- Identification of variables: a set of risk factors are identified employing techniques as literature review and experts brainstorming (risk variables are listed in Table 1).
- Contextual relationship: It was established between each pair of variables. The self-structural interaction matrix (SSIM) is constructed following the rule: “V” if the risk variable i leads to the variable j (direct relationship); “A” when the variable j leads to the variable i (inverted relationship); “X” if the relationship between risk variables are in both directions (double relationship); and “O” when does not exist relationship between the pair of variables.
- Initial reachability matrix: The SSIM matrix is transformed into a binary matrix (0 and 1’s) following this rule: a) If the variable (i,j) is V, then the variable (i,j) is 1 and the variable (j,i) is 0; b) If the variable (i,j) is A, then the variable (i,j) is 0 and the variable (j,i) is 1; c) If the variable (i,j) is X, then the variable (i,j) and the variable (j,i) takes the value of 1; and d) If the variable (i,j) is O, then the variable (i,j) and the variable (j,i) takes the value of 0.
- Final reachability matrix with transitivity check: It is a verification step of the reachability matrix. This is made by a logical analysis: If a variable A has relationship with another variable B, and, if the variable B has relationship with another C; then, it can be concluded that variables A and C have some relationship.
- Definition of levels: The final matrix is converted into a canonical relationship matrix by grouping the elements into their respective levels. The reachability and antecedent sets of variables are constructed from the final reachability matrix. Reachability sets are formed by the factors related (with value of 1) into the horizontal direction while the antecedent sets are obtained from the vertical direction from each risk factor. Intersection points are identified when the same set appears in both columns.
- Construction of the ISM model: The set of variables into their respective levels are linked according to their relationships as defined by the self-structural interaction matrix.

- Z1, independent factors: on this zone lies seven risk variables, around 32% of risk factors. This zone represents variables that are little dependent but most conductive. Variables on this zone are labor force unavailability risk (R2), technology and innovation risk (R3), transport risk (R6), natural hazards risk (R11), energy price variation risk (R16), ecological damage risk (R18) and public policy and regulatory risk (R20). Some transformation on those risk factors on this zone would affect the whole system. It is important to understand which variables can be prioritized to design mitigation strategies by the companies on this zone. Transportation risks (R6) and Technology and innovation risk (R3) could be monitored to implement action strategies to guarantee a better performance of the system. Variables not under control need to be supervised, in an attempt to prevent changes and improve mitigation strategies, as natural hazards (R11) and public policy and regulatory risks (R20).
- Z2, autonomous factors: this zone identified three risk factors, demand risk (R8), losses by wind quality risk (R14) and IT/communication risk (R19). Those risk factors, with less conductivity and dependence on the system, are variables that demand less attention at the current situation. The Brazilian wind power industry is expected to keep growing, which is the reason why factors such as demand, and wind quality are considered under control and do not represent considerable risk levels to the system. The wind power projects are characterized by high investment in the latest technology, including implementation of IT/communication technologies, which qualifies them as autonomous risks into the system.
- Z3, linkage factors: this zone is characterized by risk factors that are most conductive and dependent. That is, variables affected by changes into the system, and at the same time, conducting to others. Those risk variables are positioned usually in the middle of the model linking the top and bottom levels. Four risk factors (around 18%) were identified into this zone: financial risk (R1), supply risk (R5), construction risk (R7) and operation and maintenance risk (R10). A change into those risk variables leads to instability into the system.
- Z4, dependent factors: with seven risk factors (32%); public opposition (R4), delays risk (R9), legal and responsibility (R13), interconnection network failure risk (R15), third-party service risk (R17), quality risk (R21) and security risk(R22). Those risk factors are characterized by their high dependence, absorbing more easily the changes on the system, but at the same time, lower conductivity. Those variables can be followed as indicators of the stability on the system, because the observation of changes on those variables could indicate any other factor affecting the system stability.
