as the current experimental e-net is, i don't care for it. it isn't the cables, it is the storage blocks. you used to be able to pipe in the eu limit per side. now it is cumulative. IE 32 eu max from any source into a batbox, and so on.
this becomes difficult with generators that fluctuate the amount of power they output, especially in tandem. i just blew up a cesu because i had one line running 128eu/t to it from a reactor, while a line from my passive generators was supplying 12eu/t.
this adds a bit too much rigidity to power grids. all my power basically now has to be routed to a single storage block, and has to be less than that block's max intake. i then have to step it through my base, with no auxiliary power feeds in.
so rather than rant and run, i'm going to make a suggestion: capacitors.
a capacitor would be a transformer-storage hybrid. it would accept up to 1 tier above it's output(cumulative), and would buffer the excess energy(appropriate for it's tier) when space is available. functionally, it would be no different than putting a batbox directly behind a transformer, with one exception...if it's capacity is exceeded, it will stop working rather than blow up...unless a full 2 tiers of excess power is applied (ie 512+ to a 32 eu capacitor). this block would need to be manually reset by the player in the block's gui(no redstone reset). The capacitor would then start blinking and/or buzzing. a circuit breaker is something i have long wanted to see in IC2. redstone behavior would be emit if storage is empty, breaker is tripped, eu in storage, internal storage full, power is entering and/or leaving, etc. optionally, the capacitor may heat up and trip if the internal storage is full for too long. a display in the gui as to why it was tripped could be useful aswell.
