About this statute
These Regulations may be cited as the Electricity (Wayleave Title and Clearances) Regulations, 2026. This section defines key terms used in the Regulations, including clearance, competent person, developer, overhead line, wayleave, and related electricity-safety terms. These Regulations apply to certain structures, overhead lines, developers, and installations, but not to wiring of premises or scientific-study installations; excluded scientific-study installations still need supervision and safety compliance. A licensee or developer must construct, operate, and maintain an overhead line and underground electricity cable according to the Schedule. People, planning authorities, and licensees placing electricity infrastructure must meet the Schedule’s minimum overhead-line wayleave requirements.

AI-assisted research summary: This provision gives a calculation method for minimum wayleave width for parallel overhead lines at different voltage levels.
2.1.41 Sample calculation of wayleave for parallel overhead line of the same Voltage level (for 11kV to 132kV overhead line) The 66kV to 132kV overhead line model in Figure 2.1 shall be referred to for calculation of Wayleave widths in this paragraph. Figure 2.1: 66kV to 132kV Over head line model 2nd January, 2026 Statutory Instruments 11 The parameters involved for calculation of wayleave width for parallel overhead line of same voltage level are: (a) (b) (c) ‘W’, which is the minimum total wayleave width; ‘a’, which is the maximum distance between the outer conductor and the edge of the wayleave, and can be obtained from the last column in Table 2.2; (For overhead line configurations as depicted in Figure 2.1, clearances and dimensions for a and g are the same). ‘b’, which is the minimum maintenance clearance. Maintenance clearance and conductor clearance for various voltage levels are provided in Table 2.3. Conductor clearance is clearance between the nearest conductor of an overhead line and the tower structure; (For overhead line configurations as depicted in Figure 2.1, clearances and dimensions for b, d and f are the same). (d) ‘c’, which is conductor clearance plus maintenance Clearance. (For overhead line configurations as depicted in Figure 2.1, clearances and dimensions for c and e are the same). From Figure 2.1 and the minimum clearance between conductors of parallel lines as given in Table 2.1 and Table 2.3, the width for wayleave for three parallel overhead line can be determined from the following equation: W = a + b + c + d + e + f + g (1) But for parallel lines of the same Voltage level, a = g, b = d = f and c = e. Therefore, Equation 1 simplifies to: W = 2a + 3b + 2c (2) For respective Voltage levels, the minimum values of ‘a’ are given in Table 2.2, the values of ‘b’ are given in Table 2.3 and the values of ‘c’ (conductor clearance plus maintenance clearance) are determined from Table 2.3. (a) Calculating wayleave width for 3 x 132kV parallel overhead line For 132kV overhead line, a = 12m; b = 5.5m; and c = 8.25m (i.e. 2.75m + 5.5m). Hence, using equation 2, the minimum required wayleave width for three parallel 132 kV overhead line would be: W = (2*12) + (3*5.5) + (2*8.25) + 57.0 meters (b) Calculating wayleave width for 3 x 88kV parallel overhead line For 88kV overhead line, a = 10m; b = 5.5m; and c = 8.0m (i.e., 2.5m + 5.5m). Hence, using equation 2, the minimum required wayleave width for three parallel 88kV overhead line would be: W = (2*10) + (3*5.5) + (2*8.0) + 57.5 meters 12 Statutory Instruments 2nd January, 2026 (c) Calculating wayleave width for 3 x 66kV parallel overhead line For 66kV overhead line, a = 10 m; b = 5 m; and c = 7.5 m (i.e., 2.5m + 5m). Hence, using equation 2, the minimum required wayleave width for three parallel 66kV overhead line would be: W = (2*10) + (3*5) + (2*7.5) + 50.0 meters (d) Calculating wayleave width for 3 x 33kV parallel overhead line (Horizontal arrangement) For 33kV overhead line, a = 5 m; b = 4 m; and c = 6.5 m (i.e., 2.5 m + 4 m). Hence, using equation 2, the minimum required wayleave width for three parallel 33kV overhead line would be: W = (2*5) + (3*4) + (2*6.5) + 35.0 meters (e) Calculating wayleave width for 3 x 11kV parallel overhead line For 11kV overhead line, a = 4m; b = 3.5m; and c = 5.5m (i.e., 2m + 3.5m).

1.4.2 Sample calculation of wayleave for parallel overhead line of the same voltage level
AI-assisted research summary: This section gives a formula and sample figures for calculating the minimum wayleave width for parallel overhead lines above 132kV.
2.1.4.2 Sample calculation of wayleave for parallel overhead line of the same voltage level (for overhead line above 132kV) The 220kV to 330kV overhead line model in Figure 2.2 shall be referred to for calculation of wayleave widths in this paragraph. Figure 2.2: 220kV to 330kV overhead line model 2nd January, 2026 Statutory Instruments 13 The parameters involved for calculation of wayleave width for parallel overhead line of same voltage level (above 132kV) are: • • ‘W’ which is the minimum wayleave width; ‘a’ which is the maximum distance between the outer conductor and the edge of the wayleave, and can be obtained from the last column in Table 2.1 (For overhead line configurations as depicted in Figure 2.2, clearances and dimensions for a and j are the same). • ‘b’ which is the minimum maintenance clearance. Maintenance clearance and conductor clearance for various voltage levels are provided in Table 2.3. Conductor clearance is clearance between the nearest conductor of an overhead line and the tower structure or ground. (For overhead line configurations as depicted in Figure 2.2, clearances and dimensions for b, d, e, f, h and i are the same). • ‘d’ which is conductor clearance plus maintenance clearance. (For overhead line configurations depicted in Figure 2.2, clearances and dimensions for c and g are the same). From Figure 2.2 and the minimum clearance between conductors of parallel lines as given in tables Table 2.2 and Table 2.3, the width for wayleave for three parallel overhead line above 132 kV can be determined from the following equation: W = a + b + c +d + e + f + g + h + i +j (3) But for parallel lines of the same voltage level, a = j, b = c = e = f =h = i and d = g. Therefore, equation 1 simplifies to: W = 2a + 6b +2d (4) For respective Voltage levels, the minimum values of ‘a’ are given in Table 2.2, the values of ‘b’ are given in Table 2.3 and the values of ‘d’ (conductor clearance plus maintenance clearance) can be determined from Table 2.3. (a) Calculating wayleave width for 3 x 330kV parallel overhead line For 330kV overhead line, a = 15m; b = 7.8m; and d = 13m (i.e., 5.2m + 7.8m). Hence, using equation 4, the minimum required wayleave width for three parallel 330kV overhead line would be: W = (2*15) + (6*7.8) + (2*13) + 102.8 meters (b) Calculating wayleave width for 3 x 220kV parallel overhead line For 220kV overhead line, a = 15 m; b = 7.45 m; and d = 12 m (i.e., 4.5 m + 7.5 m). Hence, using equation 4, the minimum required wayleave width for three parallel 220kV overhead line would be: W = (2*15) + (6*7.45) + (2*12) + 98.7 meters 14 Statutory Instruments 2nd January, 2026 - 2 Verify source ↗

AI-assisted research summary: This provision gives a sample calculation for the wayleave of a parallel overhead line with mixed voltage levels.
2.1.4.3 Sample calculation of wayleave for parallel overhead line of mixed voltage level one 220kV overhead line and one 66kV overhead line. For 66kV overhead line, a = 8 m, b = 2.5 m. For 220kV overhead line, c = 4.5 m, d = 15 m (maximum distance ‘d’ from Table 2.2 is given to highest voltage level of the two). Between two lines, the center distance is 32 m (value of the highest of the two Voltage levels; refer to Table 2.1). Therefore, W = (a + b) [for 66kV] +32+ (c + d) [for 220kV] W = (8 + 2.5)+32+(4.5 + 15) = 62.0 meters. - 2 Verify source ↗
