Reliability of supply and transparency of tariff index (0-8) (DB16-20 methodology) This index ranges from 0 to 8 and is calculated on the basis of the following six components: (i)Duration and frequency of power outages (0-3); (ii) Tools to monitor power outages (0-1); (iii) Tools to restore power supply (0-1); (iv) Regulatory monitoring of utilities' performance (0-1); (v) Financial deterrents aimed at limiting outages (0-1); and (vi) Transparency and accessibility of tariffs (0-1). An economy is eligible to obtain a score on the reliability of supply and transparency of tariffs index only if (i) the utility collects data on all types of outages (average total duration of outages per customer and the average number of outages per customer), including planned and unplanned outages, as well as load shedding, with the minimum outage time of not more than 5 minutes; and (ii) the SAIDI value is below a threshold of 100 hours and the SAIFI value is under 100 outages.
Type of variable: Continuous
