CITY RESIDENTS will continue to face a torrid time during peak summer season for the next two years as the Chandigarh electricity department will have insufficient power.

The power shortage has been pointed out in the load forecasting study for long-term power planning conducted by a private firm for the department.

As per the power projection for the year 2017-18 and 2018-19, the department will have deficit power during peak hours despite having overall excess energy. Peak hour refer to a period of high consumer demand. As per the peak projection for year 2017-18, the department will have a deficit of 112 megawatt (MW). Against projected peak load of 477 MW, the department just has 304 MW. In the subsequent year, the deficit will increase to 130 MW. Against demand of 496 MW, department has arrangement for 366 MW.

The electricity department does not have its own power generation source and purchases power from central generating stations such as National Thermal Power Corporation Limited (NTPC), National Hydroelectric Power Corporation (NHPC), Nuclear Power Corporation of India Limited (NPCIL), Bhakra Beas Management Board (BBMB), Satluj Jal Vidyut Nigam (SJVN) and Tehri Hydro Development Corporation Ltd (THDC).

The report has suggested that the deficit power requirement can be sourced from long-term power purchase agreements (PPA’s) and other bilateral agreements. The deficit will result in high peak stress on an already ageing and capped distribution system of the department, thus causing break downs. This year, residents, especially in southern sectors faced a harrowing time due to frequent outages caused by overloading of the system during peak summer season.

As per official records, presently, there is only one 220 KV substation. There are 13 66 KV substations and five 33 KV substations in the city. Each sub-station has a life span of 25 years and around six 66 KV substations are over that time span. The study has laid emphasised on taking corrective demand side management measures to curtail the peak demand.

The electricity department caters to 2.12 lakh consumers, out of which 1.75 lakh are in the domestic category.

The department has submitted the study to Joint Electricity Regulatory Commission (JERC) for approval so that corrective steps can be taken. The hearing is scheduled for September 16.

UT superintending engineer MP Singh said they had got the study conducted to ascertain the actual load requirement in the coming years.
“ Overall we have surplus power for next two years, but there is some deficit during the peak hours. We will make efforts to overcome the deficit,” said M P Singh.
