Supportive Government Policies
Worldwide incentives such as subsidies, tax credits, and renewable portfolio standards are spurring investment. For example, Canada’s Investment Tax Credit (ITC) offers a 26% credit for renewable installations (2020–2022) and 22% in 2023, promoting solar, wind, and tidal projects.
Energy Affordability and Security
With the global energy crisis escalating, utility-scale solar and wind solutions are seen as both cost-effective and secure. Grid resilience and power system integration are central to ongoing investments.
Rise in Utility-Scale Projects
Projects over 10 MW in capacity—particularly solar PV and offshore wind—are gaining favor due to favorable state-level policies and local incentives. Tax breaks and clean energy targets continue to shape project development strategies.
Advanced Technology Integration
The role of generative AI, biofuels, and hydrogen is expanding. Integration of smart grids, distributed systems, and energy storage is a notable trend, especially for addressing intermittency in power generation.
