Power for wild places


Power for wild places

Everyone should have access to cheap, clean, reliable power. We work with government agencies, local businesses, traditional land owners, and local communities to build a more sustainable future for islands and remote areas.


What We Do

What We Do


We specialise in remote island power - the design and development of renewable energy systems for island communities.
Our focus is on offgrid and remote island communities that use diesel generators for power generation.

Construction & Deployment
of Hybrid Microgrids

We build and install hybrid renewable energy projects using solar, wind, battery storage, and advanced control systems.

We believe all systems should be scalable and modular, and support the growth of future projects in remote areas.

We can provide staged integrations of high-penetration renewables into existing diesel networks, and automatic switching between renewables, storage or existing diesel genset assets.

Operation & Maintenance
of Renewable Infrastructure

We can provide operation and maintenance capabilities for renewable energy projects, microgrids, and other power infrastructure.

Services include complete operational control of the network, day-to-day power service and plant operation, and power services for critical assets.

We can provide regular maintenance and inspection capabilities and can respond to unscheduled maintenance and network faults on-site or remotely.

Island, Remote Area &
Offgrid Location Logistics

We are used to dealing with island shipping and remote area logistics, and we can train or work with local labor teams for local economic development.

We have practical experience dealing with projects in highly corrosive island and marine environments, as well as projects in tropical cyclone areas including Australian wind regions B & C.

Support services include remote monitoring, on island support, and technicians who can fly out for critical service issues.



Our services include feasibility and design studies, financial modelling, strategic planning, and project management. 

System Modelling & Engineering Design

System design, scoping, and evaluation of multiple design topologies across a range of renewable energy sources and storage options. 

We use software modelling to simulate multiple system designs so that each system achieves the highest efficiency and value for money.

Financial Modelling & Business Case Optimisation

We use custom financial modelling to understand and maximise the commercial viability of each project.

We model all commercial considerations, available energy resources, and a range of engineering solutions to determine the best system configuration for each site.

Business model evaluation and power purchase agreement structuring and negotiation can be used to provide the commercial basis for feasibility studies, debt finance, or project funding.

Project Management, Planning & Approvals

We can also provide project management capabilities, from early stage concepts through to large scale projects.

Our services include the development of complete power delivery and operation plans, regulatory & HSSE compliance, tender submissions, approvals, and risk management.

We like working on complex projects with partnerships that run across local communities, governments, and private company stakeholders.


About ISLAND Power CO

About ISLAND Power CO


We build island microgrids for remote communities so they can save money, reduce carbon emissions, and improve power service reliability. Our goal is 100% renewable energy for multiple islands and remote communities in the Indian Ocean Territories by 2025.

We design, develop, and deploy hybrid renewable energy microgrids for remote communities and islands that have high-cost, high-carbon power infrastructure. Our ideal projects range from 50 kW village installations to low MW utility scale systems in offgrid communities. Our focus is on remote islands and isolated communities with difficult logistics, heavy reliance on diesel fuel, and a high levelised cost of electricity. We develop projects in-house and also work with large EPC partners to deliver utility scale projects efficiently and cheaply.



Our team has seven years of experience delivering power generation at the megawatt scale for island and remote communities, including the management, operation, and oversight of three Government owned power stations in the Indian Ocean Territories in Australia.

We have experience ranging from the design and modelling of tiny standalone ecoresort microgrids (50 kW) to the management, operation, and technical support of megawatt-scale government-owned island power stations (1-8 MW). For small resort-scale developments we provide packaged design, engineering, and installation, while for megawatt-scale projects our preferred model is to develop microgrids as an independent power producer, selling electricity under a power purchase agreement. We work primarily in offshore remote communities in Australia and Indonesia. We can help you with the following:

Photovoltaic Solar

Battery Storage



Control Systems

Remote Monitoring

Diesel Integration





As well as our previous power generation and distribution work in the Indian Ocean Territories
our team has completed a range of remote island power projects, including:



Development of detailed software models for the Home Island Power Station, West Island Power Station, and Christmas Island Power Station including model representations and simulations of all diesel power assets and station operation.

We developed technical models to represent installed diesel assets at each station, including multiple diesel gensets and configurations, N+1 operating rules, spinning reserve, and load following and load sharing behaviour.

These models are accurate software models of the power stations in the Indian Ocean Territories and are used to simulate and forecast diesel operation and renewables integration into the local power network at each island.

Design and modelling of megawatt-scale hybrid renewable system topologies for West Island, Home Island, and Christmas Island, including photovoltaic solar, battery storage, wind turbines, advanced control systems, and diesel asset integration.

We used HOMER, PVSyst, Helioscope, Meteonorm, and our own custom software models to develop system topologies based on least cost optimisation for solar, storage, gensets, and control systems at each island, across a range of economic sensitivity analyses.

Design models include calculation of the levelised cost of electricity at each station, with simulations optimised for lowest capital cost, LCOE, and NPV. Designs target spinning reserve requirements, low genset runtimes, carbon emission reductions, diesel fuel savings, and O&M cost savings.


Design and engineering for solar and battery storage systems including 50 kW, 150 kW, 200 kW, 550 kW, 1.3 MW, and 6 MW systems at Cocos and Christmas Island. Designs support smoothing, grid protection, export control, diesel integration, advanced control, and remote access & monitoring.

We have installed and commissioned solar, battery, and diesel genset systems in the IOT and Indonesia, with projects up to
550 kW / 660 kWh in current development including grid connected, standalone power, and hybrid renewable systems in offgrid and weak-grid areas.

Other work includes design for mining, immigration, environment, airports, and ecotourism facilities in the IOT, and 700 kVA diesel genset commissioning for emergency backup power supply.


Development of project finance yield and financial models for utility-scale renewable energy systems at Home Island, West Island, and Christmas Island. We developed financial models for each island including construction, operation, and delay periods; system performance estimates; senior debt sources, committed and contingent equity; sculpted and annuity debt models; debt service reserve and maintenance reserve accounts, and p50, p90, and p99 exceedance probability yield estimates.

Models include 25 year project lifetime financial statements (cash flow, profit & loss, balance sheets); operating cashflows, cash flow available for debt service (CFADS); LCOE and PPA pricing; tax and depreciation, geared & ungeared analyses, pre-tax & post-tax analyses; scenario and sensitivity analyses; and project and equity returns & metrics (NPV, IRR, LLCR, PLCR, DSCR, EBIDTA, NPAT).


Development of feasibility studies, detailed business case analyses, and due diligence and assessment of major partners for large scale solar project in the remote communities.

We developed a series of detailed business cases, energy roadmaps, and risk management plans for a range of scenarios in the IOT. Our work includes analysis of IPP, PPA, and O&M models; community solar and shared storage; distributed energy resource models including community solar and virtual power plants; utility-side energy storage.

We also run an ongoing process to assess major partners for large scale renewable projects in remote communities. This process includes detailed assessment and due diligence on each firm’s experience, capability, capacity, and proposed solutions to deliver the greatest value for money to the all stakeholders.


Installation and commissioning of advanced power station control systems including programmable Logic Controller (PLC), Human Machine Interface (HMI), engine governing, Supervisory Control and Data Acquisition (SCADA) systems.

Installed and commissioned advanced control systems at the Home Island Power Station including PLC / HMI / SCADA for automated genset switching, load sharing, and load following as well as diesel governor and control system upgrades at the Christmas Island Power Station.

We provide ongoing remote access and monitoring of grid-connected and offgrid renewable systems at Cocos and Christmas over satellite NBN, and developed custom software (RESTful JSON API calls) for remote monitoring and fault alarms for a offgrid solar, battery and inverter system over satellite NBN at Christmas Island.
