Detailed Technical Description of HHGM's EPC Services and Energy Solutions

EPC

At HHGM, we understand that modern electrical infrastructure requires reliable, efficient solutions with the highest technical standard. That's why we introduced EPC (Engineering, Procurement & Construction), our comprehensive service that accompanies the entire cycle of electrical generation, transmission and distribution projects.

With EPC, we offer:

• Specialized engineering: From conceptual design to executive plans, ensuring regulatory compliance, resource optimization and solutions adapted to the local context.
• Strategic Sourcing: We select the highest quality materials and equipment, with certified suppliers, to ensure efficiency, durability and operational compatibility.
• Construction and start-up: We are responsible for civil execution, electrical and mechanical assembly, testing, interconnection and start-up, with professional supervision and rigorous safety standards. As well as the necessary paperwork for the proper operation of the projects.

Why choose the HHGM EPC?

Turnkey solution

point-to-point solution, we reduce risks, delivery times and administrative complications, allowing you to focus on what matters most: your energy goals.

Proven experience

HHGM has a solid track record in electrical projects in Mexico — generation, transmission and distribution — which supports our technical and operational capacity.

Regulatory and Regulatory Compliance

We ensure that we comply with all applicable national and international standards, including the requirements of, CFE, CENACE and other regulatory entities.

Optimization of costs and times

Thanks to efficient engineering, purchasing and construction management, we minimize delays and cost overruns. Our comprehensive approach allows us to anticipate problems and maximize resources.

Quality and safety as a priority

Each stage of the project is governed by strict quality control, industrial safety and environmental responsibility protocols.

If you are planning an electrical project and are looking for a reliable, professional partner with the capacity to take your vision from idea to implementation, our HHGM EPC service is the ideal choice

EPC: Solar

At HHGM, we take solar energy to the next level with our comprehensive turnkey service (EPC). We take care of the entire process — from engineering and design, to equipment supply, installation, start-up and regulatory management without investment from our customers — so that your photovoltaic project is safe, profitable and efficient.

We offer turnkey solutions adapted to the needs of each client, with three main generation and financing schemes:

Generation with Net Metering

Offset your electricity consumption by injecting the energy generated by your photovoltaic plant into the grid. Under this model, we offer two schemes:

Total Direct Purchase

The customer purchases the entire plant and obtains the immediate benefit of saving on their electricity bill.

Main benefit: full ownership of the asset and reduced operating costs from day one.

Power Purchase Agreement (PPA) Scheme‍

HH GM makes 100% of the investment necessary for the installation and implementation of the plant, as a result, the customer reduces energy consumption that is transferred to direct savings, with this savings the customer pays for the energy it generates at a lower and more stable price than that of the CFE.

• Main benefit: zero initial investment, immediate savings and long-term energy cost security.

Why choose HHGM's EPC Solar?

• Optimized design: maximization of energy generation and return on investment.
• Reliable supply: we work with leading manufacturers of modules, inverters and structures (TIER 1 PREMIUM).
• Certified installation: specialized equipment and strict compliance with national and international regulations.
• Regulatory Management: we take care of the necessary procedures and permissions to interconnect and operate your plant.
• Tailor-made model: we choose with you the scheme that best suits your financial and energy objectives.

At HHGM, we make solar energy a safe and strategic investment, whether it's to save, insure your energy cost or generate income in the electricity market.
