Supplier
The energy supplier buys electricity and/or gas at an exchange and then sells it to us, the consumers. Each customer selects their supplier on their own and can therefore influence the final price that will be billed for their electricity and/or gas consumption. The reason is that each supplier has the right to determine by itself the unregulated part of the price, which is not subject to control in any manner, of its price. This is also the reason why there are multiple offers quoting different prices in the market.
The supplier usually also arranges for the contract with the distributor (the customer then has a contract for bundled supply services) who physically transmits/transports the energy to customers.
My Supplier
My supplier is the entity that supplies me with gas and/or electricity, with which I have in place a contract for bundled gas and/or electricity supply services, to whom I pay advances, and from which I receive the gas and/or electricity bill. You can find information about the supplier in your contract and bills.
DSO = distribution system operator
The DSO, or the distribution system operator, physically transmits/transports electricity or gas. The DSOs do not sell electricity or gas. Suppliers sell energy. DSOs operate as natural monopolies and the ERO therefore controls the prices for their services.
My DSO
You cannot change your DSO. The DSO is determined by the defined terrritory. The main DSOs include
- for electricity, ČEZ Distribuce, a.s., EG.D, s.r.o., and PREdistribuce, a.s.
Supplier of last resort
If your energy supplier discontinues its activities, the supplier of last resort steps in to replace your supplier (temporarily).
The supplier of last resort is obliged to immediately inform you about starting electricity and/or gas supply to you, the prices, and the terms and conditions of such supply.
You can enter into a new contract with any supplier or select a standard product from the supplier of last resort within six months.
