Clean Products The Grid Solutions product and service approach aims at improving
environmental performance of its industrial offer. It means minimizing
environmental impacts on all phases of the product life cycle: sourcing,
manufacturing, transport, use, and end of life.

Clean Products

Developing sustainable products is at the heart of the Grid Solutions business model,
which includes multiple initiatives covering different focus areas.

Eco Design

Since the 2000s, GE’s Grid Solutions has embarked on the path of eco-design – integrating the environment into the design phase alongside other conventional design concerns such as customers’ expectations, technical performances, cost control, etc.

The objective of Grid Solutions is to reduce the global environmental impact of its products, over its whole life cycle, from the extraction of the raw materials until the end-of-life, while considering all environmental indicators.

Eco-design is one of the pillars of Grid Solution’s Clean Grid program.

The process put in place is following IEC 62430 “Environmentally conscious design for electrical and electronic products” recommendations. The target is to introduce environmental requirements as far upstream as possible in the design process, i.e at the start of the product development, in order to reduce its global environmental impact compared to the product that is replaced.

Product Environmental Profile

Product Environmental Profile (PEP), also known as Environmental Product declaration (EPD), is a document for customers communicating the environmental impact and performance of the product. It is the environmental ID card of the product.

A PEP includes several sections:

  • Description of the product studied and technical performance
  • Description of assumptions used for each life cycle phase
  • Life cycle assessment (LCA) results on 18 environmental indicators
  • Environmental advantages of the products

The PEP is based on Life Cycle Assessment. More than 70 Product Environmental Profiles are available so far, covering:

  • Gas-Insulated Substations
  • Live tank circuit-breakers
  • Dead tank circuit-breakers
  • Generator circuit-breakers
  • Air-insulated disconnectors
  • Instrument transformers
  • Transformers
  • HVDC valves
  • Automations products

GE Product environment profiles are periodically updated with new data and new products. You can access the complete list of available PEP.

Life Cycle Assessment

Life Cycle Assessment (LCA) is a quantitative methodology ruled by international ISO 14040/14044 standards. LCAs are commonly used to map and evaluate the environmental impact of products or activities along their life cycle.

  • Manufacturing phase: materials, energy consumption, emissions, waste…
  • Distribution phase: packaging & transportation
  • Use phase: power consumptions, emissions, maintenance, fluid leakage…
  • End of life: dismantling, material treatments

A LCA considers all the environmental indicators: pollution of water, air, soil and the depletion of resources. The study presents the environmental impact of the product not only on climate change (carbon footprint), but also ozone depletion, water acidification, toxicity, and impact on resource depletion.

Circular Economy

Circular performance of Grid Solutions' high-voltage products is the following:

EFFECTIVE USE OF RESOURCES:
  • Material mass reduced compared to previous generation
  • Optimum use of scarce materials
MAXIMIZED LIFETIME:
  • Product with long lifetime thanks to reliable design
  • Easy maintenance and repair, services offered
OPTIMIZED END OF LIFE:
  • Products with high recyclability rates
  • Mass of non-recyclable materials reduced to the maximum
  • No hazardous substances (RoHS voluntary compliance)
  • End of life instructions for recycling optimization
  • End of life recovery service
REDUCED ENVIRONMENTAL IMPACT:
  • Use of new innovative materials like g³ in replacement of SF₆
  • Assessment of the environmental impact of products through LCA (Life cycle assessment) methodology of ISO 14040. Communication to the customer of the product environmental performance though PEP (Product Environmental Profiles).

Clean Services

To support customers growing environmental challenges, Grid Solutions provides a variety of services to increase efficiency, reliability and environmentalism of customer assets. Grid Solutions helps customers to reduce power consumption, greenhouse gas emissions and material consumption, and to use ecological and sustainable solutions especially in the recycling process. By supporting customers in SF₆ management and offering different end-of-life options, Grid Solutions is the ideal partner to better manage equipment through its lifecycle.

Grid Solutions provides a number of green services, including SF₆ management (handling training and certification, leak detection and repair), optimizing transformer eco-performance (vegetable oil, monitoring, oil analysis), and end-of-life management (decommissioning, refurbishing).

Many regulators now request that grid operators manage the end-of-life of their equipment with the lowest environmental impact. Grid Solutions supports customers by providing end-of-life management services:

  • Equipment decommissioning, refurbishing and recycling, with a focus on reducing industrial waste, reusing a maximum number of parts, reducing SF₆ emissions and complying with environmental and safety conditions
  • SF₆ recycling, including the recovery of contaminated SF₆ (mix of SF₆ with other gases) contained within products to prevent any release of SF₆ into the atmosphere and to recycle or reuse SF₆
G3 substation

Grid Solutions is committed to transferring knowledge and technical expertise to its customers. The Technical Institute Aix-les-Bains(TIA) has been accredited by the French government to evaluate and certify workers from across the industry involved in recovering SF₆ sub gas from high and medium voltage switchgear. TIA offers two different training programs relating to the use of SF₆ gases and adapted to applicant experience.

The International Electrotechnical Commission (IEC) has edited a new standard, ref. IEC 62271-4, regarding SF₆ gas handling on all electric power equipment. The Technical Institute Aix-les-Bains offers to train and certify your team on this new standard.

The training center supplements the practical examination with hands-on training, on real equipment, including gas-insulated switchgear and air-insulated switchgear technology.

In addition, the Technical Institute Aix-les-Bains can address other international regulations and standards related to SF₆ handling, for internal and external operators from worldwide electrical industries.
