INTRODUCTION TO THE ENVIRONMENTAL AND SOCIAL

MANAGEMENT PLAN (ESMP) TEMPLATE

Notes:
This Environmental and Social Management Plan (ESMP) template has been created for the purpose
of facilitating the assessment of environmental and social impact factors and the development of
adequate mitigation strategies for prospective mini-grid project developers and operators. The
approval of ESMPs by the applicable regulatory authorities are increasingly becoming a prerequisite
to proceed with the construction of mini-grid projects. This template, thus, is intended to facilitate part
of the project development work.
It is worth noting that the scope of environmental and social mitigation strategies that national
environmental agencies will demand from prospective project proponents are directly dependent on
the regulatory, geographic and demographic context where the future project is to be implemented.
Maximum and minimum threshold limits of, for instance, pollution levels, are not homogeneous
across countries and thus each Proponent must be familiar with the regulatory context where the
project is to be implemented. Nevertheless, clean energy mini-grids per se, regardless of where they
are located, imply a similar set of environmental and social risks, thus enabling the development of
this standardized ESMP template.

Instructions:
This template provides guidance for the preparation and implementation of Environmental and Social
Mitigation Plans. The prospective Project proponent is expected to become familiar with the national
regulatory framework and integrate those parameters of relevance to the template.
To adjust the Template to a specific context, the following is to be considered:
For each missing field, kindly fill in the blank space according to the associated instruction (as
specified in brackets). In some cases, this implies the name of an institution; in others, it implies the
maximum/minimum permitted thresholds as per national regulations.
Kindly attach all relevant environmental legislation under the section Reference

1.) PURPOSE OF AN ESMP

An ESMP is a standalone management tool that details the set of mitigation, monitoring, and
institutional measures to be taken during implementation, operation and decommissioning of a project
to eliminate adverse environmental and social risks and impacts, offset them, or reduce them to
acceptable levels. It is the document produced by the Project Proponent with input of all stakeholders
highlighting the following:
1. identifies potential adverse and beneficial environmental and social impacts of the Project as well
as the extent of short- and long-term effects
2. develops a set of mitigation and enhancement measures to potentially adverse and beneficial
impacts and defines the roles and responsibilities of personnel in charge
3. determines requirements for ensuring that those responses (i.e. mitigations and enhancements) are
made effectively and in a timely manner as well as reported adequately
4. describes the means for meeting those requirements in-line with regulatory/legal basis, if relevant.

3.) ENVIRONMENTAL AND SOCIAL PARAMETERS

In defining the E&S parameters, it is expected that the Proponent will consider the environmental
aspects emanating from the following minimum project activities:
1. Quantities and types of material needed during the construction and operation of the Mini-Grid
Project;
2. Characteristics of the operational process;
3. Physical presence and appearance of completed development within the receiving environment
4. Geographical setting and use of the land for proposed development;
5. Estimated duration of the construction phase, operational phase and where appropriate,
decommissioning phase;
6. Estimated numbers of workers and/or visitors entering the site during construction and operation
and worker camps and/or transportation and access routes;
7. Power evacuation means;
8. Estimates, by type and quantity, of expected residues and emissions (heat, noise, vibration, light,
radiation, air, water, and soil contaminants, etc.) during construction, operation and
decommissioning phases of the proposed Mini-Grid Project;
The environmental and social impact of a Mini-Grid Project will depend to a large extent on the
project’s size (in kW of delivered power), on the project location in relation to its environmental and
demographic context and the mini-grid’s renewable energy fraction. Access to electricity at affordable
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 8

tariffs is to imply direct improvements on the community’s productivity, life comfort, health,
education and possibilities to thrive.
The key power generation components of clean energy mini-grids are solar PV modules organized in
arrays, battery banks (generally relying on lead-acid or lithium-ion batteries) and power electronic
components such as inverters, charge controllers and combiner boxes. Often diesel or petrol generators
are installed to complement the renewable energy components, given the fluctuating nature of
renewable resources such as solar and wind energy as well as overall loads. Battery banks and
inverters, combiner boxes and fuel gensets are located inside a power house. Transformers, low
voltage distribution cables, poles and energy meters compose the power distribution network of a
Mini-Grid Project. The higher the renewable energy fraction of a Mini-Grid, the lower its
environmental impact in terms of air and acoustic pollution during the operational phase; nevertheless,
particular attention ought to be placed on the correct disposal of large battery banks after the Project’s
operational phase comes to an end.
Thus, key environmental impacts to be considered during the ESMP process of a clean energy mini-
grid and their corresponding risk assessment are:

Table 1. Environmental impacts during life-cycle of a clean energy mini-grid

(low probability/medium impact) pollution. Power houses (where gensets are
stored) should be built at sufficient distance
from inhabitants’ houses.

relation to present expenditures on e.g. kerosene/diesel).
Creation of business opportunities.
Access to information (televisions, laptops, internet).
Community gatherings are facilitated during night-hours
as well.
Potential employment of local personnel during the
operation phase.

Increased security Community/streets lighting during the night enforces

security.

Women empowerment Access to electricity is often associated with enabling

women to become entrepreneurs.

Closure/Disposal Phase

Negative health impact Improver disposal of batteries after their life-time can
(low probability/high impact) potentially lead to health risks as described above.

4.) MITIGATION MEASURES

4.1 PV PANELS
Solar modules are the source of conversion from solar energy to renewable electricity. They produce
DC power, which is in turn fed into batteries through charge controllers or fed into the grid after being
converted from DC to AC by inverters. PV panels are made of silicon, metal and glass. The key
components of a PV module are the solar cells (heart of the component), a metal frame (typically
aluminium), glass sheets for casing, wires and steel screws. PV panels are classified as
monocrystalline, polycrystalline or amorphous thin-film modules. Solar panels are known for being an
environmentally-friendly technology, free from noise and air pollution throughout their operational
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 12

phase. For small-scale projects, PV panels are easily integrated into the environment without
fundamentally changing the landscape.
90% of the modules in the market are made of silicon as a semiconductor material. Nevertheless, some
thin-film PV modules use Cadmium Telluride (CdTe). Cadmium is a dangerous and highly poisonous
heavy metal when inhaled or ingested, both for animals and humans, and should be properly disposed
after the Project’s lifetime. Furthermore, the PV manufacturing process is an energy-intensive one, and
priority ought to be given to manufacturers implementing environmental and social mitigation
measures in their processes. Other than the need to properly dispose PV panels as well as rely on
environmentally-conscious PV panel suppliers, no other environmental requirements have to be
fulfilled.
1. Mitigation measures:
a. During construction and operation, no major considerations are required. It is nevertheless
important to keep into account regular PV panel cleaning requirements, for which a
nearby body of water will be necessary. While water access should be ensured, it must
also be properly communicated to the recipient community during early stages of project
design (especially in areas with water scarcity issues).
b. Silicon-based PV panels present little concern during disposal. However, thin-film PV
modules need to be handled carefully. Exposure to heavy metals such as Lead and
Cadmium is a growing problem throughout the world. While the combination of Cadmium
and Tellurium found in some thin-film PV panels reduce the toxicity of the former (with a
concentration of only 0.04% on the entire panel), it is of paramount importance to develop
a proper disposal plan of modules after the end of Project’s lifetime.
c. Emissions from Cadmium and Tellurium are assumed to be close to 0 1. However,
exposure of Cadmium on panels to rain water on landfills can lead to the formation of
leachate in the mid-term. The landfill where PV panels would eventually be disposed of
must ensure the treatment of its effluent. ………………… (kindly state name of country)
environmental regulations set a Cadmium concentration limit on effluents of less than
………… (kindly state maximum level of cadmium concentration levels on effluents as
per national regulations) mg/liter as per ………………… (kindly state source of
applicable national environmental regulation). Minimization of exposure to water of the
modules would
significantly reduce the formation of leachate, and thus minimize the negative
environmental impact in terms of direct soil and water pollution.
d. Furthermore, to minimize potential negative environmental and social impacts of the
entire PV panel value chain from a life-cycle perspective, proper mitigation measures
would include procurement provisions from suppliers regarding recycling and appropriate
precaution practices throughout the manufacturing process. Operators and developers of
mini-grid systems must subscribe to ……………………………… (Kindly state, if
applicable, name of national program regulating end-of-lifecycle equipment disposal).
2. Monitoring of mitigation measures for PV panels:

1
Okkenhaug, et.al., 2010.
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 13

a. In order to ensure the recipient community’s comfort with a developed clean energy Mini-
Grid Project as well as the impact of the PV arrays on the environment, the system
operator should hold meetings with the respective communities periodically to ensure
continued acceptance and comfort with the Project. This is particularly the case when a
scale up of the PV arrays is planned as the community’s load grows.

b. PV panel suppliers ought to be required to provide information on the source/origin of

used raw materials.

4.2 BATTERY BANKS

In combination with the PV arrays, properly sized battery banks allow for a minimization of the
dependence on fuel generators for power supply in Mini-Grid Projects. Mini-Grid batteries are
operational on a daily basis and subject to varying states of charge. For this reason, deep-cycle
industrial batteries are required for off-grid/mini-grid applications, given their high reliability and
lower life-cycle cost to users. While Lead-acid batteries are the most commonly used technology
(mainly due to economic reasons and proven in their application), Lithium-ion batteries are gaining
traction in the market. Although less commonly used, other Nickel-based battery types, such as
Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) batteries, are suitable for remote contexts
with extreme environmental conditions (e.g. high temperatures), given their robustness and long use
life.
1. Mitigation measures for Lead-acid batteries: Besides being heavy components (a single cell can
weigh in the range of 100-200 kg), one of the down-sides of Lead-acid batteries is, as the name
indicates, the presence of significantly more hazardous materials, namely the heavy metal lead
present on the plates and the sulphuric acid. Batteries in mini-grids are generally organized in
several banks, each of which can have a volume of a few m 3 to several m3.
a. During construction, special precaution in the transport and filling of the sulphuric acid
serving as battery electrolyte has to be taken, given its highly corrosive nature. Personnel
dealing with batteries should always wear protective personal equipment such as
protective eyewear and gloves.
b. During operation, battery banks should always be kept in an anti-corrosive container or
sheltered in a well-ventilated room, protected from rain, water and heat. To avoid acid
spillage, a basin should be placed underneath the battery cells.
c. During operation, Lead-acid batteries have to be periodically refilled with distilled water
(a process which should take place only when the batteries are charged and cooled). For
this purpose, personal protective equipment (PPE) such as eyewear and gloves should
always be worn.
d. During disposal, Lead-acid batteries should be transported to specialized collecting points,
given the highly pollutant nature of Lead and as per ………………… (kindly state name
of country) environmental regulations, which set a Lead concentration limit on effluents of
less than …… (kindly state lead concentration limit on effluents as per national
regulations) mg/liter as per ……… (kindly state source of applicable regulation).
2. Mitigation measures for Lithium-ion batteries: Although more expensive, this technology offers a
much higher energy density (thus reducing the total weight of the battery banks) and contains
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 14

significantly less hazardous materials than Lead-acid batteries. The battery cell’s anode is
generally made of Graphite, while the cathode is made of Iron Phosphate, Lithium Cobalt Oxide,
Lithium Manganese Oxide or Lithium Nickel Manganese Cobalt Oxide. While Lithium does not
present any major concerns from the pollution perspective, Cobalt and Manganese are examples of
toxic heavy metals. The electrolyte is comprised of Lithium salt in an organic solution. While
proper recycling of the battery maximizes the use of its components, its relative novelty leads to
limited recycling methods until now.
a. Adhering to IEC’s international safety standards for the selection of Lithium-ion battery
banks as well as their construction and operation should ensure Lithium-ion batteries’
environmental and social impact is independent on the site and thus a more in-depth EIA
would not be needed.
b. If improperly maintained (not kept cooled and regularly exposed to complete discharging)
or are physically damaged, Lithium-ion batteries can be subject to thermal runaway risk,
which involves the rapid expulsion of a toxic gas that can eventually explode if ignited. It
is thus of fundamental importance to keep the battery banks cool and operational as per
manufacturer’s guidelines.
3. Mitigation measures for Nickel-based batteries
a. No major mitigation measures are required during construction and operation.
b. Mitigation strategies for the disposal of Nickel-based batteries will ultimately depend on
the specific compounds present on the battery cells. As previously discussed for PV
panels, the Cadmium present in NiCd batteries is highly poisonous and requires a careful
disposal plan. Alternatively, NiMH batteries can be disposed in properly managed waste
landfills, given their significantly lower composition of poisonous materials.
4. Monitoring of mitigation measures for battery banks
a. Existence/availability of battery recycling points must be ensured. Mini-grid operators
shall subscribe to the ……………………………… (Kindly state, if applicable, name of
national program regulating end-of-lifecycle equipment disposal).
b. Battery manufacturers/suppliers ought to be required to provide information on the
source/origin of used raw materials.
c. Fire alarm systems must be set in place in case of an outbreak of fire due to the battery
banks.

4.3 FUEL GENERATORS

The reliance on properly functioning diesel/petrol generators ensures mini-grid up-time throughout the
day regardless of solar patterns (specially at night and during rainy seasons) while allowing to reduce
initial capital investment in large battery banks and PV arrays. However, these components are the key
contributor to negative environmental and social impacts throughout a Mini-Grid Project’s operational
phase. Gensets contribute to acoustic and air pollution during their operational hours. Furthermore, the
transport of fuel and lubricant oil to remote locations poses in itself an environmental risk, given their
highly hazardous nature. Fuel and oil leakages can significantly affect wildlife and ecosystems by
make drinking water unusable as well as cause injuries and diseases to animals and human beings.
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 15

1. Mitigation measures for fuel generators:

a. Generators have to be regularly and properly maintained/serviced as per manufacturer’s
guidelines to ensure genset emissions are under national emission standards. While
servicing schedules differ across gensets, in-depth maintenance such as air, fuel and oil
filter replacement must generally take place every 250-500 hours of operation. While
genset servicing increases the operational costs of these components significantly (versus
PV panels and battery banks), their negligence substantially increases the environmental
and social impact of generators and shortens the genset’s lifetime. Genset servicing must
be undertaken by certified professionals wearing adequate PPE.
b. Any genset is to be located on a separate and well-ventilated room in relation to the
battery banks. Exhaust pipes should be directed far from PV panel arrays as well as other
electronic equipment.
c. Fuel is an extremely hazardous and flammable material. It must be stored in properly
sealed tanks on-site, at a sufficient distance and separate room from the battery banks. Fire
extinguishers must be available on-site and regularly maintained.
d. A proper fuel refilling mechanism should be ensured (e.g. in the form of manual or
automatic pumps) to pour the fuel from the transport drums to the tank on site, both to
ensure the safety of the responsible personnel as well as avoid spills. Fuel spills must be
cleared.
e. Fuel theft is not uncommon and must be prevented under all circumstances, both for
economic as well as environmental protection reasons.
f. Noise derived from genset operation must remain below ………………… (kindly state
maximum limit of noise pollution levels as per national regulations during day-time) dB
(day-time2) and ………………… (kindly state maximum limit of noise pollution levels
as per national regulations during night-time) dB (night-time) as per
…………………………………… (kindly state name and source of applicable
regulation).
g. The Proponent will adhere to the ……………………………… (Kindly state, if
applicable, name of national program regulating end-of-lifecycle equipment disposal).
2. Monitoring of mitigation measures:
a. The genset and fuel tank room must be kept clean of oil and fuel leakages at all times to
prevent risk of fire.
b. The genset’s operating hours must be constantly tracked to properly and timely plan
servicing schedules. Emissions of SO2, NO2 and particulates must be kept below
………… (kindly stated maximum limit of emitted SO2 as per national regulations) ppm,
………… (kindly stated maximum limit of emitted NO 2 as per national regulations) ppm
and ………… (kindly stated maximum limit of emitted particulates as per national
regulations) mg/m3, respectively, as per national emission standards ……… (kindly state
source of applicable regulation). Emissions must be quantified and reported to
2
Day-time: …………… (kindly state time interval considered to fall during day-time hours as per national
regulations); Night-time: …………… (kindly state time interval considered to fall during day-time hours as per
national regulations).
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 16

……………………… (kindly state name of national environmental regulator, if

applicable).
c. Genset exhaust gas must be colourless.
d. Nearby water bodies ought to be tested periodically to ensure there is no contamination
due to coolants/fuel.
e. Cameras or guards must be based on-site to prevent fuel theft.
f. Measurements on noise levels (both inside the facility as well as within the ambient
environment) must be undertaken periodically with noise level meters and reported to
……………………… (kindly state name of national environmental regulator, if
applicable).

4.4 POWER ELECTRONIC COMPONENTS

Power electronic components comprise those parts of the system controlling the flow of power as well
as converting electricity from one form to another, such as inverters, charge controllers, circuit
breakers, etc. While they imply no significant risk during the construction and operational phase,
heavy metals may be present on their structures and thus disposal on adequately managed
landfills/recycling points is required. As long as the electronic components are installed as per
manufacturers’ recommendations and international standards, these imply very low environmental and
social risk, especially for smaller systems in the range of several kW.
1. Mitigation measures for power electronic components:
a. No special treatment beyond adequate waste management plans is required. Mini-grid
operators shall subscribe to the ……………………………… (Kindly state, if applicable,
name of national program regulating end-of-lifecycle equipment disposal).

4.4.1. MINI-GRID POWER HOUSE, DISTRIBUTION NETWORK AND OVERALL SITE

CONSTRUCTION AND OPERATION
Civil works of mini-grids involve mainly the construction of a power house for the storage of the
battery banks, genset, battery inverters and combiner boxes as well as the erection of poles as part of
the power distribution network. Power houses are constructed on-site next to the PV arrays, all of
which must be gated to prevent theft of any of the components. For small-scale systems of up to 100
kW, power houses are usually not larger than 20 ft. containers, constructed on concrete foundations
and usually covered with metal sheet roofs. In particularly warm climates, power houses may be
equipped with air conditioners that serve as a cooling mechanism for the battery room.
A small-scale mini-grid requires the excavation and erection of several tens or hundreds of poles in
order to connect all customers to the distribution network. Poles are often made of wood, but can also
be made of steel or concrete. The proper excavation of holes for pole erection is of fundamental
importance in order to prevent the risk from poles falling on household structures or other buildings
when subject to strong winds or floods. Furthermore, wooden poles are treated with chemicals during
manufacturing, which can lead to leaching and the formation of surface residues at the right-of-way,
for which proper mitigation measures ought to be taken.
1. Mitigation measures for power house, distribution network and civil works include:
 ES M P G UI DEL I N ES F OR CL EA N M I N I - G RI D P R O J EC T S 17

a. During construction, dug plots/holes must be re-filled after excavation. Hazardous

substances used during construction (such as paint and other chemicals) much be properly
disposed. Construction works must be undertaken in a way to minimize generation of
unnecessary amounts of dust, and noise levels must remain below ……… (kindly state
maximum noise levels during construction activities as per national regulations) dB as per
………………………… (kindly state name and source of applicable national
