Principles of cost-benefit analysis
Article 39
1
Power-generating facility owners and DSOs including CDSOs shall assist and contribute to the cost-benefit analysis undertaken according to Articles 38 and 63 and provide the necessary data as requested by the relevant system operator or relevant TSO within three months of receiving a request, unless agreed otherwise by the relevant TSO. For the preparation of a cost-benefit-analysis by a power-generating facility owner, or prospective owner, assessing a potential derogation pursuant to Article 62, the relevant TSO and DSO, including CDSO, shall assist and contribute to the cost-benefit analysis and provide the necessary data as requested by the power-generating facility owner, or the prospective owner, within three months of receiving a request, unless agreed otherwise by the power-generating facility owner or the prospective owner.
2
A cost-benefit analysis shall be in line with the following principles:
a
the relevant TSO, relevant system operator, power-generating facility owner or prospective owner shall base its cost-benefit analysis on one or more of the following calculating principles:
1. the net present value;
2. the return on investment;
3. the rate of return;
4. the time needed to break even;
b
the relevant TSO, relevant system operator, power-generating facility owner or prospective owner shall also quantify socioeconomic benefits in terms of improvement in security of supply and shall include at least:
1. the associated reduction in probability of loss of supply over the lifetime of the modification;
2. the probable extent and duration of such loss of supply;
3. the societal cost per hour of such loss of supply;
c
the relevant TSO, relevant system operator, power-generating facility owner or prospective owner shall quantify the benefits to electricity markets, cross-border trade and integration of renewable energies, including at least:
1. the active power frequency response;
2. the balancing reserves;
3. the reactive power provision;
4. congestion management;
5. defence measures;
d
the relevant TSO shall quantify the costs of applying the necessary rules to existing power-generating modules, including at least:
1. the direct costs incurred in implementing a requirement;
2. the costs associated with attributable loss of opportunity;
3. the costs associated with resulting changes in maintenance and operation.
