The connection procedure for a project under the Netbilling Law has 6 stages, which are explained briefly below . This procedure is designed to allow a low cost to the user and be expeditious (can take between 4 to 6 months)

• Stage 0: Optional, it corresponds to a request for information to the distribution company.
• Stege 1: Connection request to grid (SCR): The user must specify the main characteristics of his generation system (location, installed capacity, etc.).
• Stage 2: After receiving response to the connection request from the previous stage, the user must make a statement of compliance to the SEC.
• Stage 3: Corresponds to the period of installation and registration of generation equipment in the SEC (TE4 statement).
• Stage 4: Notification of connection and signing of contract with the distribution company according to the connection protocol.
• Stage 5: The connection to the distribution network occurs.

It is important to note that all forms and the Online Connection Processing platform for each of the communications with both the distribution company and the SEC are available on the website of the SEC[33], as well as the maximum deadlines for response of all parties. Annex 4 presents in more detail each of the stages and on the SEC website [34] the procedure of connection and commissioning.

The procedure for connecting and commissioning a PMGD can be found on the SEC website[35] and Annex 4 describes in greater detail each of the stages of connecting a PMGD. It is important to indicate that PMGDs can request to be classified as Not Significant Impact (INS)16  in which case the connection procedure is different. The stages for connecting a PMGD are as follows:

• Stage 0: It is optional, it corresponds to the request for information and response from the distributor..
• Stage 1: Sending the Network Connection Request (SCR).
• Stage 2: Declaration of admissibility
• Stage 3: Response to the Network Connection Request (SCR).
• Stage 4: Conformity with the response to the (SCR).
• Stage 5: Issuance of the Connection Criteria Report (ICC).
• Stage 6: Declaration under construction.
• Stage 7: Commissioning and Entry into Operation

It is important to note that the PMGD technical standard for connection and operation explicitly incorporates the definition of “shared facilities”, clarifying the rights and conditions to install PMGD in installations that also have consumptions. That is, for certain projects the standard does not oblige to build a new joint, but allows to take advantage of the existing joint.

Each of these stages has one or more pre-established forms through which communications are made between the customer, the distribution company and the Superintendency. Likewise, the deadlines that the parties have to respond to are also regulated.

According to what is established in the Law, the installations of the National Transmission Systems and the transmission systems of each electric system are subject to an open access regime and can be used by third parties, under non-discriminatory technical and economic conditions among all users.

Also, Dedicated Systems are also subject to the open access regime, i.e. owners can not deny the service to any interested party when there is available technical capacity of transmission. The Coordinator will reasonably determine the available technical capacity of the Dedicated Transmission Systems.

In accordance with current regulations, the interconnection of all facilities must be communicated to the CNE, the Coordinator and the SEC at least six months in advance. The energization of any facility must be reported to the SEC, at least fifteen days in advance.

The design and information requirements to be delivered by the generators are described in detail in the NTSyCS, which are valid for any generation medium that is integrated into an electric system.
