Low load diesel perceptions and practices within remote area power systems

Abstract

Diesel generators account for the majority of generation into remote and off-grid power systems. However, complementary generation alternatives are increasingly becoming both available and cost competitive, specifically via the introduction of renewable technologies. Achieving optimal integration requires the diesel generators to be able to operate sustainably at low load levels. A key roadblock to greater renewable utilisation remains the inability of diesel infrastructure to run at low loads. The University of Tasmania has surveyed extensively across remote area power system stakeholders to define current perceptions and practices surrounding this issue. The survey finds a market frustrated by a lack of information, supporting large cultural bias to long held operational practices and beliefs. Barriers to implementation of low load specific technologies are thus both technical and cultural in nature. With regard to both, improved access to information would address market disinformation and displace myths currently responsible for inaction within the sector.
