The Mexican Federal Electricity Commission (CFE) has released specifications for the construction of a new 1,260 km high voltage direct current (HVDC) transmission line between Yautepec and Ixtepec in southern Mexico. The project will connect wind energy resources to markets in Mexico City. Companies are invited to bid on the construction and 30-year operation of the transmission line, consisting of converter stations, substations, and transmission lines. Payments to the contractor will be fixed charges for capacity and operations/maintenance. The specifications describe technical requirements and development risks that will be the responsibility of the contractor.

► Mexico’s Federal Electricity Commission (Comision Federal de Electricidad or ¨CFE¨) released its
specification of requirements for the construction of a new high voltage direct current (HVDC)
transmission line project.
► The project is consistent with the National Electric System Development Program (PRODESEN),
a 15-year strategic development plan that was released by the Mexican Energy Minister (SENER)
in June, 2016.
► The solicitation invites tenders from companies or duly constituted consortiums for the
construction and operation of a ±500 kV HVDC line running 1,260 kilometers through the Oaxaca
region in southern Mexico. The Project consists of 15 works:
► 2 (two) converter work stations with ±500 kV of voltage – Bipolo, 3000 MW and 5 feaders of Alternating
Current in 400 kV;
► 7 (seven) substation Works with 400 kV of voltage with 1550 MVA of capacity, 150 MVAr and 11 feeders;
► 5 (five) transmission lines Works of Alternating Current with 400 kV of voltage and a total of 438.1 km-C;
and
► 1 (one) transmission line of Direct Current with 500 kV of voltage and a total of 1221.2 km-C.

► The project will provide access to abundant wind resources in southern Mexico, and also satisfy
increasing electricity demand in Mexico City and the surrounding areas.
► The transmission line will connect the Yautepec substation, situated 50 km away from the Mexico
City substation, to the Ixtepec substation, situated approximately 30 km away from the
Tehuantepec substation. The 1,260 km line requires two circuits, with a current rating of 3,000
MVA and a capacity of 3,000MW.
► The CFE tender document describes the requirements and specifications for the construction,
operation, maintenance and transfer (to CFE) of the transmission facilities.

• CFE Transmission is willing to
hedge the incomes it would
receive from CENACE; in this
sense, they may offer indexation
to USD options.
Reasons
• Financing institutions may not
have enough time to provide to
respond with satisfactory financing
conditions.
• Possibility exists that bidders will
not find enough liquidity for MXN
debt for their offers and bidding
full equity would imply strong
exposure to MXN.
• Contacting SWAP for foreign
investors would imply less
competitive bids and may exceed
CFE cap Price.

Methodology
► Real Estate Rights A: CFE will transfer (the ones CFE has; not all) to the Contractor and then to the
Trust. The Contractor is obliged to obtain the missing land rights and transfer them to the Trust.
Contractor must pay a set amount for such rights (not yet defined), it is not clear how such amount is
going to be offset by the rights CFE fails to transfer,
► Real Estate Rights B: the Contractor is obliged to obtain all of these Rights at its cost and transfer
them to the Trust.
Methodology and Findings on Real Estate Rights
Source: CFE & EY analysis
The transfer value of the Real
Estate Rights CFE possesses is not
established.
Transfer Value
Even CFE is flexible in case CFE
does not comply with timeframe for
transferring Real Estate Rights A,
the Contractor would automatically
fail to meet critical milestones of
the Project timeline.

10. Page 10
► Real Estate Rights from CFE: CFE obligated to provide easements. Delays attributable to CFE
provide justification for extending/suspending critical milestone dates. Any delay by the CFE in
transferring the Real State Rights A will only result in an adjustment of the Critical Events Dates, but
in no case will the CFE pay any penalty or adjust the applicable tariff or pay for any costs associated
with such delay.
► Delays associated with securing Real Estate Rights from 3rd parties (not within control of CFE) due
to no fault of Contractor may provide basis for extending critical milestone dates.
► Execution of agreement with CFE means Contractor accepts responsibility for all risks that might
influence construction and achievement of commercial operation date.
► Climatic and hydrological conditions
► Soil characteristics
► Subsoil conditions
► Applicable laws
► Reconfiguration or change in route:
► Contractor must confirm that technical specifications are suitable for construction and implementation of Project
► Contractor can propose adjustments to transmission route to resolve technical or real estate acquisition
problems; however, any adjustments do not permit adjustment to economic offer set forth in the Contract with
CFE.
► Contractor must obtain at its cost, all the Real State Rights arising from any change in the path of the
transmission lines proposed by the Contractor.
► Archeological impacts: any finds must be reported to CFE and appropriate governmental
authorities; any cost impacts or delays are the responsibility of the Contractor.

kV, for three years or more.
 Having managed the O&M within 5
(five) years prior to
the filing of the Offer, made by
another company, Converter Stations
with a voltage equal to or greater than
