Lazard Ltd. puts out their annual Levelized Cost of Energy (LCOE) Analysis in Q4 every year, and I always greet it as a worthy piece of market research. Others, however, shower it with critique – some dubious, some accurate. (2014 post on this research here) While there are significant variables that affect the effort to quantify LCOE in one metric, this annual research is quite accurate and appropriately footnoted regarding these variables.
LCOE is defined as all the expense line items of a PV system’s installed cost + the total lifetime cost of the PV system divided by the total amount of energy output in kW hours that the system will put out over its lifetime. (A simple LCOE calculator here).
The latest Lazard research reveals what others including Deutche Bank, UBS, NREL and other analysts have been saying over the past year: utility-scale solar and wind power are increasingly cost-competitive on the wholesale level with traditional energy sources such as coal and nuclear, even in the absence of subsidies. At the retail level cost comparison, its widely competitive unsubsidized with highly subsidized traditional fossil fuel generated power.
The research also shows the all-important progress of energy storage cost reduction and the large benefits of coupling storage with PV to reduce the demand charges and/or provide instant grid frequency stabilization. (A great list of all the energy storage benefits can be found here.)
As a long-term participant in the utility and solar energy industries, it’s breathtaking to see the progress of the PV industry and its market penetration in the last 3 years. The industry has continually had to compete with highly subsidized fossil fuel generation while consistently improving LCOE through hardware, process and regulatory efforts to name a few. Significantly, all of this market penetration progress was achieved with 10X less in government subsidies than traditional fossil fuel-based industries. And with current cost reduction roadmaps throughout the supply chain showing continual lowering of cost’s, the future looks bright.Share this:
