Frequently Asked Questions
How much would I save on my electricity bill if I change to CEMEX Energía?
The savings of each client are different, everything depends on the fee, the location, the consumption profile and the terms of the contract. Contact us to start your process and evaluate your consumption; considering rates, schedules and locations, we will perform an analysis to determine potential savings.
Is there any difference between the energy quality of CEMEX Energía and CFE’s?
The energy we supply is provided through the transmission and distribution network of the CFE, so the quality of the supply is not affected.
If I am a residential user or small business, can I contract the services of CEMEX Energía?
For the residential case, no. For small businesses we do an analysis to calculate the payback period and the energy cost savings.
Will CEMEX Energía install new cabling in order to supply energy, or will existing CFE cabling be used instead?
All the supply would be using the infrastructure of CFE Transmission and Distribution, for which CEMEX Energía pays for its use to be able to deliver to its customers.
If I decide to purchase energy from you, how would I be paying for my services?
It would be through monthly billing. However, your contract with CFE would not end, so an invoice from CFE will continue to arrive for your load points.
What is the usual term of your contract?
We have different options for energy supply and different terms depending on the needs of each customer.
What happens with the meters that I already have?
They must be updated according to the latest official norms and regulations. These requirements depend on the voltage level to which the Load Point is interconnected.
Are the electricity tariffs that you offer, fixed or variable?
We offer both options. Contact us to start your analysis, understand your needs and design a supply proposal that suits your requirements.
Wholesale Electricity Market
What is the Wholesale Electricity Market (MEM)?
It is a market operated by CENACE in which participants may sell and buy electric power, Clean Energy Certificates, Related Services, and any other Associated Product required for the operation of the National Electric System.
What makes up the MEM?
The MEM is composed of: The short-term energy market, the market for the balance of power, the clean energy certificates market, auctions of financial rights of transmission, and medium and long-term auctions.
What is CENACE and what does it do?
The National Center for Energy Control (CENACE) is a decentralized public body whose purpose is the operation of the Wholesale Electricity Market, exercise operational control of the National Electric System and guarantee open access and not unduly discriminatory to the National Transmission Network and General Distribution Networks. Among its main functions are: Plan and control the operation of the National Electric System. Receive offers for energy; Calculate the transaction prices; Give the dispatch instruction to the power plants, as well as the Controllable Demand resources and the transmission and distribution network facilities, and Bill and pay for electricity and Associated Products.
Who can participate in the Wholesale Electricity Market?
Generators participate, Qualified Users - whether on their own account or through a Qualified Service Provider (SSC) -, the exempt Generators represented by an SSC, the Basic Service Providers that supply the rest of the users, the Marketers do not Suppliers that can carry out transactions without representing physical assets and lastly the Last Resort Suppliers that are in charge of maintaining the continuity of the service in case they stop providing the SSC.
What is a Generator?
A generator is a permit holder that has power plants that generate more than 0.5 MW. The generators participate directly in the Wholesale Electricity Market, where they sell their electricity day by day. Likewise, they can participate in the long-term auctions that are held to ensure supply to the Suppliers and make contracts with Qualified Users and Suppliers of Qualified Services to sell their electricity and Associated Products.
What is a Qualified User?
It is an end user that has large load centers (more than 2MW until August 2016 and more than 1 MW from date points) that decides to register as a Qualified User before the CRE, or those loading points under the protection of legacy contracts. Qualified Users can participate in the Wholesale Electricity Market (MEM) either directly or through a Qualified Service Provider. Participating in the market means that they can buy electricity in the day market in advance or in the market in real time, as well as sign contracts with generators that allow them to acquire electricity at an agreed price.
What is a Qualified Service Provider (SSC)?
An SSC is a provider of electric power commercialization services, which buys electricity in the Wholesale Electricity Market (MEM) in order to provide electric service to the Qualified Users with whom it has a supply contract and responds for them to CENACE.
What is a Basic User?
Basic Users are all those users who are not registered with the CRE as Qualified Users. Basic Users can not participate in the Wholesale Electricity Market and, therefore, they need to buy their electricity from the Basic Services Suppliers. The price paid by these users for electricity is a regulated price.
What are the Financial Rights of Transmission?
Transmission Financial Rights are price coverage in different nodes of the system, which obligate and give the right to their holders to pay or collect the price difference that results in the origin node and the destination node of the electricity. These rights do not grant the physical right to use the Transmission network.
What is the Contracted Demand?
It is the demand that the end users or their representatives offer to reduce at a certain moment -in accordance with the instructions of CENACE- in order to maintain the Reliability of the National Electric System, and that it can be used to cover the Power requirements, in accordance with the bases of the Wholesale Electricity Market.
How can I access the transmission and distribution networks?
All power plants and / or load centers that comply with the interconnection requirements of CENACE will have open access and not unduly discriminatory, when technically feasible, to the transmission and distribution networks. To interconnect, power plants and / or cargo centers must sign a contract with the Transporters or the Distributors.
What does it mean that there is open access to the transmission and distribution networks?
Open access implies that any power plant or load center that seeks to connect to the network will have the right to do so under conditions that are not unduly discriminatory, when technically feasible and comply with the interconnection requirements of CENACE.
What does it mean that access to transmission and distribution networks is not unduly discriminatory?
Access that is not unduly discriminatory implies that a person interested in connecting to the network must receive the same treatment as any other person who is in the same conditions, that is, he / she will not be given priority in the hiring, confirmation or assignment of the capacity of the network under criteria different from those established in the applicable legal provisions.
Clean Energy Certificates
What are Clean Energy Certificates (CEL)?
A CEL is a title that certifies the production of clean electrical energy. Generators will receive one CEL for each MWh of clean energy generated to sell in the market. Likewise, the large consumers of electricity, i.e. Qualified Users and Suppliers (SSC and SSB) and other obligated participants, require that a percentage of the electric power they consume comes from clean sources. To verify that they are consuming this percentage, they must buy CEL for the amount required by the Secretary of Energy.
Who must buy the Clean Energy Certificates (CEL)?
Basic service providers Qualified Service Providers Qualified Users that participate directly in the Wholesale Electricity Market; The end users that are supplied by Isolated Supply, and the holders of the Legacy Interconnection contracts that include Load Points whose electric power does not come entirely from Clean Power Plants. In the same way, CEL can be acquired voluntarily, for which it is necessary to be registered as an Entity.
What happens if I change to the new regulation?
When changing to the new regulation, the Generator must adhere to it in all its terms. This implies participating in the Wholesale Electricity Market, both with electricity and with Associated Products (Power, Clean Energy Certificates, etc.), and comply with any other elements required by the Electric Industry Law.
