Any retail consumer of DNO with renewable generation withpeak capacity output of 1 MW or less is eligible.
Only the net monthly consumption is billed plus a minimumpayment (for demand). Credits expires in 36 months.
Consumers may use their credits on others units of their own –stores, houses, etc.
To participate, consumers must apply and receive approval tohave their system interconnected to the DNO grid.
The meter keeps track of how much electricity is consumed andhow much excess electricity is generated by the system and sentback into the electric utility grid.
There is no purchase or electricity selling.

DG main barriers in Brazil
What ANEEL is doing about: Taxes
REN 482/2012• The electricity injected on the grid is a kind of a loan from the
consumer to the DNO.
ICMS Agreement # 6/2013• ICMS (state sales tax) is charged over all consumption, not only over
the net consumption.• This reduces the economic viability of small scale DG.
ANEEL participated in meetings, performed studies,made contributions for a new agreement.
ICMS Agreements # 16 /2015, 44/2015 e 52/2015• Allow SP, PE, GO, RN, CE e TO to charge ICMS only over the net
consumption. MG does it already for the 5 first years after installation(State Law 20.824/2013).
• Revoked ICMS Agreement # 6/2013.

Ofício Circular n° 18/2015-SRD/ANEEL
Allow national and international certification.
The inverters should de certificated by Inmetro from February/2015.
Inmetro Public Hearting to extend the deadline until March/2016.
Authorizes new labs to certificate and suspend the deadline.
Directs that the DNO must accept national and international certification.
What ANEEL is doing about: Inverter certification

Perspectives for small scale DG
DG is getting cheaper
Electricity tariffs are increasing
Consistent regulatory framework
The economic attractiveness is
increasing
Public Hearing 26/2015: amendment in the REN 482/2012 and PRODIST.
• We received 676 contributions from 110 agents: consumers,associations, banks, DNO, generators, manufacturer, universities,consultants, NGO.
• Documents available on PH 26/2015 website:http://www.aneel.gov.br/aplicacoes/audiencia/dspListaDetalhe.cfm?attAnoAud=2015&attIdeFasAud=971&id_area=13&attAnoFasAud=2015
Perspectives for small scale DG
PH 026/2015
Objectives:
• Reduce costs e time to small scale GD connection;
• Elucidate rights and obligations of consumers with DG;
• Increase the scope; and
• Improve information on the bill.
PH 026/2015 - Proposal
• Extend net metering for any renewable source or cogeneration.
• Extend net metering to the power of generation up to 3 MW for hydro and 5 MW for other sources.
• Allow net metering for different consumers in contiguous area (residential and commercial condominiums)
• Not charge the cost of meter change.
• Standardize forms in order do simplify the information and documents the consumers should present to the DNO.
• Reduce the maximum time to connection: from 82 days (actual) to 43 days.
Some contributions were related to:
• Sale the excess electricity
• ICMS• Inverters certification• Founding sources for DG
PH 026/2015
- Other REN object (not REN 482/12).- Only on the free market.
- It is not competence of ANEEL- But we are working...
