of reliable backup capacity during the peak demand season. Using our proprietary modular system, we were able to fully dismantle and vacate the site in only eight days upon completion of the contract.

With the economy in Malaysia growing at 7.7 per cent and demand for electricity growing at the same rate, Malaysia Sabah Electricity Sdn Bhd (SESB) realised they were going to have to ramp up their energy output.

They had plans to build a 300 MW independent power plant, but knew they were going to have outages, particularly during peak demand, before the new plant could hang its ''Open for Business'' sign. They needed to manage power consumption during peak hours, and they needed to do it straight away.

We were chosen because we had the shortest lead time of any supplier. Our rapid response time, along with our extensive experience in rental installations and short-term power packages, convinced SESB we were the best people for the job.

We built a 15 MW 20 kV power package with generator transformers, bulk fuel tanks, and a control room in just three weeks. The package was operated by our technicians at full capacity for 12 hours a day during the peak time, and in standby mode for the other 12.

It was a win-win situation: SESB reduced their operating costs as they no longer had to supply peak amounts of power during high-load working hours. Local users could save on electricity bills by managing their consumption and shifting their electricity demands to cheaper, off-peak periods.

The predicted outages were avoided allowing local businesses to go about their daily activities and the economy to continue its growth path. Our package also allowed SESB to concentrate on long term plans, while we managed power consumption on their behalf.

One of the biggest expenses utilities face is their monthly power demand. SurvalentONE Dynamic Voltage Regulation (DVR) can help you reduce peak demand, prevent brownouts, conserve energy, achieve cost-savings, keep voltages within an optimal range, and maintain overall system power quality. SurvalentONE DVR takes the guesswork out of lowering peak demand because it continuously monitors field devices, sensors, and AMI meters, thus ensuring that the right balance is struck between demand reduction and end-of-line voltages.
