==Economics of energy trading==
 
VFTs provide the technical feasibility to flow power in both directions between two grids, permitting [[electricity exchange|power exchanges]] that were previously impossible. Energy in a grid with lower costs can be transmitted to a grid with higher costs (higher demand), with energy trading. Power capacity is sold by providers. Transmission scheduling rights (TSRs) are auctioned by the the transmission line owners.
 
Financial Transmission Rights (FTRs) are a financial instrument used to balance energy congestion and demand costs.
