5.2. Processing of technical permits
The procedures and formalities necessary to manage the entry into operation of a NCRE project are specified in the regulations indicated above. As described above, the connection procedure and the permission to enter into operation depends on the system in which the NCRE generator is connected.
The procedure for connecting a project under the Netbilling Law has 6 stages, which are explained briefly below and in more detail in Annex 4. 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 and initial stage corresponds to a request for information to the distribution company mainly to know the installed capacity allowed.
Stege 1: Connection request: 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 or express nonconformity to the SEC if applicable.
Stage 3: Corresponds to the period of installation and registration of generation equipment in the SEC.
Stage 4: Notification of connection and signing of contract with the distribution company.
Stage 5: The connection to the distribution network occurs.
It is important to note that all forms for each of the communications with both the distribution company and the SEC are available on the website of the SEC, as well as the maximum deadlines for response of all parties. Annex 4 presents in more detail each of the stages and Figure 28 presents the procedure of connection and commissioning.
The procedure described above has regulated periods in which the distribution company must respond to the different requests of the customer, established the total terms for all the processing of the system, between 30 working days for small projects and 60 working days for the rest of the systems.
Figure 29 summarizes the procedure for connecting and commissioning a PMGD, and Annex 4 describes in more detail each of the 7 connection stages of a PMGD. It is important to indicate that PMGDs of less than 1.5 MW may request to be classified as Not Significant Impact (INS), in which case the connection procedure is shortened and faster, since it requires fewer studies and stages. The stages for the connection of a PMGD are the following:
Stage 1: Presentation of the project and information request.
Stage 2: Response to Presentation.
Stage 3: Submit the Network Connection Request (SCR).
Stage 4: Respond to the Network Connection Request (SCR).
Stage 5: Conducting studies (only for PMGDs whose impact is significant).
Stage 6: Connection costs study (only for PMGD whose impact is significant).
Stage 7: Additional works and commissioning.
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 Commission, 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.
