The SCM assumes optimal economic behavior for all farms: if the costs of biogas recovery are not met by the price offered, the farms will not produce electricity in our simulated market. However, there may be real-world situations where farms face competing incentives and are willing to accept less than the market value for their bioenergy. For example, the amount of manure that can be applied to crop fields is regulated in some regions , so farms may choose to produce bioenergy at a loss to avoid more extreme penalties.
