The falling cost of solar and wind power installation across major markets should ensure sustained renewables growth in all major markets, with much less reliance on government incentives, according to the latest report 10 Years in Power and Renewables by Fitch Ratings.
Global power generation from renewable sources has almost quadrupled in the last 10 years, while global installed renewable capacity had grown by over 6x to 770GW by the end of 2016.
This growth would not have happened without government subsidies and other incentives, which have helped create an active industry, albeit with many regional differences.
But renewables are now starting to achieve grid price parity, pricing out traditional power and making incentives in some countries and regions redundant, according to Fitch Ratings. This suggests that renewables growth is becoming self-sustaining and that the US plan to withdraw from the Paris climate accord will not affect sector growth.
The rating agency has identified other major trends affecting the sector in the next 10 years, which include advancements in storage technologies that will support renewables, the growth of self-generation and local distribution systems, and the divergence of demand trends between developing and developed markets.
Improvements in battery storage technology could have a bigger impact on the rate of growth over the next decade and beyond by alleviating the inherent intermittency problems of renewables.
Better storage options could also reshape the distribution models of utility companies, for example through further deployment of rooftop solar panels. In some locations, this could culminate in a move towards local distributed systems, or “mini-grids”.
Self-generation could facilitate the shutdown of some traditional power sources and further decentralize energy distribution. However, self-generation is unlikely to be universally achievable; it is unlikely to work in heavily urbanized areas. According to Fitch Ratings, there is a need for at least some centralized generation and transmission systems will prevail.
Globally, demand trends are likely to follow two distinct paths over the next decade. Overall power demand in developing markets will continue to rise as these countries catch up with the per-capita energy use of developed markets. But we expect the trend in developed markets to be flat or potentially to increase slightly, depending on the level of take-up of electric vehicles in these markets.
The most disruptive changes are likely to come through advances in technology, and the speed at which changes occur may be much faster than anticipated. Game-changing events such as those caused by geopolitical factors or significant climate change events could also affect the industry.
