How many people are left without light
Bad weather with snow and wind during the May holidays led to the largest disconnection of electricity in the suburbs over the past decades. Due to the break of the power lines and the trees fallen on them, 760 settlements remained without light, and 4.4 thousand substations were de-energized. Similar problems were observed in the Vladimir region. Most of all, according to the assessment of the authorities near Moscow, the surroundings of the Taldom, Dmitrov and Sergiev Posad, where Blackout lasted several days, suffered for several days. Its main consequences have already been eliminated, although some of the settlements on the evening of May 4 were still without light.
Anomalous for the May holidays, the weather came in the Moscow Region on the evening of May 1. The falling wet snow with the rain is sticking to the trees, which began to fall under the gusts of wind (its speed reached 15 m/c). On the morning of May 2, residents began to share in social networks pictures of snow -covered trees that fell on the tracks and lines of power lines, and entire areas of the Moscow Region were de -energized.
The Rosseti holding (provides power supply in 82 regions of the Russian Federation) immediately appreciated Blackout in the region as “the largest in several decades”, explaining that he had led a powerful cyclone with “record” snowfall and tempting wind.
According to TASS, due to the bad weather, a fall of more than 1.5 thousand trees in 14 districts of the Moscow Region was recorded, and 348 settlements of the region were de-energized. On May 4, the Rosseti was assessed that the power supply had to be restored in 760 settlements of the region. The Governor Andrei Vorobyov reported that 237 power lines and 4.4 thousand transformer substations were de -energized in the region, which affected more than 26 thousand inhabitants. Most of all, he said, the north-west of the Moscow Region, in particular the surroundings of Taldom, Dmitrov and Sergiev Posad, suffered. Later, Mr. Vorobyov said that the consequences of the cyclone « energy were called the most difficult over the past 15 years. » The Rosseti explained that a large -scale Blackout was led to a combination of several factors: the blossomed foliage on the trees, a large amount of wet snow and freezing, which, coupled, caused a massive drop in trees. “We are faced with the need not only to eliminate breaks of power lines and put new supports, but at the same time build new power lines with a length of several kilometers in several territories at once. Including in swamps and in the forests, ”they added in the holding.
Director General of PJSC Rosseti Moscow Region Alexander Pyatigor reported that 230 brigades, 700 specialists and 265 units of equipment were involved in the elimination of the consequences of accidents. According to Andrei Ryumin, general director of Rossetei, 185 power engineers from neighboring regions were additionally sent to the region. By the morning of May 3, power engineers restored the work of 2.5 thousand objects, including 2.3 thousand substations and 183 power lines, according to Rosseti. Work continued all day, but on the afternoon of May 3, according to data TASSremained de -energized 7 thousand inhabitants of the region. In particular, Mr. Pyatigor assured that the light in Klin, Solnechnogorsk and Taldom would be turned on on the night of May 3 to 4. On May 4, the Rosseti reported that they restored the power supply of “most of the consumers that suffered from the elements” in 760 settlements, but the work in “impassable swampy places and forests” continues, and for this it was necessary to involve swamp carriers. For example, in the near Moscow, Istra County, without light on the evening of May 4, there were still 25 settlements, the head of the municipal district Tatyana Vitusheva reported.
The Ministry of Energy of the Russian Federation said that Cyclone also caused a violation of power supply in some areas of the Vladimir region, but there, according to the agency, restoration work was completed on May 3.
Director of the Center for Research in the Higher School of Economics, Sergei Sasim, indicates that the main reason for the power outage of the electric power supply wires was the entire power lines due to the fall of the trees entirely.
“The snow load led to this, which provoked large -scale shutdowns, despite a slight deterioration in the weather,” the expert notes. The width of the security zones along the power lines, in his opinion, could not take into account the height of nearby trees.
In this case, according to him, the power supply was interrupted by household consumers, which are connected in the third category of reliability, which does not imply a reserve power. It is quite strange that a similar phenomenon happened on the networks of PJSC Rosseti Moscow Region, the analyst believes: the past snowfall was predicted in advance by weather forecasters, and the force of the occurreed cyclone cannot be called extraordinary.
