2019–2023: The RDEG market was characterized by foundational infrastructure investment, with solar PV emerging as the dominant force. The world saw China alone adding 65 GW of solar capacity in 2022, part of a global pivot toward renewable decentralization driven by urbanization, rising power demands, and climate goals.
2024–2028 Outlook: The coming years will see RDEG technologies mature from an alternative model to a primary energy solution. Driven by the high costs of grid expansion, vulnerability to cyber-attacks, and a global electricity demand rise of 2.2% in 2023, RDEG technologies are entering a strategic scaling phase.
With the global RDEG market increasingly addressing intermittency and security concerns through microgrids, fuel cells, and combined heat and power (CHP) systems, the path forward is clear: energy production where it’s consumed.
Legacy Disruption: Solar PV faced challenges from intermittency and panel inefficiencies, often requiring costly backup solutions.
Emerging Strategy: Adoption of on-grid and off-grid solar systems enables energy flexibility, while CHP integration and energy management systems improve reliability.
Analyst Insight: Solar PV, which held a major market share in 2023, is expected to continue leading the RDEG expansion due to decreasing costs and rising global capacity.
Business Case: In the US, the rise in residential solar installations reflects shifting energy consumption models. Major utility players now offer solar-inclusive home energy packages—turning consumers into producers.

Legacy Disruption: Previously underutilized due to high cost and low awareness, these technologies were niche components of distributed systems.
Emerging Strategy: Their low emissions and chemical-to-electricity efficiency make them ideal for clean decentralized generation, especially in industrial and off-grid sectors.
Analyst Insight: Fuel cells, producing only water as a byproduct, are gaining traction for their environmental benefits and potential for seamless microgrid integration.
Business Case: Capstone, a leader in microturbine solutions, expanded its industrial offerings in 2023, powering remote mining operations in Southeast Asia—reducing diesel dependence and emissions.
Legacy Disruption: Centralized wind projects struggled to provide reliable, consistent output, especially during low-wind periods.
Emerging Strategy: Localized wind installations and hybrid RDEG systems (combining wind and gas turbines) are being deployed to overcome intermittency.
Analyst Insight: Gas turbines and reciprocating engines, once seen as transitional technologies, are now viewed as complementary assets in hybrid renewable systems.
Business Case: In rural India, hybrid wind-gas turbine systems now provide power to previously off-grid villages, supported by public-private partnerships and sustainability grants.
