Regulation

Law 1715 of 2014

Regulation for large-scale self-generation connected to National Interconnected System (SIN) in Colombia. This CREG Regulation establishes the following articles: - The connection to the SIN must follow the CREG Resolutions 106/2006, 070/1998 and 025/1995 and 156/2011 - Measurement system: CREG Resolution 038/2014 - Commercial frontiers: CREG Resolution 157/2011 - Conditions for the access to the network backup: CREG Resolution 097/2008 - Energy supply: through a energy marketer (no as a regulated client) - Reliability charge: CREG Resolutions 071/2006 and 063/2010 - Other costs: CREG Resolutions 024 and 025/1995 - Large scale limit: according to Resolution 281/2015 the limit is 1 MW Surplus delivery: - If the maximum declared power is higher than 20 MW, then No Centrally Dispatched Plant conditions applied. - If it is lower than 20 MW, Centrally Dispatched Plant conditions applied (The National Dispatch Centre or CND, is responsible for the planning, control and supervision of the integrated operations of energy generation, transmission and interconnection of the SIN).

Energy policy guidelines for delivery of self-generation surplus which establish the following articles: - Symmetry between electricity generators and large-scale self-generators in the Colombian wholesale market to sale electricity - Large-scale self-generators must sign a support contract with the network operator - Large scale limit: according to Resolution 281/2015 the limit is 1 MW The parameters required to be considered self-generator are the following: - Electricity production to be consumed by their own use, without using any National Transmission System and/or distribution system assets - The surplus can be higher in any percentage than the consumption needs - Follow regulations from the Comisión de Regulación de Energía y Gas (CREG)

Regulation and specifications for cogeneration in Colombia: - Requirements and technical conditions to be considered a cogeneration process and definition of the Equivalent Electric Performance (REE) - Minimum values for REE - Measurement systems definition - Measurement report (Electrical energy, useful heat and primary energy) - Audits and tests definition (CREG 047/2011) - Requirements and conditions for cogeneration units, defined by National Dispatch Centre (CND) - Support energy remuneration specifications (CREG 097/2008) Surplus delivery with power guarantee: - If the power guarantee is lower than 20 MW: Option 1: No Central Dispatch access -> no stock market participation -> "No Centrally Dispatched Minor plants regulation" applies Option 2: Central Dispatch access -> stock market -> Regulation "inflexible" generators - If it is higher than 20 MW: Central Dispatch access -> stock market -> Regulation "inflexible" generators Surplus delivery without power guarantee: Option 1: No Central Dispatch access -> no stock market participation -> Non-regulated users Option 2: Central Dispatch access -> stock market -> Regulation "inflexible" generators (The CND, is responsible for the planning, control and supervision of the integrated operations of energy generation, transmission and interconnection of the National Interconnected System (SIN)).

Regulation for compulsory audits and tests for cogeneration systems: The user who want to be considered as a cogenerator by the CREG, must hire an authorized company to audit the cogeneration system, according to the following procedure: Phase 1: Documentation review (according to the numeral 6 of Annex 1) - Deviation list from the procedure of Annex 1 - Concept: is it possible to do the audit according to Annex 1? Phase 2: Audit and tests in-situ - All the deviations over the standard parameters (from Phase 1) must have been corrected - Main outputs: Equivalent Electric Performance (REE) and if the correction methodology used by final user allows the application of Article 7 of CREG Resolution 005/2010 for this test The Annex attached to this Resolution (Annex 1) details all the methodology to do the tests and calculates the required outputs. It defines the following issues: - Technologies and cycle types - Units of measurement and equivalences - Measurement procedures - Documentation from cogenerator for Phase 1 - Methodology for the tests – Forms
