Building new renewables is now cheaper than just running old coal and nuclear plants.

By  In one of the fastest and most astonishing turnarounds in the history of energy, building and running new renewable energy is now cheaper than just running existing coal and nuclear plants in many areas. A widely-used yearly benchmarking study — the Levelized Cost of Energy Analysis (LCOE) from the financial firm Lazard Ltd. — reached this stunning conclusion: In many regions “the full-lifecycle costs of building and operating renewables-based projects have dropped below the operating costs alone of conventional generation technologies such as coal or nuclear.” Lazard focused on the cost of a power for a plant over its entire lifetime in North America, and how the “increasing economic advantage of renewables in the U.S.” will drive even deeper penetration of solar and wind here. But Lazard also makes a key global point: It’s more expensive to operate conventional energy sources in the developing world than it is in the United States. So the advantage renewables have over conventional sources is even larger in the rapidly growing electricity markets like India and China. Since power from new renewables is cheaper than power from existing coal and nuclear, it’s no surprise that the lifetime cost of new renewables is much cheaper than new coal and nuclear power. And that gap is growing. Lazard notes that in North America, the cost for utility scale solar and wind power dropped 6 percent last year, while the price for coal remained flat and the cost of nuclear soared. “The estimated levelized cost of energy for nuclear generation increased ~35 percent versus prior estimates, reflecting increased capital costs at various nuclear facilities currently in development,” the analysis found. Indeed, as Lazard shows in this remarkable chart, while solar and wind have dropped dramatically in price since 2009, nuclear power has simply priced itself out of the market for new power.
