NEW YORK - There is a transformation happening in global energy markets that is worth noting as 2016 comes to an end: Solar power, for the first time, is becoming the cheapest form of new electricity.
There have been isolated projects in the past where this happened: An especially competitive auction in the Middle East, for example, resulting in record-cheap solar costs. But now unsubsidized solar is beginning to out-compete coal and natural gas on a larger scale, and notably, new solar projects in emerging markets are costing less on average than wind projects, according to fresh data from Bloomberg New Energy Finance.
For the first time, solar prices have fallen below wind. While this was bound to happen eventually, given that solar-panel prices are falling faster than more-established wind turbines, few predicted it would happen this soon.
“Solar investment has gone from nothing — literally nothing — like five years ago to quite a lot of money,” said Ethan Zindler, head of U.S. policy analysis at BNEF. “A huge part of this story is China, which has been rapidly deploying solar” and helping other countries finance their own projects.
Half the price of coal
This year has seen a remarkable run for solar power globally. Auctions, where private companies compete for massive contracts to provide electricity, established record after record for cheap solar power. It started with a contract in January to produce electricity for $64 per megawatt-hour in India; then a deal in August pegging $29.10 per megawatt hour in Chile. That is record-cheap electricity — roughly half the price of competing coal power.
“Renewables are robustly entering the era of undercutting” fossil fuel prices, BNEF chairman Michael Liebreich said in a note to clients this week.
Those are new contracts, but there are plenty of projects reaching completion this year, too. When all of the 2016 projects are tallied in coming months, it is likely that the total amount of solar photovoltaics added globally will exceed that of wind for the first time. The latest BNEF projections call for 70 gigawatts of newly installed solar in 2016 compared with 59 gigawatts of wind.
The overall shift to clean energy is more expensive in wealthier nations, where electricity demand is flat or falling and new solar must compete with existing billion-dollar coal and gas plants.
But in countries that are adding new electricity capacity as quickly as possible, “renewable energy will beat any other technology in most of the world without subsidies,” said Liebreich.
The world recently passed a turning point and is adding more capacity for clean energy each year than for coal, natural gas, and oil combined. Peak fossil fuel use for electricity may be reached within the next decade.
Thursday’s BNEF’s report, called Climatescope, ranks and profiles emerging markets for their ability to attract capital for low-carbon energy projects. The top-scoring markets were China, Chile, Brazil, Uruguay, South Africa, and India.
When it comes to renewable energy investment, emerging markets have taken the lead over the 35 member nations of the Organization for Economic Cooperation and Development (OECD), spending $154.1 billion in 2015 compared with $153.7 billion by those wealthier countries, BNEF said.
The growth rates of clean-energy deployment are higher in these emerging market states, so they are likely to remain the clean energy leaders indefinitely, especially now that three quarters have established clean-energy targets.
Still, the buildup of wind and solar takes time and fossil fuels remain the cheapest option for when the wind doesn’t blow and the sun doesn’t shine. Coal and natural gas will continue to play a key role in the alleviation of energy poverty for millions of people in the years to come.
But for populations still relying on expensive kerosene generators, or who have no electricity at all, and for those living in the dangerous smog of thickly populated cities, the shift to renewables and increasingly to solar can’t come soon enough.
Wind is still cheaper in many OECD nations, including the U.S. That is largely an issue of sunshine and wind availability in the respective regions.
