Honestly talking about railgun on Type 052C/D there is zero chance
Type 055 probably produces a lot of excess electrical energy but railgun uses a astonishing amount
Not only that you need a huge excess
If the rail uses 25MW then you need a excess of 35MW
I reckon with right turbines Type 055 produces probably 50MW
Say the ship itself based on its size consumes 10-15MW there is certainly enough for rail gun
But definitely not on Type 052C/D
Zumwalt which is larger produces 78MW, users 20MW leaves 58MW for rail gun

How do you arrive at those power generation numbers? I don't know any better, just wondering.

By those calculations, the current 072III landing ship shouldn't be able to host the rail-gun either, but it can, with additional generators.
With the current power supply, it's likely true that the 052C/D cannot power a rail-gun but we were just discussing making room on the 052 and 055 hulls for the addition of rail-gun power generators to be installed. From what you say, maybe the 055 won't even need it but for 052, I say there is room to add them. I made some suggestions here: https://www.sinodefenceforum.com/type-055-ddg-large-destroyer-thread.t6480/page-515#post-494037
Of course, simply being possible does not mean it will happen.

Depending on how confident the PLAN is with the EM gun, whether it's already been planned for integration with a ship design or not namely the 055, how conservative they want to be with trying it out in service, and of course to test out if it's technically feasible, I would think that it costs less and tests more to integrate the EM gun on a single 052D to the extent of removing the gun CIWS or even some VLS modules to make room than it is to do it on a 055.
Didn't people say 055's propulsion is 112MW and Zumwalt is 78MW?
If it turns out to be true, then energy source is not a blocking issue. Everything is planned nicely, in some aspects more practical than Zumwalt, in some other aspects more aggressive.
As to 052 series, no I don't think it would mount railgun or laser. That would be a surprise.

The 112MW figure is the estimated shp delivered by the 4 GT in 2x COGAG config. Electrical power is provided by 6 GT power generator sets providing anywhere from 18MW (lower estimate) to 48MW (upper estimate) of electrical power.
The Zumwalt has a lot more flexibility with its power distribution than the 055, as its propulsion is electric driven.

From the picture below, the ship beside the 072 LST seems laden with electric equipment and electrical panels. Curious that they are heat generating and why are they painted black in addition to being in the hot sun.
But the point I want to make is that if the LST plus additional containerised generators are enough to power the rail/coilgun, why is the ship beside it carrying so much electrical equipment? The ship beside it seems to be a support ship. Why does a support ship need so much electrical equipment? A support ship for a complex rail/coilgun would probably need to have data servers and advanced electrical diagnostics equipment (oscilloscopes etc.). But those aren't necessarily voluminous as to need to be distributed throughout the ship next to the LST. There are full 2metre height standing panels (beige coloured with their own roof) even on the 'roof' of that ship as well.
Well we all know the current 055 doesn't have railgun. I thought we are talking about its next iteration once it has IEP. My understanding is that China's IEP is more mature than its railgun, doesn't make sense to have railgun but no IEP (retrofitting current 055 with railgun is another story). My question would be whether this 112MW figure is true or not. If it is, then it's a huge advantage against Zumwalt.
