Executive Summary

Sri Lanka expects to make the maximum use of renewable energy potential in the country,

with a long-term target of realizing 100% renewable energy by 2050. Solar energy is the

most promising energy source that will contribute towards this. Large-scale solar power

development as solar parks has been introduced by the Ministry of Power and Renewable

Energy as a key initiative in the solar power development programmes. In this approach,

lands that are difficult to be used for agriculture or other economic development activities

are used for solar power generation. Accordingly, the first 100 MW solar park project is

going to be implemented in the Monaragala district. Sri Lanka Sustainable Energy Authority

(SLSEA) and the Ceylon Electricity Board (CEB) are implementing this. The project will be

launched in 2019 and will be completed in 2020. The total estimated cost of the project is

LKR 17 billion. It will deliver 180 GWh of clean energy annually at a 20% plant factor. The

project will reduce the annual fossil fuel imports bill by LKR 56.5 billion during the 20 years

of project life at LKR 19.00/kWh average cost of fuel used for power generation. Further, it

will save 147,542 tons of CO2 throughout the project period, thus leading to support the

Nationally Determined Contributions (NDCs) under the international environmental treaties.

SLSEA, in collaboration with the Forest Department and the Monaragala District Secretariat

have identified land areas of 500 acres for the project. The project location is in 124

Wattegama Grama Niladhari Division in the Siyambalanduwa Divisional Secretariat of the

Monaragala district. It is a shrub jungle belongs to the Forest Department, about 3 km air

distance from Wattegama, about 15 km from the Monaragala town. There are no large

trees available in the particular land areas, and therefore the project can be implemented

with the minimal cutting down of trees. Forest Department has consented for releasing the

land for the project subject to land use committee approval and environmental approval.

Through the implementation of solar parks, it is expected to attract high end investors with

high quality products of latest solar power technologies at competitive rates. So, it will

create direct economic impact to the country. The project will provide information to the

country on implementing large-scale renewable energy parks that will be of high importance

for future projects of the same kind.

1. Background of Power Sector in Sri Lanka

Sri Lanka is a small island of 65,610 km2 land area having a population of 20.95 Million with

a growth rate of 0.9%. As per the energy data of CEB, the peak electricity demand is 2,500

MW and the installed capacity is 4,078 MW. The per capita electricity consumption is 628

kWh with a growth rate of 6%. Total electricity generation in year 2017 was 14,671 GWh.

Country’s national electrification level is almost 100% with 24 hrs uninterrupted electricity

supply, which is a very attractive status compared to the regional situation. Major hydro

power plants, thermal power plants using fuel oil or coal and New Renewable Energy (NRE)

plants using mini hydro resources, solar, wind and biomass are the different types of power

plants catering to the present electricity demand. Details of the existing power plants are

given in Table 01. Power generation facilities for meeting the increasing electricity demand

are implemented according to the Long-Term Generation Expansion Plan of CEB.

Table 01: Details of existing power plants

2. Development of NRE Resources

Sri Lanka has been predominantly dependent on large hydro power plants until 1990s. With

the increase of the electricity demand in the country, fuel oil and coal have been introduced

for the electricity generation mix. With the introduction of mini hydro power plants in 1996,

Sri Lanka initiated the use of NRE sources, and it has surpassed 600 MW in 2018. Expansion

of NRE capacity addition is shown in Figure 02.

Figure 01: Expansion of NRE capacity addition

The initial NRE target was to achieve 10% of the total electricity generation by 2015. It was

successfully realized, where the major contributor was small hydro power projects. Share of

renewable energy (large hydro and NRE sources) in electricity generation in 2016 was 32%,

whereas in a wet year like 2013 the share is 60%. NRE capacity addition for the future

periods has been planned with the vision of realizing Carbon neutrality by 2050. Even

though hydro is the major resource in the overall renewable energy share at present, its

potential for future expansion will be limited as most of the large hydro resources as well as

small hydro resources country in the country have been exhausted. Within this situation,

the major sources identified for future NRE development are solar power and wind power.

Pimarily, these energy sources have high potentials owing to the geographical positioning of

the country, and rapid developments of these energy technologies are taking place at

international level. So, both these facts herald the possibility of using the particular

resources in fairly high potentials towards meeting the future electricity demands. As far as

the solar resource is concerned, as Sri Lanka is located in the equatorial belt, it receives a

year-round supply of solar irradiation. So, many parts of the island have satisfactory solar

resource potentials.

3. Solar Power Development in Sri Lanka

SLSEA published solar atlas in year 2009, and continuous solar irradiation measurements are

being carried out in different parts of the country in order to facilitate large scale solar

power development through availability of comprehensive ground level data on long-term

basis.

Figure 02: Solar Radiation Measuring Station

Page 7: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

There has been gradual development of solar power projects in the country with the

information of solar resource being published. The first intervention for implementation of

projects was made by the Government with the introduction of net-metering concept in

order to facilitate absorption of solar rooftop based power to the national grid. The concept

moved to gain ground in the country after a sluggish start as shown in Figure 03.

Figure 03: Growth of rooftop solar PV market

In September 2016, a crash programme was introduced as Soorya Bala Sangramaya (Battle

for Solar Power) to fast track the solar rooftop programme. Along-with this initiative, the

net-metering scheme was further developed to include two more options, allowing the

customers to get paid for excess energy exported or to export the full generation as a micro

power producer. There have been more than 17,000 roof top projects with a total capacity

of 130 MW by 2018, where a capacity of 100 MW has been installed within the first two

years of implementation of Soorya Bala Sangramaya.

Parallel to the introduction of rooftop concept, a pilot project which utilised KOICA grant aid

was deployed in deep down south with a capacity of 500 kW in 2011. Another plant was

also built under a Japanese grant, adding 737 kW to the national grid in 2012. The first

commercial scale plant with a 10 MW capacity was implemented and commissioned in

December 2016. Today, the grid connected commercial scale projects developed in the

Hambantota and Polonnaruwa districts by the private sector add 50 MW to the national

grid. These projects were developed under a feed-in-tariff of LKR 23.10 per kWh. With the

solar power technologies becoming highly competitive in the international market, solar

power projects are now entertained on competitive bidding process. Solar power projects of

1 MW capacity and 10 MW capacity have been initiated through bidding process,

significantly lower tariffs compared to the prevalent feed-in-tariff have been offered in the

proposals that have been received.

Recognizing the fast development of solar power projects in the country, 400 MW capacity

addition of solar power by 2020 and 1,000 MW by 2025 have been included in the Long

Term Generation Expansion Plan 2018-2037.

4. Recent Trends in Solar Power Development in the World

In the recent decade, the world has seen consistent growth in solar power due to the

advances in technology and its becoming more readily available in different contexts and

applications worldwide. Solar power installation systems totalling more than 97 GW in 2017

took global solar PV power generating capacity to nearly 400 GW, a 32% increase compared

to the previous year. China has the highest cumulative installed capacity of solar power (130

GW), with one-third of the global total. The US (51 GW) and Japan (49 GW) are in second

and third with Germany (42 GW) now in fourth.

Most of solar power development in the world has been achieved through solar park

concept. The Pavagada solar park in India expected to produce 2,000 MW of electricity,

enough to power 700,000 households is the latest milestone in India's transition to

generating more green energy.

Figure 05: Pavagada solar park in India

The Kamuthi solar facility in Tamil Nadu, has a total generation capacity of 648 MW.

Covering 2,500 acres (10 sq km) and consisting of 2.5 million solar panels, the site is

estimated to generate power adequate for 750,000 people. Completed in September 2016

Page 11: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

11

at a cost of approximately US$ 679 million, the station was built in just eight months. The

plant is cleaned every day by a robotic system.

The Longyangxia solar park has a total capacity of 850 MW, sufficient to power 200,000

households. The site sits on the Tibetan Plateau in northwestern China’s Qinghai province,

and is operated by State Power Investment Corporation, one of China’s top five power

generators. Phase I was completed in 2013 and Phase II was completed in 2015, with a total

construction cost of around 6 billion yuan (US$ 920.84 million).

Figure 06: Longyangxia solar park

Kurnool solar park covers 5,932.32 acres (24.0072 sq km) in the Kurnool district, Andhra

Pradesh, with a total generating capacity of 1,000 MW. Construction costs were around US$

1 billion. Over four million solar panels were installed in the park, each with a capacity of

315 W or 320 W. On sunny days, the site is able to generate more than 8 million kWh of

electricity, sufficient to meet virtually the entire electricity demand of the Kurnool district.

The Tengger solar park, located in Zhongwei, Ningxia, is currently the largest PV plant in the

world in terms of both size and production. Dubbed the ‘Great Wall of Solar’, it covers 1,200

Page 12: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

12

km of the 36,700 km Tengger desert, occupying 3.2% of the arid region. The site’s output is

1,547 MW of power.

Figure 07: Tengger solar park

6. Proposed 100 MW Solar Power Park

With the background that solar power has laid a strong foothold in the electricity generation

in the country, it is very important to obtain maximum economic benefits from the

particular resource. Under the solar park concept, project developers are provided with

properly allocated land areas with infrastructure including access roads and transmission

lines, access to amenities like water, initial project requirements like environmental

clearances related to project implementation. Thus, it will create a reduced-risk project for

the investors, whereby it will facilitate attracting renowned solar power development

companies with competitive prices. Accordingly, the new development approach aims at

developing the promising solar resource at a substantially lower cost, reaching grid parity

and with minimum operational impact to the national electricity grid.

Page 13: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

13

The first solar park project is going to be implemented in the Monaragala, with a capacity of

100 MW. The particular solar power capacity has been included in the Long Term

Generation Expansion Plan of the CEB. It has been decided considering the good solar

resources and availability of grid access. It is reported that many grid substations are already

overwhelmed with power produced by renewable energy projects and the system operators

are finding it difficult to accommodate more non-dispatchable embedded generators in the

national grid. The decision to select the Monaragala grid sub-station was made as it is a

relatively easier point to absorb more embedded generators to the particular grid sub-

station.

The project is going to be launched in 2019 and will be completed in 2020. The total

estimated cost of the project is LKR 17 billion.

7. Objectives of the Project

• To add 100 MW of solar power to the National Grid out of 400 MW target by 2020

recommended by the LTEGP 2018–2037

• To get least cost price to a solar park by centralizing 100 MW power park to one

location through making grid substation and other facilities

• To reduce the tariff in competitive bidding process to maximize the economic

benefit to the country

• To reduce CO2 emissions in electricity generation in order to support Green House

Gas (GHG) emission reduction targets under the Nationally Determined

Contributions (NDCs) in the energy sector

8. Project Location

Site Selection

The suitable project site was able to select with the site visit done with presence of

honourable secretary Dr. B.M.S. Batagoda, ministry of power and renewable energy along

with senior officers of forest department and SLSEA on 8th August 2018.

Figure 09: Pictures of the selected site

Page 17: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

17

The area selected is a shrub jungle belongs to the Forest Department. It is a flat non-arable

land situated in a mountain area. So, it is a location which is not possible to be used for

agriculture purposes or for any other economic activities. When selecting the lands,

priorities were given to reduce the number of cutting trees and avoiding the elephant paths.

With the objective of creating the least impact, 10 land blocks (10 MW each) of 50 acres

have been selected. Identified land blocks shown in a GIS map is depicted below. Project

development will be done as 5 Nos. of 20 MW projects combining two adjacent 10 MW

blocks under each. The maps are attached in Annexure 1,2,3 and 4 and more photos are

attached in annexure 5

9. Renewable Energy Potential

The climate in Monaragala is classified as tropical. In Monaragala, the average annual

temperature is 26.3 °C. About 1603 mm of precipitation falls annually. Precipitation is the

lowest in June, with an average of 10 mm. The greatest amount of precipitation occurs in

November, with an average of 289 mm. At an average temperature of 27.4 °C, May is the

hottest month of the year. The lowest average temperatures in the year occur in January,

when it is around 24.6 °C

10. Technical and Organizational

The most efficient solar panels commercially available today have surpassed 20% efficiency,

and this type of efficiency improvement has supported to have high power rating ranges.

Therefore, in order to ensure that the project will have solar panels with high efficiency

ranges, the install power rating range of 300 W – 350 W and power tolerance as +/- 5%.

This will support towards maximizing savings and reduce the payback period of the project.

Further, in order to ensure that temperature increases will make low impacts on electricity

19

generation, panels with less sensitive temperature coefficients will be promoted in the

project. This will be important as many general solar panels may produce 1 percent less

electricity for every 4°F temperature increase above 77°F (25°C), which is the standard

temperature at which tests are performed.

Further, solar panels should be compliant with standards for the manufacturing of solar

cells: ISO 9000 series and Solar panel durability standard IEC 61215, which comply with

International Electro-technical Commission’s (IEC’s) 61215 reliability standard and also

manufacturer’s warranty of preferably 25 years.

13. Project Benefits

The project will deliver 180 GWh of clean energy annually at 18% plant factor and saving of

4.2 LKRB at an average fuel cost of power generation of 19.00 LKR/kWh. The proposed

project will save 147,582 tons of CO2 annually. The proposed approach where the project

infrastructure is developed by the Government and giving opportunity to the private sector

for project implementation will reduce the cost of solar electricity. The lesser cost of solar

electricity will provide a future direction to mainstream solar electricity in the electricity

generation expansion planning.

For the private sector project developers, the proposal will provide a hassle-free investment

opportunity, and an early solution to the present issues resulting from grid constraints. For

local financial services industry, sizable investment opportunities which will enhance their

green credentials, whilst earning them a sound return on investment will be there. Apart

from the financial services industry, other companies who wish to invest in the project too

would enhance their visibility in a sustainability initiative, and will earn good returns on

investments whilst bolstering their CSR efforts and green credentials.

14. Project Design

14.1 Technical Assessment

The concept of this solar power park project is to pre develop and facilitate by the

government sector in order to finance and implement the project by selected privet party

through tendering procedures. It is proposed to develop the infrastructure of the selected

site and get the environmental approval and energy permit and tender 20MW five blocks to

select one or more Privet parties. A one project proponent can develop one block of 20MW

or totally five blocks as 100MW. In this scenario since the tariff, technical details of solar

systems and exact project cost are unknown factors it is difficult to find technical

parameters: No. of panels, no. of inverters and economic parameters project IRR, NPV

sensitivity analysis ect. However, with some assumptions it is expected to give some desing

parameters.

Page 23: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

23

It is expected to fulfil following technical conditions by the project implementing agency

Panel quality

• Efficiency

• Quality

• Ratings

• Performance

• Manufacturer

14.2 Technical parameters to be fulfilled

Solar panel power rating and performance

All solar panels receive a power rating based on the amount of direct current (DC). Ratings

are expressed in watts and represent the power the panel produces under ideal lab

conditions. Most solar panels on the market today have power ratings that range from 200

to 350 watts. The particular project need to install power rating range in 300 – 400 watt In

order to maximize savings and speed up the payback period of the project

As solar panels are manufactured, some unavoidable variations that impact power output

are introduced. Power tolerance indicates how the power output of a solar panel might

differ from its nameplate rating. Typically expressed as a plus-or-minus percentage and solar

panels need the power tolerance as +/= 5%

Solar panel efficiency represents how effectively a solar panel can convert solar radiation

(e.g. sunlight) into electricity. The most efficient solar panels commercially available today

have solar panel efficiency just above 20%.Therefore, recommended solar cell efficiency for

this project is 20% in order to produce more kilowatt-hours of energy per watt of power

capacity

Although solar panels are designed to love the sun, high heat can actually reduce a solar

panel’s capacity to generate power. The temperature coefficient quantifies how a panel’s

power capacity decreases at temperatures higher than 77°F ( 25°C), which is the standard

Page 24: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

24

temperature at which tests are performed. For example, many standard grade solar panels

may produce 1 percent less electricity for every 4°F temperature increase above 77°F.

Panels with less sensitive temperature coefficients will require for the project.

Solar panels should be compliant with standards for the manufacturing of solar cells: ISO

9000 series and Solar panel durability standard IEC 61215 which comply with International

Electro technical Commission’s (IEC’s) 61215 reliability standard in order to evaluates panels

by performing stress tests simulating the decades of outdoor wear and tear that solar

panels encounter during their lifetime. These tests are designed to identify potential

premature failure problems with solar panels, and panels that meet the standard are more

likely to survive in the field. Mean time wind can apply strong pressures to the surface of

solar panels. The higher a solar panel’s wind load ratings, the better it is at tolerating these

forces.

Solar panel manufacturer assurances

Manufacturers’ warranties are an important complement to solar panel efficiency, quality,

and durability metrics, because they indicate both technical specifications and business

practices. In the unlikely event that a solar panel problem occurs post-installation, a strong

warranty ensures that your service and support needs will be covered at least 25-year

power production warranty

The amount of electricity a solar panel can produce declines slightly every year, with the

most significant decline happening in the first year. This is typically referred to as “panel

degradation.” Many solar panel manufacturers provide a power production warranty

guaranteeing that their panels will retain a certain percentage of their production capacity

over the first 25 years, usually no less than 80 percent. For this metric, a higher percentage

guarantee is preferable to a lower percentage. Manufacturers also often provide a specific

guarantee that output will only decline by a certain amount (generally no more than 0.7

percent) in a single year, known as the degradation rate. For this metric, a smaller

percentage is better than a larger one.

Page 25: PRE- FEASIBILITY ON DEVELOPING 100 MW SOLAR POWER …

25

Materials warranty

The materials warranty guarantees against failures due to manufacturing defects, durability,

and environmental issues. Most solar panel manufacturers guarantee that their panels will

not fail for 10 to 12 years, and some extend their materials warranty even further. Make

sure you pay attention to the fine print – some materials warranties will cover the shipping

and labor costs associated with replacing a panel, but others may require you to pay those

expenses.

14.3 Design of the power plants with some assumptions

14. Socio-economic Assessment

The site and surrounding area do not have any settlement and as such, the project does not

involve any displacement of communities. As there will be 100 direct jobs and also indirect

job opportunities through the project, it will support the economic upliftment of the local

population. Further, through electricity generation using indigenous renewable energy

sources, the project will contribute to the overall economic development of the country

through reduction of thermal power generation.

The project will provide much needed clean energy to the South-Eastern region, and will

also improve the infrastructure of the area by way of enhanced electricity supply and

improved roadways. It is envisaged that this inclusive approach will greatly reduce socio-

political barriers which may arise out of the project.
