Below are some related comments on this subject I posted in another thread. I'm re-posting them here since they are relevant to this thread. As of v2.3 Beta 7 your power reserve is capped at 100,000. While some may believe this is too low, it simply isn't.

When I finally researched to the tech level at which I wanted my expeditionary units to be (and all the manufacturing upgrades) I started cranking out an army or borgs and an air force of VTOLs. The power level dropped considerably, but no where near anything close to anemic. If I wanted to, I could've still built a whole new base
kenalcock, in a later post from another thread wrote:The number 100,000 is just the highest strategic power reserves that you can have at any one moment. It is not the total power you can spend during a game (that number is actually infinite). As long as you have an oil derrick and a power generator, you are converting oil to power, which causes your strategic power reserves to grow.
You spend power when you: build buildings or structures, fund research, or produce units, which drains your strategic power reserves. But the amount of power you have at any one time is in a constant fluid state.
Taking into account the maximum number of units and base buildings that Warzone currently lets you have, Zarel is quite correct that 100,000 is a high enough ceiling for any one player's strategic power reserve.
Once a player has amassed a strategic power reserve of 100,000, they simply cannot spend enough power at once to bring their reserve down anywhere close to 0. Even if try to produce 50 double-turret Dragon VTOLs (which by the way fly dreadfully slow), 50 Super Cyborgs, and 50 double-turret Dragon Ground units all at the same time, while continuing to research everything left in the tech tree, you will still have enough surplus power left in your strategic power reserves to have all 15 of your trucks keep building Missile Fortress after Missile Fortress (which I believe is the most expensive structure in Warzone that you can build an unlimited number of).
Without a game mod, only 35 things can actually spend power at the same time: 5 Factories, 5 VTOL factories, 5 Cyborg Factories, 5 Research Facilities, and 15 Trucks. Eventually, the factories will run out of things to spend power it on because the game limits you to a certain number of units. I believe structures are unlimited, so you could just start building Missile Fortresses everywhere. For each structure you build, you will see a dip in your power reserve as power is allocated to construction. But once the structure is fully funded, and construction actually starts, you will see your power reserve grow again because no more power is being drained. And if you had all 15 trucks build one Missile Fortress each at the same time, it would take so long for each construction to finish that your power reserve would likely climb back up to where it was during the construction.
As I was later informed, the Mass Driver Fortress is actually the most expensive structure. Still my example holds true, since the more expensive a structure is, the longer construction takes. And the longer construction takes, the more time for your power reserves to grow again.
