The Government of Tonga has formulated targets to transform its energy sector by achieving a 50 percent share of renewables in the country’s energy generation mix by 2020 and 70 percent by 2030. However, achieving these targets require catalytic investments to transform the country’s energy infrastructure.

Tonga has proven through the past decade of TERM implementation that it is serious about creating this future energy system. Some of Tonga’s impressive accomplishments from period include On track to reach renewable electricity of 50%.
From 2010-2020, the Tonga Energy Road Map TERM policies provided a least -cost approach and implementation plan to reduce Tonga’s vulnerability to oil price shocks and achieve an increase in quality access to modern energy services in a financially and environmentally sustainable manner.
Each of the mitigation opportunities in Tonga’s project pipelines have different funding potential. Some projects are likely to be commercially viable – that is, they can be funded by users. Users may either be willing to pay more due to better service or fund the project because it delivers cost savings to them.
The global commercial and industrial solar energy storage battery market is experiencing unprecedented growth, with demand increasing by over 400% in the past three years. Large-scale battery storage solutions now account for approximately 45% of all new commercial solar installations worldwide. North America leads with a 42% market share, driven by corporate sustainability goals and federal investment tax credits that reduce total system costs by 30-35%. Europe follows with a 35% market share, where standardized industrial storage designs have cut installation timelines by 60% compared to custom solutions. Asia-Pacific represents the fastest-growing region at a 50% CAGR, with manufacturing innovations reducing system prices by 20% annually. Emerging markets are adopting commercial storage for peak shaving and energy cost reduction, with typical payback periods of 3-6 years. Modern industrial installations now feature integrated systems with 50kWh to multi-megawatt capacity at costs below $500/kWh for complete energy solutions.
Technological advancements are dramatically improving solar energy storage battery performance while reducing costs for commercial applications. Next-generation battery management systems maintain optimal performance with 50% less energy loss, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $1,000/kW to $550/kW since 2022. Smart integration features now allow industrial systems to operate as virtual power plants, increasing business savings by 40% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 30% for commercial storage installations. New modular designs enable capacity expansion through simple battery additions at just $450/kWh for incremental storage. These innovations have significantly improved ROI, with commercial projects typically achieving payback in 4-7 years depending on local electricity rates and incentive programs. Recent pricing trends show standard industrial systems (50-100kWh) starting at $25,000 and premium systems (200-500kWh) from $100,000, with flexible financing options available for businesses.
