design the perfect power plant. In several points of view - build expense, UPS, reliability, easy to use, design beauty and efficiency.
the blueprint book starts from 1 core then could be upgraded on the same spot up to 4 cores.
Blueprint design reserves the space in advance so you can plan your factory ahead without spending all the resources at once
The blueprint book suits for early game by cheap start, also suits late game because it fits into Megabase city block design. (More on Nilaus's Youtube )
The Perfect CloverLeaf book
contains 4 variants to choose from 40 / 160 / 280 / 480 MW . It is designed to be built on top of each other.

You know the space from start, so factory can grow around.
It is friendly for pocket roboport build, so there is enough of space to let you walk inside.
It is belt based, but you can replace wood boxes in current build by requester logi-chest and you are ready to go for bots.
It has 6 incoming water pipes which can be 200 pipes long to shore pump without additional pumping.So you can build it almost anywhere, no lake and heap of land fill needed.
It is saved with landfill, just for case.
It is compact square 58x58 tiles
Easy Activation
In the upper right corner you see a constant combinator between two wall pieces, turn it ON then OFF again. It will start to load fuel. Constant combinator simulates a signal taking burned fuel out, so system puts the fresh in. After this, all is automated.
Perfect output
dead straight line of 83 turbines producing 483,06MW.
Losseless & Brownout prevention
In the Factorio CheatSheet you can find information that 4 cores loss-less need 40 steam tanks. There is an inconspicuous note down-there "not including heat stored in the reactor or pipes (both heat and steam). " That note means, you actually need 3 ( yes t h r e e )

We see that 3 steam storages are enough so why I used 8?
1.Because of Brownout prevention. When plant is re-started, all parts starts at 500C. Steam is produced since 501C, but heat-pipes spread the heat with delay. Meanwhile you are heating up the system, the plant need to consume reserve steam to prevent brownout. So it is wise to create the shortest heat-pipes to Heaters to cut down heating up period. For this compact design, 10s of steam reserve would be ok, so 5 Steam storages (13seconds) is safe.
2. Steam storage or piece of pipe are the same liquid object (compute price-wise) so UPS expense are the same. Steam storage cover bigger space than pipe so in current design I can remove 3 tanks but need to add 6 pipes. Which means I would get 3 more liquid objects to count. Therefore 8 storages.
3. Extra 3storages gives a bit more headroom on bumpy roads like unexpected steam drops when feeding coal liquification process, or fill up a train with steam tank wagons
4. design symmetry, it just looks better
I know it is about 120 iron plates more expensive, but I can swallow it.
Two power grids feature
when you get out of power (for some reason), you can chicken out and eventually re-start a power plant manually feeding it by hand. However, when you using fluid pumps it become task close to impossible.
So here comes the smart design which ensures, the mission critical systems are in separated power grid, with own power source. Result is, the power plant always able to start up itself, without hand touching it.
There is also a subtlety, when combinator uses pulse read mode and is underpowered (brownout) then it miscalculates. It is a intended feature by game design. Therefore, is wise make sure your combinators counting fuel don't miscalculate, ever.
Combinators
There are three circuitry
Bonus build Fuell cell (re)processing
a compact fuel cell (re)processing facility. It turns on itself only when needed and (re)produce as much fuel cells as needed. Fun to watch.

Edit:
Update1: Removed 80pipes, one combinator and made b-print smaller by 4 tiles. Now 58x58. It is saved with landfill, just for case.
Update2: added power per tile measure, added info about brownouts on combinators, improved 4 core overview picture so there is a bill of material now.
