Over the past year, Senior Consultant Lena Hansen has led a series of research projects to rethink the implications of wind and solar’s variability. In the process, she and her colleagues are re-evaluating the economics of putting more renewable energy on the grid.
The key, according to Hansen, is for utility managers to think of all their wind and solar installations as a portfolio.
“No person would invest in just one stock,” says Hansen. In the financial markets, most people forego the huge risks and potentially large gains of owning shares of one company for the reduced risk and smaller rates of return of owning shares in multiple companies, she explains.
Hansen argues that the same should go for utilities investing in wind and solar.
