Scenario Fair Shares

Scenario efforts must be allocated to the portfolio’s production profile. To do this, two principles are currently implemented:

  1. Technology Fair Share:

\[p_{i}^{tfsr}(t) = p_{i}(t_0) * \dfrac{s_i(t)}{s_i(t_0)}\]

where:

  • \(s_i(t)\) is the scenario production for technology \(i\) at time \(t\),
  • \(p_{i}(t_0)\) is the production allocated to the portfolio for some technology, \(i\) at time \(t_0\), and
  • \(p_{i}^{tfsr}(t)\) is the portfolio-specific target production for that technology.

We define the “Technology Fair Share Ratio” as:

\[\dfrac{s_i(t)}{s_i(t_0)}\]

  1. Market Fair Share:

\[p_{i}^{mfsp}(t) = p_{i}(t_0) +P(t_0) * \left( \dfrac{s_i(t)-s_i(t_0)}{S(t_0)}\right)\] where:

  • \(P_i(t_0)\) is the portfolio’s total production in the sector at \(t_0\), and
  • \(S(t_0)\) is the scenario total production at \(t_0\).

We define the “Market Fair Share Percentage” as:

\[\dfrac{s_i(t)-s_i(t_0)}{S(t_0)}\]

Calculation
