Minimum Share of Production

The 'Minimum Share of Production' variable ensures a specific process supplies at least a defined percentage of a fuel's total annual production, regardless of cost-effectiveness, to model policy targets or contractual obligations.

• The Minimum Share of Production variable is used in energy-system-optimization to mandate a minimum contribution from a specific technology or supply source, overriding least-cost dispatch if a cheaper alternative is available. It is typically used to model domestic-supply targets, renewable energy targets, must-run obligations, or take-or-pay contracts.
• The variable is expressed as a percentage from 0 to 100, with a default value of 0. It can be configured as a static value, a conditional value based on the year, or a linear interpolation between two dates.
• There are three primary technical constraints when using this variable: it is only visible in partial and energy-system-optimization scenarios; it cannot exceed the 'Maximum Share of Production' for the same process and year; and the sum of all minimum shares for a single fuel cannot exceed 100%.
