CfDs allow a fixed price to be paid for a product for a particular duration. Any deviation from the market price from this fixed price is paid for by the CfD broker, which in this case is likely to be a government or consumer. We assumed the duration of the CfD was for the whole project. A RAB allows a project developer to start receiving payment for their product during the project's construction phase before operation begins. This is done through an agreement between the project developer and a regulatory body. In addition, the price charged during operation is also set by the regulator rather than an open market. Finally, a state-owned DAC facility or a DAC facility backed by state loans could take advantage of the low-interest rates available to a government through their high-risk tolerance.
