Enabling islands to be more sustainable

Ricardo has strong expertise in supporting many island communities across the world, working on projects including the Pacific islands, Caribbean islands, Bermuda and many British Overseas Territories, supporting initiatives to reduce carbon emissions, integrate more renewables into island energy systems from strategy planning all the way through to implementation.

Ricardo supports sustainable development in island states through providing consulting services in the following areas:

• Energy policy and cross-sector strategy 
• Developing enabling regulatory environments
• Integrated resource planning and clean power planning - learn more about power planning here
• Feasibility studies and procurement support
• Licensing, standards and processes for renewable energy - learn more about Ricardo's renewable energy plans here
• Support for island power grid stability and resilience - to read our series of reports on our hydrogen demand mapping reports to help accelerate sustainable transport and decarbonise distilleries
• Smart networks, energy storage and demand-side management - learn more about our energy storage 
• Energy strategy, planning and implementation for airports and ports
• Developing local energy solutions for commercial and industrial sites
• Waste to energy across multiple feedstocks
• Models for regional harmonisation and cooperation
• Capacity strengthening and skills development
• Development and implementation of Nationally Determined Contributions and long-term low emission strategies
• Combined energy and economic assessment tool for the energy transition in islands calculating energy demand and supply, power generation mix, investment expenditure.

Project highlights

Bermuda Integrated Resource Plan

Ricardo’s energy experts supported the Regulatory Authority of Bermuda to develop the Integrated Resource Plan. Ricardo used in- house system planning tools tailored to island systems and coordinated network studies. We demonstrated the least-cost scenario involves significant renewable energy penetration over the next decade. In the new IRP, 85% of energy would come from renewable sources by 2035 and more than 3 million tons of carbon emissions would be avoided.

This enabled the Regulatory Authority to select the energy mix that would best meet Bermuda’s ambitious and consumer and climate-focused needs over the next 20 years.
