Connection Processes (Open Access)

Transelec has clear pre-determined stages for successfully managing Open Access Processes related to companies wanting to connect their projects to facilities comprising the National Power Grid (SEN) by means of existing power transmission lines or substations, as well as the connection of projects related to mandatory Upgrade Plans.

The Open Access connection process is regulated by the provisions of the General Electricity Services Law dated July 2016, specifically Articles 79 and 80. The terms and conditions for applying these articles are indicated in Exempt Resolution N°154 and its amendments issued by the National Energy Commission. According to these regulations, all coordination required for open access requests must be executed via the National Electricity Coordinator.

Exempt Resolution N°154 indicates two types of Open Access Requests (OAR):

− At Public Service Facilities: these correspond to OAR at national and zonal facilities and international interconnection facilities for public service and for development poles. These types of requests are submitted by means of the Request for Connection Solution Approval (RCSA) process.

− For Dedicated System Facilities: these correspond to OAR at dedicated power transmission facilities, in which approval depends on available technical capacity at the facility. This type of request is made by means of a Technical Capacity Usage Request (TCUR).

In order to meet regulatory requirements and ensure appropriate coordination, Transelec has a set of agreements that facilitate coordination between companies (Interconnection AgreementOperating Agreement and Physical Space and Joint Facility Usage Contract).
