How much is the price of outdoor power supply BESS in Papua New Guinea

Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it's useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here's a simple breakdown:

It is nonetheless still eye-opening to note just how big those differences in cost are. The average for a turnkey system in China including 1-hour, 2-hour and 4-hour duration BESS was just US$101/kWh. In the US, the average was US$236/kWh and in Europe US$275/kWh, more than double China's average cost.

Most BESS products on the market require an external power supply circuit for their auxiliary loads, although some have built-in circuits and do not need an external supply.

The vision for reforming Papua New Guinea's power sector is becoming clearer, with power auctions likely to play a major role in driving down electricity prices and helping the country meet its future electricity needs.

The cost of the auxiliary power supply circuit and any required backup power sources must be accounted for in the project's capital expenditures. Project owners are also responsible for the electricity costs associated with the BESS auxiliary load during operation.

Several factors can influence the cost of a BESS, including: Larger systems cost more, but they often provide better value per kWh due to economies of scale. For instance, utility-scale projects benefit from bulk purchasing and reduced per-unit costs compared to residential installations. Costs can vary depending on where the system is installed.
