The order to � seek and destroy�. Recovery teams are trying to salvage the wreckage. Youre watching bbc news. Now its time for powering ukraine. Russian missiles and drones rain down on ukraines civilian infrastructure, causing untold damage. Its been happening for months. This is ukraines energy war, a constant battle for heat and light, with an army of engineers racing to keep the country connected. For ukrainians, it has been a winter of darkness and uncertainty. How does a country respond when the stakes are so high . If the power system collapses, that would mean the suffering of tens of millions of people during wintertime. We cannot allow that, not on my watch. We follow the teams fighting this war. What the missiles destroy, they rebuild, in places where people are living on the edge. This power plant in Central Ukraine has been hit repeatedly. Its a huge place, but this is what well aimed russian missiles have done to the countrys infrastructure. Missile fragments litter the place. For security reasons, we have been asked not to identify the plant or its manager. So what happened here . This is where electricity begins its journey from the power plant to the world outside, the first links in a complex chain. Since october, moscow has been working systematically to sever those links, to break the system into pieces, to break the will of the people. Every corner of this huge complex bears the scars. While the threat still exists, not everything will be repaired. Millions of people depend on this coal fired Power Station, built in the soviet era, its great turbines turning away at the heart of ukraines sprawling power network. Fantastic machine. The system now generating half as much electricity as it did a year ago. The staff here know they are in russias sights. Ihor is the plants chief technician, on duty the morning of the first attack. When he arrived here in the main control room, he found a chaotic scene. So the whole Power Station is run from this room. Did all of this get switched off . It has been weeks since the last attack here, but this morning the alarms keep coming. Siren so theres the siren. We had been expecting it this morning. We have to get out of the turbine hall and head straight for the shelter. Incoming missiles have been detected, flying towards ukraine from the south and east. There is time to take cover. On days like these, hours are spent underground. Anxious moments as news comes in of a fresh wave of attacks. Their colleagues at a Power Station in the west have taken a direct hit. They know this could have been them, and closer to home, word is spreading of something much worse. Across town, a tragedy is unfolding. A missile has struck an apartment building. The Rescue Effort is frantic. Dozens of people have died here. The missile that did this was huge. Designed half a century ago to destroy aircraft carriers. It was almost certainly aimed at the Power Station. Some of russias attacks are accurate. Many are not. Russias assault has brought death and darkness to ukraines cities. The nights are long and cold, the power cuts frequent. A whole nation plunged into a world of adjustments. For david, not yet two, it is mostly a game. Thats how his parents prefer to keep it, especially when sirens wail and missiles fall. Its 8 30. A power cut is coming. Its time for bed. Here we go. Yes, yes. There we go, it is 9 20 and a few minutes late but the power cut has begun. After months of this, the fear and the novelty have long gone. This is how millions of ukrainians have learned to spend their evenings unfazed, organised. This war on energy is notjust about ukraines Power Stations, its about the entire infrastructure, the grid that keeps this vast country with electricity and heating. And its that grid that has been hit over and over again since october. Were off down a rather bumpy road to see a piece of that grid now. And again, we cannot tell you where it is. This is serhiis substation. The place where he has worked for 30 years. Since september, he has watched it being demolished, bit by bit, six separate attacks. Four months ago, he saw a kamikaze drone destroy the control room and his office, knocking the whole substation off line, cutting power to millions of people. The attackers knew exactly what they were doing. The substation� s 750 kilovolt transformers wont be easy to replace. They weigh 300 tons and take months to produce. Only three or four countries in the world make them. One of them is russia. Ukraine is scouring the globe, looking for substitutes. We are far from this war� s frontlines but everyone who works here feels like a soldier. In this forest of machinery, there is a quiet, steely determination. Do you feel angry . For who . We travel on south, towards frontline communities under regularfire. Ukraines battalion of engineers racing from one repairjob to the next. Speaks ukrainian. This happens all the time, volodymyr tells me. Were on our way to a village shelled just last night. The power lines are down, again. The repairs wont take long but the men know they will be back. The battle to keep ukraine connected takes many forms repairing wires, diverging power, concealing what is and is not working. Its a constant struggle, fraught with danger. Distant explosions. In the nearby village, the sound of artillery has the Mayor Ducking for cover. How long do you think you can carry on living here in this situation . Or do people want to leave . In places where the frontlines have moved, theres other work to do. Here, teams are busy reconnecting towns and villages cut off behind russian lines for months. Where the army has been, the engineers must follow. Speaks ukrainian. Fedir is another veteran. His home town is under regular attacks so his wife and grandchildren are living in poland. He is out in the field every day. Pylon by pylon, cable by cable, connections are re established. These are battered places, scarred by recent conflict. Fresh graves speak of long, difficult months and long, difficult lives. The engineers wait as Emergency Teams go ahead, inspecting the ground, looking for discarded weapons. Its slow, painstaking work. How long do you think it will take to fix everything . And while the country waits, it simply copes. City streets echoing to the sound of generators. Mobile phones lighting the way. Life somehow continuing. And a mounting sense that ukraine has, for now, weathered the storm. This battle is finely balanced between russias ability to inflict damage and ukraines efforts to repair it, to give peoplejust enough power to get by. Those who run the grid have no illusions about the struggles ahead. Russians failed to take down our system or to cause big disturbance in our system. Having said that, unfortunately, they are gradually destroying very important items of equipment in our grid which takes time to be restored. And yet, despite all of this damage, as you travel around this country, it becomes obvious that ukraine is not on its knees. We were prepared and we were very resolved to win this particular bout. We have no other way but to win because if we lose, if our system collapses, that would mean suffering of tens of millions of people during wintertime. We cannot allow that. When i am asked this question, i often say, not on my watch. And if somebody told me before that our power grid could stand like 1000 missiles and drones and still run and still deliver power to consumers, i would probably not believe it but now, we know that we are resilient and we are much more ready now for the new attacks than we have been on the 10th of october. Russia thought it would break ukraine but its campaign isnt working. Half the grid may be in tatters but in helmets and body armour, these men are keeping it alive. The war� s terrible cost is evident wherever you look. The sacrifices have been immense. But power, the lifeblood of a nation, still reaches across the land. Hello there. For the first half of the weekend, sunshine was in relatively short supply. Many of us got stuck with a lot of cloud, but there is a better chance of brightness over the next few days and it is going to stay largely dry and generally very mild for the time of year. Now, on the earlier satellite picture, you can see the cloud thats been feeding in from the west. Its Eastern Parts, Eastern Parts of scotland, Northeast England that had the best of the sunshine on saturday with a little bit of shelter. Now for sunday, as this area of High Pressure slips a little further eastwards, the breeze will pick up around western and northern parts of the uk, and that should allow for a bit more in the way of sunshine. Cloud, though, could be thick enough in the northwest of Scotland First thing to bring some spots of drizzle and its likely to cross central and Eastern Parts of england, cloud will tend to linger through the day. The winds here will stay light, but further west and further north, a brisk breeze which will help to break the cloud up and give a bit more in the way of sunshine. It is going to be another mild day with temperatures of 10, 11, or maybe 12 degrees. But through sunday night, as we see a few more holes in the cloud, a few more clear breaks, temperatures are likely to drop. We could have A Touch Of Frost in places, but its likely that for central and Eastern Parts of england, there will be more in the way of cloud. So temperatures here should hold above freezing. Also, Northwest Scotland staying a little bit milder because there will be more of a breeze. This is how we start the new week. This really sets up the weather story, actually, for the first few days of the week, High Pressure trying to hold on to the east of us, this frontal system trying to push in from the west. But its going to take a while to do so. And actually, with more of a southerly breeze on monday, more of us should get to see some spells of sunshine. It is likely to be Eastern Parts of england that hold on to the cloudiest of the conditions. Temperatures 9 degrees for stornoway, for aberdeen, 12 for london and for plymouth. Now for tuesday morning, we could well see some quite dense fog affecting parts of east anglia, the southeast, the midlands, perhaps east wales and the west country. That could be worth bearing in mind if youre planning to travel on tuesday. Should tend to clear, though. Then well see some spells of sunshine, another mild day, but cloud and patchy rain getting into parts of Northern Ireland and western scotland. The first sign of a change. Now this frontal system is likely to move in from the west quite erratically, and there is a bit of uncertainty aboutjust how quickly it will make its move. But there is the chance, certainly the increasing chance of some rain pushing from the west towards the east as we head through the day on wednesday. Eastern parts of england likely to stay dry for a good part of the day. And its another mild day, 9 to 13 degrees. Now, once that Weather Front has pushed through, that opens the door to further Weather Systems from the atlantic. So there will be some outbreaks of Rain Somewhere across the uk on thursday, perhaps chilly enough in the north of scotland for some wintry showers. But generally speaking, it is another mild day. Now, as we look further ahead through friday and into next weekend, you can see that further frontal systems will push in from the atlantic. So therell be further outbreaks of rain at times, however, High Pressure never too far away. It may start to build back in again from time to time. That would give rise to some drier interludes. So, this is the outlook through the end of the week and into next weekend and indeed beyond. Some rain at times, but not all the time. Some drier interludes. And certainly for the time being, the weather looks like staying very mild. Welcome if youre watching this is bbc news.
