I suppose that's an added bonus, but I'd say this was planned before the tanker business. It may also have been a test of the Oreshnik's ability to penetrate deep enough to compromise the gas storage facility in the rock layers., not directly (I don't think it can penetrate that deep - 800m) but via possible knock-on tectonic effects.
That was also my first thought, that the attacks were planned beforehand.
Klitschko advices some residents of Kiev to leave the city when they can since about 6.000 apartment buildings are without power, mainly heating.
Unfortunately, I don't have a better source, since RT English gets blocked:

According to Klitschko, "half of Kyiv's apartment buildings - almost 6,000 - are currently without heat supply due to critical infrastructure damaged by the enemy's massive attack on the capital." Also, according to him, "there are interruptions in water supply in the city." "Utility workers have powered social institutions - in particular, hospitals and maternity hospitals, from mobile boiler houses. And together with energy workers, they are working to restore electricity and heat supply to Kyiv residents' homes," Klitschko said.
According to him, the capital is doing "everything to do it as quickly as possible."
And now of course Ukraine wants an immediate UN security council meeting.
