Environmental Performance

Environmental Management

GRI EN30
GC 8

To prevent and minimize environmental impacts, monitor compliance with legal requirements, and ensure control measures for its environmental aspects, CTEEP has been implementing its Environmental Management System (EMS) at its substations since 2002, based on ABNT NBR ISO Standard 14001:2004.

In 2011, this implementation reached 99 substations and one power line. The EMS involves the five substations in the Regional Maintenance Departments and totals nearly 100% of those owned by CTEEP.

The Company plans to extend the EMS implementation experience to subsidiary company substations and also to expand it to new power lines (PL), considering the lessons learned in the PL 138 kV Araraquara – São Carlos pilot project.

In 2011, the Company invested BRL1.66 million in prevention, management, mitigation and treatment initiatives aimed at preserving and conserving the environment. The 28% reduction in relation to 2010 investments is explained by the large investment required in that year to adapt substations, with the installation of collector boxes and water and oil separators, as well as firewalls.

Consumption of Materials

GRI EN1 GRI EN26
GC 8, 9

Consumption of materials is aligned with CTEEP's commitment, expressed in its Code of Ethics, to rationally use natural resources and respect the environment.

The process of acquiring materials covers technical and economic requirements and involves the quality, environment, occupational health and safety and social responsibility areas. Preventive maintenance interventions on PLs and substations are scheduled throughout the year.

CTEEP uses products that are less aggressive to the environment, such as the epoxy anti-rust paint applied to three substations and seventeen power lines. In addition to protecting substation and line structures against corrosion, this paint creates less environmental impact because of the lower amount of solvent used in its formula.

The process makes maintenance activities more agile, since applying the new paint takes two days, while conventional paint application lasts five days. The process is being used on installations located on the seacoast, where corrosive action is more intense, and on installations in environmental preservation areas. By 2013, another substation and 14 power lines will use this covering.

Recycling and Reuse

GRI EN2
GC 8 9

The Company executes the process of regenerating the insulating mineral oil in its transformers and reactors. Prior to reaching the last stage of its useful life, this insulating oil is regenerated and purified at a mobile regeneration unit, which allows it to regain its original physical and chemical characteristics, enabling its reliable reuse.

For transformers in operation at various Company substations, the mobile regeneration unit carries out the work in an energized regime, in other words, without the need to turn off equipment. Up to 240 thousand liters/month are recycled by the regeneration unit at the oil manipulation station and up to 80 thousand liters/month for energized transformers.

The Company also makes standard use of A4 recyclable paper.

Waste

GRI EN22 EN24
GC 8

CTEEP complies with environmental laws in the transport, handling and disposal of waste, even in cases of waste contaminated by polychlorinated biphenyls (PCBs), classified under Class I (hazardous), posing risks to the environment and human health.

A specialized company licensed by the environmental agency carries out the handling, packing, transport and final disposal of cloth, personal protection equipment, land, sand and insulating mineral oil contaminated with PCBs.

In 2011, 127,166.30 kg of waste was transported and sent for final disposal, of which 65,000 Kg was contaminated material (a 115% increase compared to 2010, due to deactivation and disassembly of two warehouses used for storing contaminated waste) and 62,166.30 kg of lead-acid battery scrap.

All components that make up the batteries are reused by the recycling company contracted (lead, acid and plastic).

Water Resources and Wastewater

GRI EN8, EN10, EN21
GC 8, 9

Water consumption in 2011 was monitored at 47 substations with the Environmental Management System implemented. These substations consumed 37,819 m³ of water. Average water consumption per substation was 13.05% higher in 2011, compared to 2010^(*).

Water consumption and wastewater generated by CTEEP are of the domestic type and are collected via the public sanitation system. The Company maintains a rainwater capture pilot project for washing metal bases (supports) for substation electrical equipment. Variation in consumption in 2010 and 2011 is mostly related to data being collected from more substations, in addition to executing temporary projects and consequently increasing the contingent of people at the substations.

GHG Emissions

GRI EN18
GC 8, 9

Grupo ISA and the Company have prepared initiatives to implement structured monitoring of greenhouse gas emissions. By 2011, the company had only developed R&D projects.

CTEEP adopted a new system of indicators in 2011, supplied by a company specializing in sustainable fleet management.

The new system will allow for monitoring of information such as the total amount of greenhouse gases emitted per kilometer travelled and identification of the vehicles with the highest and lowest rates of emissions.

Performance data will also be monitored, such as vehicle costs per kilometer, supply indicators and a ranking of the most efficient cars. The Company also renewed its fleet of 69 light vehicles and 117 pickups which circulate around the State of São Paulo, to reduce maintenance and fuel costs and increase the degree of safety, comfort and reliability.

Various activities, processes, projects and continual cycles executed in different areas of the Company directly and indirectly promote reduced CO₂ emissions into the atmosphere and, as a result, slow climate change on the planet.

Energy

GRI EN3, EN4, EN5, EN7
GC 8, 9

The energy used at CTEEP substations is from a renewable source (hydroelectric). This energy is obtained from the Company's own transmission system through so-called Auxiliary Service equipment.

In 2011, energy consumption reached 67,099 giga joules. CTEEP has 106 substations, but the energy consumption presented in this Report is in reference to those substations which are monitored for this input. In 2011, considering the "average" consumption per substation, there was a 4.46% increase, compared to 2010.

In situations where normal electric supply was interrupted, the substations used a non-renewable source to re-establish energy, through AEGs (Auxiliary Emergency Groups), powered by diesel fuel. There is currently no routine for registering diesel fuel consumption at CTEEP substations, which rarely enter into operation.

The Electricity Savings Program is among actions developed in 2011, geared towards diminishing the impacts on the environment and improving operational performance. One of the highlights of the program is the changing of incandescent light bulbs for LED lights on synoptic panels, used to indicate whether substation equipment is on or off. In addition to less energy expenditures, this light bulb is more durable. In 2011, CTEEP saved 2,010.71 gigajoules.

Control of Noise Pollution

GRI EN26
GC 8, 9

CTEEP is also aware of the impact of noise on the area surrounding substations. Whenever transformers need to be installed in highly residential regions, CTEEP designs its equipment for noise levels compatible with the location, even if this results in higher costs.

To minimize these impacts, CTEEP has implemented two measures in at least three substations. One is related to acoustic barriers and another is related to technical specifications.

SE Centro

CTEEP placed an acoustic barrier around the perimeter of the transformer installed at position TR3, confining not only the noise of normal operation, but also of the forced cooling fans when they begin to operate.

SE Miguel Reale

The 345 kV and 132 MVA reactor bank was confined to a masonry structure to contain noise. This solution required conceptualization of an exhaust system capable of withdrawing the hot air from inside the structure to cool the reactors.

SE Anhanguera

At this substation, the transformers were already designed with the maximum acceptable noise level, measured according to ABNT (Brazilian Association of Technical Standards) criteria at 65 decibels at one meter from the transformer. Because the level of noise decreases with the square of the distance and the materials that comprise the soil and structures, residents close to the substation expect something around 40 decibels, within the zone of acoustic comfort.

Biodiversity

GRI EN11, EN12, EU13

Currently, all of the environmental protection areas through which the Company's power lines pass are mapped. However, CTEEP does not have data on the state of conservation of these areas, considering the IUCN (International Union for the Conservation of Nature and Natural Resources) classification.

In every undertaking where there is a need to suppress vegetation, CTEEP carries out off-setting planting to comply with the determination of the licensing environmental agency through the Term of Commitment to Environmental Recovery (TCRA). With this goal, the Company contracts and monitors companies specialized in executing and maintaining these plantings. Furthermore, studies are done to assess the interference of power lines with the local fauna in order to minimize or mitigate any resulting impact.

In 2011, CTEEP finalized reforestation of 239.39 hectares of Forest Institute areas (remaining area of 33 hectares, according to the Term of Adjustment of Operating License Conduct 0136).

Planting is underway on three hectares next to the Jupiá dam (TCRA), planting of 1.82 hectares in the 345 kV BSA-SUL Power Line band (authorized for intervention in PPA - Permanent Preservation Area) and planting of 0.345 hectares in the area adjacent to the CAV Substation (TCRA).

In an effort to ensure protection or restore different habitat areas other than those supervised by CTEEP, a partnership was established with Instituto Guatambu de Cultura (Guatambu Culture Institute) in the area surrounding the Anhanguera-Guarulhos PL, in the Cantareira State Park.

In total, the Company accounts for 2.723 km² of protected and/or restored habitat areas. To ensure efficacy in all compensatory activities, CTEEP relies on monitoring and approval by external specialists from the FEALQ (Luiz de Queiroz School of Agricultural Engineering).

Compliance with Laws and Regulations

GRI EN28

All environmental management activities, proper disposal of waste, treatment of wastewater and environmental restoration are done pursuant to current environmental law.

In 2011, CTEEP did not receive any significant fines and/or non-monetary sanctions and it was also not included in any arbitration processes regarding environmental matters.

Throughout the year, CTEEP received some notifications for clarification and measures on various environmental issues, which did not result in punishment of the Company.

In 2011, the Company had not been notified of any decision regarding administrative processes from 2010:

1) Notice of Violation No. 11,491 from the São Paulo City Hall, in the amount of BRL322,500.00, related to the practice of sacking earth carried out by a trespasser on CTEEP property. The Company presented an administrative defense in 2010.

2) Notice of Violation No. 027,241 A from the Ministry of Environment – ICBIO, in the amount of BRL1,000.00, regarding suppression of vegetation in an environmental preservation area, between the cities of Matão and Cosmópolis (SP). In 2010, CTEEP presented an administrative defense because it had done conservation work in the right of way for the power line.

Main Projects

GC 8

Burn Prevention Campaign
GRI EN14

Every year, CTEEP holds a Burn Prevention Campaign, whose goal is to raise awareness among stakeholders (plants, rural workers, farmers, society and employees) about the risks of the practice of burning in areas close to electrical power lines.

Through a publicity campaign and initiatives to build closer relationships with communities, this project is aimed at educating the population in the communities surrounding the transmission towers, in addition to contributing to cutting CO₂ emissions. In 2011, the Company invested BRL391,880.00 in the tenth edition of the campaign, directed at the regions of Andradina, Limeira, Lins and Sandovalina, selected because of their history of problems with burns.

The 2011 campaign also covered the use of harvesters, which have been replacing fire in the removal of unused sugarcane. When used close to tower and cable structures, these machines can cause serious accidents and interrupt the supply of power.

CTEEP employees play a fundamental role in the campaign, distributing material and spreading information. The campaign has garnered effective results. In 2011, the events related to burns caused shutdowns to drop by 61% and occurrences to fall by 55% compared to 2010.

Green Shield

GRI EN26
GC 8, 9

CTEEP developed an R&D project to replace vegetation in Permanent Preservation Areas (PPA) through which its power lines pass. The project uses the "green shield" technique, which consists of replacing large native vegetation with other, smaller vegetation that does not present a risk to power lines.

Among the benefits of the project is environmental conservation, protection of power lines, reduced trimming and mowing and lower monitoring costs. The project has been applied to planting done in Botucatu and Jarinu, in the interior of the State of São Paulo.

A digital map of the lines in the state's interior is being created, with the location and size of rural areas, unsuitable for agricultural use, which could also house the project. Moreover, the Company has prepared a technical manual of recommendations of plant species for PPAs (Permanent Preservation Areas).

Cuca Project

CTEEP also supports the Cuca Project environmental education program, developed by Cantareira State Park (SP) in partnership with the Instituto Guatambu NGO. The program is one of the conditions for licensing of the Guarulhos-Anhanguera Power Line.

The project includes activities for student groups and the surrounding community inside and outside of the environmental conservation unit, focusing on combating illegal disposal of waste, predatory hunting of wildlife, fires, trespassing, etc., in addition to holding talks to raise awareness and on citizenship, preservation of biodiversity and power lines. In 2011, project activities reached a public of 14 thousand people.

Urban Orchard

CTEEP was one of the first companies to adhere to the Urban Orchard project in 2000. In partnership with the São Paulo State Government, the Urban Orchard promotes environmental and landscape recovery along the banks of the Pinheiros River, professional training and environmental education.
