A lack of power injection capability na Campo Belo substation, inside of Minas Gerais, is leaving os integrators Of region worried with the future of the photovoltaic projects of its DG (distributed generation) customers.
Em testimonials granted to the Canal Solar, PROFESSIONALS of the sector reveal that they are having the requests for their access opinions suspended from cemig (Minas Gerais Energy Company) for this reason and not due to the lack of necessary documentation.
According to sources heard in the report and documents obtained by the Canal Solar, companhia Who – in response to requests sent – informing that you will need to make investments on the network and leaving open or just reporting the problem without leaving a deadline to resolve it.
"There is no remaining capacity for the flow of generation from new units connected to the Cemig D distribution network in the region of the municipality of Candeias, Campo Belo substation”, highlights the document sent to the integrators.
The big problem with this, however, is that the filed requests by integrators occurred before do term final for the start of the new compensation rules da 14.300 Law and they are all with doubts that are not being answered by Cemig.
One of the integrators interviewed by the report – who, like the other professionals who chose not to identify themselves – stated that she had ten access opinions (all of them sent between December 21, 2022 and January 6, 2023) suspended by the distributor at the end of January due to the lack of capacity at the Campo Belo substation.
“I understand that Cemig needs to do work to improve the network and injection capacity. Ok, but when will this work come out? Am I going to have to request access opinions now under the current rule, whereas I wanted them under the old rule?”, he asked.
“These are issues that we don’t know how to proceed with. We open complaints with Cemig and what we receive are always ready responses, which do not provide any guidance on what to do”, she highlighted.
The professional also said that Cemig's response includes a telephone number for further information, but that this is the company's general service. “They are common attendants, for basic questions, such as opening complaints and consulting the customer's circuit breaker. There is no technical support in this contact,” she commented.

No answers
Sought by Canal Solar last Monday (20), Cemig's press office informed that it would forward an official position on the situation by Thursday morning (23). However, to date, no response has been provided to the report.
What to do?
According to engineer Joiris Manoela Dachery, CEO of Energês, Situations of distributors such as Cemig responding to requests for DG connections alleging inversion in the power flow or some system disturbance in the distributor's own network have been increasingly common.
“Before, the distributor had to respond and accept each and every connection request, but now it has to identify these cases of flow inversion, for example, and show viable options to eliminate this inversion. It is something that is in Article 73 of the Resolution No. 1.000,” she explains.
“If you received a notification of this type (the same as the integrators mentioned in this report), show article 73 and ask the distributor for viable connections for this project, because it is something that is provided for in Resolution 1.000”, highlighted the professional, informing that they are five options available:
- Circuit reconfiguration and load relocation;
- Definition of other circuits for this connection;
- Connection at a higher voltage level;
- Reduction of injectable potency on established days and times;
- Inclusion in the study of what is the maximum connection capacity for the enterprise where there is no inversion of the power flow.
Still according to the engineer, regarding the consultation notices for the ONS (National Electric System Operator), provided for in Art. 64, when there is interference in the transmission network, the body “has 30 days to respond, in the meantime the deadline connection budget response is frozen, increasing the bureaucracy of photovoltaic systems”, he concluded.

These integrators want Cemig to make investments in expanding the substation, but they themselves do not want to pay TUSD, which would remunerate these investments.
In other words, they want Cemig to work for free or for someone to subsidize their business model.
They live in a fantasy world.
