Where the article explains it

A firm can reach a target power capacity $P^*$ either by waiting for grid interconnection, taking time $T_{\text{grid}}$ , or by generating on site in the shorter time $T_{\text{site}}$ , at an extra cost $\Delta$ C over grid power — fuel, turbine leasing, and the practical cost of operating ahead of a permit, including the risk of enforcement.

The passage around this formula

Model the choice as a simple trade. A firm can reach a target power capacity $P^*$ either by waiting for grid interconnection, taking time $T_{\text{grid}}$ , or by generating on site in the shorter time $T_{\text{site}}$ , at an extra cost $\Delta$ C over grid power — fuel, turbine leasing, and the practical cost of operating ahead of a permit, including the risk of enforcement. Let s be the value the firm places on each unit of time saved reaching $P^*$ sooner. A firm behaves as though it believes
