At the second edition of Solar Power Mexico, special emphasis will be placed on the different types of energy storage technologies available, as these will play a revolutionary role in the adoption of photovoltaic systems on varying scales, thereby facilitating Mexico’s transition to renewable energies.

Towards a Renewable Energy Transition

1. Mexico is a solar power: Mexico is ideally positioned to make a rapid transition to renewable energies and become a global solar power. Ranked third worldwide in terms of solar irradiation, the country is also home to the world’s largest lithium deposit, has a mature photovoltaic industry and a pool of talented STEM graduates.

2. Advantages of storing energy: The development of energy storage technologies will disrupt the dynamics of the global energy market by doing away with the problem of intermittence, resulting in a more reliable, more diversified electricity grid, mitigating power cuts, reducing prices, and promoting energy self-sufficiency.

a) An industry that is growing exponentially: The sharp decline in the price of storage technologies—driven mainly by improvements in the efficiency of lithium ion batteries and increased consumption of electric vehicles—, coupled with technological progress in the development of materials, components and chemical processes, will lead to the exponential growth of the global energy storage industry in this decade.

b) New market of electricity prosumers: The marriage of photovoltaic and storage technologies will turn users into prosumers, i.e. que consumers who consume the electricity they produce themselves in the same place where it is consumed, which will translate into savings, greater efficiency and the democratization of energy.

C) Reliability and reduced prices: The flexibility afforded by energy storage technologies could help the sector realign periods of supply and demand, resulting in a more reliable, more resilient grid, better quality and lower cost electricity, more profits for users, and greater investment in infrastructure.

d) Paris Agreement goals: Energy storage technologies will be essential to reducing the greenhouse gas emissions associated with transportation and power generation in the short term, enabling us to comply with the 30% reduction in global emissions required to achieve the Paris Agreement goal of keeping the planet’s temperature below 2°C.

3. Energy storage value chain in Mexico: To capitalize on our strategic geographic location and natural resources, we need to create a four-helix platform—government, the private sector, academia and international organizations (GIZ, WEF)—, with a view to setting up a value chain for energy storage technologies in Mexico that will secure our transition to renewable energies and energy independence, and create thousands of well-paid “green jobs” in the process.

4. Smart electricity grid: To ensure our transition to renewable energies is viable on a large scale, we need to promote the creation of a smart electricity grid that is in synch with our new digital reality.

Fortunately, technological breakthroughs in the areas of artificial intelligence, blockchain and big data are producing aggregate solutions and innovative business models in the energy distribution segment.

5. Fusion between Industry 4.0 technologies and electric vehicles: Storage technologies will develop on a par with smart electricity grids, allowing for the creation of a new, renewable system that will power our industries, companies, homes, vehicles and smart devices with clean, unlimited energy.

Mexico and the energy storage value chain

  • Mexico is a solar power: 85% of the country is located within the “solar belt”, which receives annual daily solar irradiation of between 4.4 and 6.3 kWh/m2, meaning Mexico can generate twice as much photovoltaic energy as countries like Germany with the same installed capacity.
  • We are one of the countries best positioned to make the transition to renewable energies. Ranked third worldwide in terms of solar irradiation, Mexico boasts the world’s largest lithium deposit, a mature photovoltaic industry and talented STEM graduates. In other words, we have the capacity to be competitive throughout the entire renewable energies value chain.
  • Due to the low cost of photovoltaic and wind energy in Mexico, storage systems are a means of meeting growing demand for electricity without a proportional hike in prices, while bringing us closer to compliance with the targets stipulated in the Paris Agreement.
  • In the case of countries like Mexico that have competitive component industries, participating in the energy storage value chain opens up attractive opportunities, such as:
    • Creation of jobs in the manufacture, installation and operation of energy storage systems.
    • Development of new industrial structures.
    • Export opportunities for the storage and components industries.
    • R&D to boost the industry’s competitiveness.
    • Reliable electricity supplies.
    • Benefits for other directly related industries, such as electric vehicles, Industry 4.0, software, telecommunications and finances.
  • The de-carbonization of the electricity sector is an unstoppable trend worldwide. Energy efficiency and renewable energies will be the strategic pillars for de-carbonization, particularly in countries like Mexico, whose renewable energy industries have huge potential.
  • Battery storage systems are an interesting alternative for island systems like Baja California Sur, where the grid is powered by expensive, highly polluting fossil fuels that are transported to the peninsula, and systems that are not connected to the central grid, like Yucatán.

The energy storage industry

  • The electricity industry is experiencing a rapid transition. The declining cost of distributed solar generation, combined with commitments to increase the amount of electricity generated from clean sources with a view to reducing pollution caused by power plants, is changing the way electricity is produced.
  • Storage systems will revolutionize the solar energy industry. In the decade ahead, these technologies will grow exponentially and hand-in-hand, resulting in the rapid adoption of solar energy systems of varying scales, the realignment of periods of supply and demand, improved grid reliability, better quality electricity services, reduced prices and new business opportunities.
  • The sharp decline in the cost of storage technologies in the last decade and projections of continued price reductions are driving the adoption of these systems.
  • Energy storage systems are the only technology potentially capable of addressing all the integration challenges associated with electricity generation, such as variability, uncertainty, specific location, non-synchronic nature and the low-capacity factor.
