Asia-Pacific
Microgrid and energy software for Asia-Pacific projects
Spanning developed economies, emerging markets, and Pacific island utilities. From grid-scale BESS in Japan and Australia to rural electrification across South and Southeast Asia, HOMER models the full spectrum of Asia-Pacific energy challenges.
Asia-Pacific's three energy realities
Asia-Pacific is not one market. Treating Japan, Indonesia, and Fiji as a single category produces content that speaks to none of them. HOMER serves three distinct sub-segments across the region, each with different project types, regulatory contexts, and modelling requirements.
Acknowledging this complexity is itself a competitive advantage. HOMER's architecture — location-specific climate data, configurable tariff structures, and dispatch strategies that work equally for grid-tied and off-grid systems — means the same software genuinely serves all three. The challenge is knowing which configuration applies where.
Developed APAC: Japan, Korea, Australia, New Zealand, Singapore, Taiwan
Grid-scale BESS is expanding rapidly in Australia's National Electricity Market (NEM) and Japan's JEPX market, both of which have sophisticated spot pricing that HOMER Front models natively. Corporate RE100 commitments and industrial decarbonisation under SBTi are driving C&I storage in South Korea, Taiwan, and Singapore. AI data centre grid constraints in Sydney, Melbourne, and Singapore are creating new behind-the-meter design requirements.
Australia's remote area power supply (RAPS) sector — WA's isolated network, outback Queensland, the Pilbara — represents a mature off-grid market where HOMER has established references. Japan's 離島 (remote island) programme manages 100+ isolated grid systems. New Zealand's distributed generation rules and New South Wales' long-duration storage roadmap create new modelling needs in both markets.
Emerging APAC: India, Indonesia, Philippines, Vietnam, Thailand, Malaysia, Bangladesh, Sri Lanka
India's renewable auction market — among the world's most competitive — has produced solar tariffs below $0.02/kWh. SECI, NTPC, and state DISCOMS are procuring storage at scale, making HOMER Front increasingly relevant for Indian IPPs and EPCs. Indonesia's 35 GW power programme and its island grid challenges make it one of the region's most complex modelling environments. The Philippines' energy mix — coal-heavy but with acute island power cost problems — is transitioning through the DOE's Green Energy Auction Programme (GEAP).
Industrial microgrids in Vietnam's special economic zones, Thailand's large C&I sector under the Alternative Energy Development Plan (AEDP), and floating solar across South and Southeast Asia's reservoirs and fish farms are emerging design categories that HOMER handles with established component models.
Pacific islands: Fiji, Samoa, Tonga, Vanuatu, Cook Islands, Marshall Islands, Palau, FSM, Kiribati, Tuvalu, PNG
HOMER originated at the US National Renewable Energy Laboratory as a tool for village power — the Pacific islands were among the first deployment contexts. That heritage means the Pacific Power Association has long used HOMER as a standard tool across member utilities. Tonga, Samoa, and Tokelau have achieved or are targeting 100% renewable electricity. The Marshall Islands and Kiribati face existential climate risk that makes energy security a priority of a different kind.
Donor-funded projects from the World Bank, the Asian Development Bank, New Zealand MFAT, Australia's DFAT, and USAID in this region regularly require HOMER models for feasibility and financial close documents. Climate resilience — designing systems that remain operable through cyclones and storm surges — is a design constraint HOMER's simulation framework can accommodate through scenario analysis.

Selected Asia-Pacific projects
NEM ancillary services optimisation
An Australian IPP used HOMER Front to model a 100 MW BESS asset across FCAS (Frequency Control Ancillary Services) markets and NEM spot trading. The analysis identified an optimal dispatch strategy that improved projected IRR by 180 basis points.
ADB-funded village power, Fiji
HOMER Pro was used to size solar-battery village power systems across 18 communities under an Asian Development Bank electrification programme. The models produced the load profile, battery sizing, and generation mix required for ADB financial close documentation.
DISCOM-integrated C&I solar-storage
An Indian EPC used HOMER Grid to model a 5 MW / 10 MWh rooftop-plus-storage system for a pharmaceutical manufacturer under Tamil Nadu's net metering framework. HOMER identified demand charge savings of INR 1.8 crore per year.
