High voltage direct current power transmission: the economics?

This model captures the economics of transporting electricity (especially from renewable sources, such as wind and solar), over vast distances, using high voltage direct current power cables (HVDC).

Our numbers are based on technical papers, a dozen past projects and a granular bottom-up breakdown of costs (both capex and opex). Our notes from technical papers follow in the final tab as context.

Our base case estimate is that a 10c/kWh transportation spread is required to earn a 10% levered IRR on 1,000-mile cable. Please download the data-file to stress test power costs, power prices,  capex, opex, line losses, leverage levels and fiscal impacts.

The second download compares the cost of transporting large quantities of power down a DC cable, versus converting it into hydrogen and piping the hydrogen.
