With a capacity limitation contract, you contractually agree with your system operator that you will limit the requested transmission capacity if your system operator requests it. So you mutually agree on a capacity limit where conditions and fees are also agreed upon in advance. Under a capacity reduction contract, you may be represented by a CSP, but it is not required. Even if you are not an authorized CSP yourself, you can negotiate a capacity reduction contract directly with the grid operator. Exceptions are customers larger than 60MW. For this group of customers, according to the Grid Code, they are required by law to always designate a CSP.
