Environmental Impacts of Renewable Energy Technologies


Renewable Energy—wind, solar, geothermal, hydroelectric, and biomass—provides substantial benefits for our climate, our health, and our economy.


All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.


However, renewable sources such as wind, solar, geothermal, biomass, and hydro-power also have environmental impacts, some of which are significant.


The exact type and intensity of environmental impacts varies depending on the specific technology used, the geographic location, and a number of other factors. By understanding the current and  potential environmental issues associated with each renewable energy source, we can takes steps to effectively avoid or minimize these impacts as they become a larger portion of our electric supply.



Environmental Impacts of Wind Power

Wind power generates electricity without toxic pollution or global warming emissions, but it does have some environmental impacts that should be recognized and mitigated.


Wind power

Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions. Wind is also abundant, inexhaustible, and affordable, which makes it a viable and large-scale alternative to fossil fuels.


Despite its vast potential, there are a variety of environmental impacts associated with wind power generation that should be recognized and mitigated. They include land use issues and challenges to wildlife and habitat.

Environmental Impact of Solar Power

The potential environmental impacts associated with solar power depend on the technology, which includes two broad categories: photovoltaic solar cells and concentrating solar thermal plants.

Solar Panel

Like wind power, the sun provides a tremendous resource for generating clean and sustainable electricity.


The environmental impacts associated with solar power can include land use and habitat loss, water use, and the use of hazardous materials in manufacturing, though the types of impacts vary greatly depending on the scale of the system and the technology used—photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).

Environmental Impact of Geothermal Energy

Geothermal grows in Kenya



The most widely developed type of geothermal power plant (known as hydrothermal plants) are located near geologic “hot spots” where hot molten rock is close to the earth’s crust and produces hot water.


In other regions enhanced geothermal systems (or hot dry rock geothermal), which involve drilling into the earth’s surface to reach deeper geothermal resources, can allow broader access to geothermal energy.


Geothermal plants also differ in terms of the technology they use to convert the resource to electricity (direct steam, flash, or binary) and the type of cooling technology they use (water-cooled and air-cooled). Environmental impacts differ depending on the conversion and cooling technology used.


Environmental Impacts of Hydroelectric Power 

Hydroelectric power includes both massive hydroelectric dams and small run-of-the-river plants, both of which have associated environmental impacts.


Hydroelectric power

Hydroelectric power includes both massive hydroelectric dams and small run-of-the-river plants. Large-scale hydroelectric dams continue to be built in many parts of the world,but it is unlikely that new facilities will be added to the existing Africa fleet in the future.

Instead, the future of hydroelectric power in Africa will likely involve increased capacity at current dams and new run-of-the-river projects. There are environmental impacts at both types of plants.


Environmental impacts of Hydro-kinetic energy

Tidal flow

Hydrokinetic energy includes wave and tidal power and encompasses an array of energy technologies, many of which are still in the experimental stages or in the early stages of deployment.


Hydrokinetic energy;

Hydrokinetic energy, which includes wave and tidal power, encompasses an array of energy technologies, many of which still in the experimental stages or in the early stages of deployment. While actual impacts of large-scale operations have not been observed, a range of potential impacts can be projected.

Despite these environmental impacts, renewable energy technologies compare extremely favorably to fossil fuels, and remain a core part of the solution of climate change.

Renewable Energy

Solar Panel

Renewable Energy is energy that is collected from renewable resource, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.


Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.


Nigeria has enormous solar energy potential, with fairly distributed solar radiation averaging 19.8 MJm2/day and average sunshine hours of 6h/day. The assumed potential for concentrated solar power and photovoltaic generation is around 427,000 MW.


According to estimates, the designation of only 5% of suitable land in central and northern Nigeria for solar thermal would provide a theoretical generation capacity of 42,700 MW.


SOLAR RADIATIONS: Solar energy is also one of the oldest renewable energy sources in the world. This energy is taken from the sun in the form of solar radiation. There are basically three ways that we can use the sun’s energy;

  • Solar cells in which photovoltaic or photoelectric cells are used to convert light directly into electricity.
  • Solar water heating in which the heat from the sun is used to warm the water in glass panels of solar energy system therefore no longer requiring gas or electricity to heat the water.
  • Furnaces that use mirrors to capture the sun’s energy into a concentrated place to produce high temperatures.

Stable Energy Prices

Renewable energy is providing affordable electricity across the country right now, and can help stabilize energy prices in the future.


Although renewable facilities require upfront investments to build, they can then operate at very low cost (for most clean energy technologies, the “fuel” is free). As a result, renewable energy prices can be very stable over time.


Moreover, the costs of renewable energy technologies have declined steadily, and are projected to drop even more. For example, the average price to install solar dropped more than 70 percent between 2010 and 2017. The cost of generating electricity from wind dropped 66 percent between 2009 and 2016. Costs will likely decline even further as markets mature and companies increasingly take advantage of economies of scale.


In contrast, fossil fuel prices can vary dramatically and are prone to substantial price swings.


Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. And an increased reliance on renewable energy can help protect consumers when fossil fuel prices spike and the Climate.


Needless to say, the intrinsic benefits of Renewable Energy is greatly untapped, which is why, at RS Engineering Global Limited, we are in business to develop and operates utility-scale solar PV projects for the wholesale and retail market in Africa. The Company also provides operation and maintenance (O&M) services for investor/owners.



We believe solar makes the world cleaner and healthier. Our team successfully develops, builds and operates solar facilities across Africa.”

What You Should Know About Preventive Maintenance

Companies large and small, and across all industry, service and corporate sectors, rely on efficient functioning of equipment in order to operate and be profitable. When a piece of equipment breaks down or fails, operations are impeded and can impact a company’s bottom line. Until recent years, the approach to maintenance tended to be reactive; in other words, taking care of problems as they arose. While there may be some short-term gains to this approach, the costs of operation shutdowns as well as replacing (rather than repairing) equipment over time tend to be much higher. One way for businesses to overcome unforeseen and costly repairs is putting in place a preventative maintenance program for all its assets. Preventative maintenance (PM) is performed while the equipment is still working so that it does not break down unexpectedly. While a growing number of companies are moving toward Computerized Maintenance Management Software (CMMS) systems, others rely upon spreadsheets to monitor the status and upkeep of their equipment.


Before establishing a preventative maintenance (PM) program, the following steps should be followed:

1. Gather information on equipment

Data entry of the equipment

A starting point in any preventative maintenance program is becoming familiar with company’s equipment. It is important to document the make, model and serials numbers of each piece of equipment along with maintenance guidelines and specifics on installations, repairs and parts replacement.


2. Develop a baseline on equipment usage

To gauge the functioning of a piece of equipment, it is important to establish machine downtime, meantime-between-failure (i.e., amount of time between repairs), the cost of parts replacement, the amount of time spent by technicians, the technician’s response time and percentage of parts deliveries made on time. From this information, it is possible to calculate the average cost of one hour of downtime and thus form a baseline from which a PM preventive maintenance program can be evaluated.


Once the above information has been gathered, the outlines the best practices to follow when instituting a preventative maintenance program:

1. Plan an efficient preventative maintenance program

It is important to take a realistic approach to PM preventive maintenance. The allocated technician time should be based on the size of the company and the number of pieces of equipment to be maintained. Once this variable is determined then a PM preventative maintenance plan can begin to be budgeted for.


2. Consider if a Computerized Maintenance Management Software (CMMS) system is appropriate

While maintenance management software are costly in terms of upfront costs and/or subscriber fees, they are sophisticated and robust systems that utilize thousands of data points and at any given time, can provide a user with an overview of a facility’s operation or alternatively, the status of an individual piece of equipment. These systems have the ability to monitor inventory levels, track work orders, quickly generate accurate reports, and instantly determine which of their assets required preventive maintenance. When factored against manually monitoring all these variables and functions, a CMMS software may increase technician response time, which in turn lowers the mean time to repair and reduces the amount of downtime. Maintenance management software may be a more viable solution for many companies.


3. Have supplies and parts on hand

In executing a PM preventive maintenance program, it is important to have supplies and parts on hand to avoid unnecessary downtime. By ordering in advance, companies may be able to take advantage of discounts that may not be available when supplies and parts are purchased on an urgent basis.


4. Establish PM preventative maintenance checklists

Checklist logger

Equipment often has specific maintenance protocols to be followed. Establishing task checklists in advance help to estimate the amount of time needed to maintain a particular piece of equipment.


5. Develop an efficient preventative maintenance schedule

Since some pieces of equipment need to be maintained more often than others, examine the information gathered previously to guide the frequency with which servicing needs to be conducted. Based on the findings, then technician time can be allocated. As well, for large operations, preventive maintenance can be carried out based on the location of several pieces needing servicing at the same time. This type of coordination is more cost saving and more efficient than deploying technicians to conduct maintenance in different areas of a facility.


6. Select trained technicians

Equipment only will operate as efficiently as those who use and service it. Therefore, it makes most sense to select technicians with the necessary skills to maintain specific company assets. For small operations, it may be more cost effective to use third party technicians rather than hire in-house service providers. By having several pieces of equipment serviced at once utilizing a preventative maintenance program, makes subcontracting servicing an optimal choice.


7. Monitor costs and performance, and adjust as needed

Taking stock of spare parts cost and performance cycle

Once in place for several months, companies should monitor their PM preventive maintenance programs by evaluating associated cost/benefit effects. Results may vary depending on conditions or changes within the company’s activities. Maintenance managers can adjust PMs as needed with an eye toward increasing overall operations efficiency.


The shift from reactive maintenance and toward preventative maintenance is seen as beneficial for many companies whose operations are highly dependent on reliable equipment functioning. The benefits of preventative maintenance software include: uninterrupted manufacturing runs by eliminating machine breakdowns, increased product quality as well as decreased capital expenditures by increasing machine lifespans and reducing spare parts costs.

Preventive maintenance is defined as regularly scheduled inspections, tests, servicing, replacements, repairs and other tasks intended to help reduce the impact and frequency of equipment failures. This includes scheduled preventive maintenance, predictive maintenance and inspection activities.

The objectives of a preventive maintenance program are to help:

1. Identify maintenance actions on important equipment and incorporate that into the preventive maintenance program activities that result in the greatest benefit within the available budget.


2. Minimize corrective and breakdown maintenance, maintain satisfactory equipment conditions and improve plant reliability


3. A preventive maintenance program should be well defined, periodically reviewed and adjusted as necessary. To help ensure proper implementation, procedures should be written in sufficient detail for each piece of equipment in the program.



Machine don’t die,they are murder by quacks ,Which why, RS Engineering Global Limited is poised to delivering Quality but cost effective services to you.





No one wants to get hurt, but sometimes we neglect best safety practices because it takes extra time and effort, a little extra time is always worth it to avoid an injury.

Checking workplace safety throughout the day is an easy way to keep your working environment safe.

If you are a supervisor, it shows your employees that you care about them and their well-being. It takes leadership to improve safety.”

Being safety oriented can help improve your employees’ morale, productivity, and even make a good impression on visitors.

If you are an employee, following safety protocols are in your and your coworkers’ best interests.

We’ve got 10 good tips for keeping you and other people safe at work below.

Give them a quick review and we hope they help to keep you safe and healthy.


1. Inform Supervisors of Unsafe Conditions:

If you see something that could potentially hurt someone, remove the object or clean the area if you can do so safely. Otherwise, inform your supervisor. Since your supervisor is legally obligated to keep you and your fellow employees’ working environment safe, they must take action.


2. Use Equipment, Machines, and Tools Properly:

Misusing tools and machines is the most prevalent cause of workplace injuries. When using equipment, make sure that you are using each piece of equipment for its intended purpose and are using it correctly. Furthermore, regularly clean and inspect equipment to ensure that it is safe.


3. Wear Safety Equipment (PPEs):

When cleaning up messes and using equipment, make sure you wear the proper safety equipment. Making sure you wear the proper safety equipment and checking that your safety equipment is undamaged significantly lowers your likelihood of getting injured.

However,wearing these PPEs correctly is very Imperative too.


4. Prevent Slips and Trips:

As the second most prevalent cause of nonfatal occupational injuries, it is vital to ensure that aisles are clear and spills are cleaned to prevent employees from tripping or slipping. If you are dealing with a liquid, use drip pans and guards. Clean up any spills immediately to keep conditions safe. Also, check your workplace to make sure there are no holes, loose boards, or nails projecting from the floor. If any of these characteristics exist, replace the damaged flooring. In areas that cannot easily be cleaned, consider installing anti-slip flooring.

Few checklist to prevent Slips and Trips
• Use slip-resistant footwear.
• Clean up floors and working surfaces promptly when they become wet.
• Provide warning signs for wet floor areas.
• Practice safe housekeeping procedures, such as cleaning only one side of a passageway at a time.
• Where there are wet or oily processes, maintain drainage, platforms, nonslip mats or floor surfaces, or other dry standing areas. Use no-skid waxes and surfaces coated with grit to create nonslip surfaces in slippery areas such as toilet and shower areas.


5. Keep Work Areas and Emergency Exits Clear:

Make sure to remove any clutter blocking emergency exits, equipment shutoffs, and areas that you are working. A cluttered work area can lead to not having enough space to use tools and pick up heavy objects properly. Furthermore, if an exit is obstructed, you may not be able to quickly escape if an emergency occurs. Placing equipment in proper storage areas after use will help keep the work area and emergency exits clear.


6. Eliminate Fire Hazards:

If you are using combustible materials in the work environment, only keep the amount you need for the task at hand. When you are not using the flammable material, store the chemical in an assigned safe storage area away from sources of ignition. Also, store combustible waste in metal receptacles and dispose of it daily.
To prevent dust accumulation, use industrial vacuums to frequently clean areas where dust gathers.


7. Avoid Tracking Hazardous Materials:

To ensure that hazardous materials are not accidentally tracked into other areas, make sure that work area mats are maintained and kept clean. Prevent cross-contamination by using different cleaning materials—such as mops—for various spills, and change clothes if you spill toxic materials on them. Also, if you work with toxic materials, do not wear your work clothes home.


8. Prevent Objects from Falling:

To keep objects from falling, use protections such as nets, toe boards, and toe rails. In addition, stack boxes straight up and down, and place heavy objects on lower shelves. Furthermore, keep stacked objects out of the way of aisles and work areas.


9. Use Correct Posture when Lifting:

To avoid injuring your back when you are trying to pick up an item, keep your back straight, use your legs to lift, and pick up the item without stooping or twisting. Whenever possible, use mechanical aids such as a conveyor belt, wheelbarrow, or forklift.


10. Take Work Breaks From Time to Time:

Many work-related injuries occur when a worker is tired and cannot adequately observe dangers in their surroundings. By taking regular breaks, you are able to stay more alert when working.

What you need to know about Automatic Voltage Regulator,AVR

An automatic voltage regulator (AVR) is a electronic device for automatically maintaining generator output terminal voltage at a set value under varying load and operating temperature. It controls output by sensing the voltage output at a power-generating coil and comparing it to a stable reference. The error signal is then used to adjust an average value of the field current.

Most cheap portable generators have fixed excitation. In such machines, when an alternator is loaded, its terminal voltage drops due to its internal impedance. This impedance is formed of leakage reactance, armature reactance and armature resistance. The Vout also depends on the power factor of the load. That’s why to maintain Vout within tighter limits, more expensive models use an AVR.

N:B All AVRs help regulating the output in a steady state operation, but are generally slow to respond to fast transient loads.

Q: What will happen if we removed the AVR from the generator circuit?

A: If you remove an AVR from Generator it means that we removed the heart of generation of the alternator, It will not receive voltage to excite to generate voltage. Automatic Voltage Regulator, acts as a capacitor storing power, any spikes in power is held and stored by the AVR circuit capacitors thus delivering the set voltage range which should have been done with pre-delivery inspection. Removing the AVR in the total generator circuit will give you fluctuations in output power. It is very important to get your engine speed to correct RPM before adjustment of AVR is done. If engine RPM is out of range. You stand a huge chance of blowing your AVR.
Removing the AVR in the total generating set circuit will give fluctuations in the output power.

Remark: It is very important to get your engine speed to correct RPM before adjustment of AVR is done. If engine RPM is out of range. You stand a huge chance of blowing your AVR.

Facility Condition Assessment

Companies know how their productivity partly depends on their industrial maintenance processes. Each company has very precise needs and therefore has to implement a specific type of maintenance.


Importance of Maintenance in Business


Many industries can confirm how maintenance costs represent a high share of operating costs. Figures obviously vary from one company to another but they can still sometimes represent up to 50% of the global production costs, without even taking into account planned or unplanned downtime, stock and tools management, purchasing… There are as many unforeseen events which can lead to additional costs that a company often struggles to estimate but that are nonetheless closely linked to the maintenance teams’ activity. It goes without saying that an organization’s profitability and productivity partly depend on the maintenance processes that have been implemented.

In order to help you make the right decision and deploy the perfect strategy, we want to discuss the different types of industrial maintenance, its application, when such maintenance is required and one of the many maintenance priority differentiation methods.


Types of Maintenance


The various types of maintenance that follow, however, can be applied in any combination within an organization.


Preventive Maintenance, PM ( Planned Preventive, Planned, Scheduled)-


Preventive maintenance is maintenance performed with the intent of avoiding failures, safety violations, unnecessary production costs and losses, and to conserve original materials of fabrication. The effectiveness of a preventive maintenance schedule depends on the RCM analysis which it was based on, and the ground rules used for cost efficacy.




Can be time-based or condition-based. As the terms imply, these methods define schedules either based on a set period of time (e.g. every 30 days) or on a specified condition (e.g. every 500 hours ran). Most PM plans include both methods.


When to apply-


Most critical assets should have a PM plan, because assets that break down more often and more catastrophically will benefit the most from regular, inexpensive maintenance activities. Lower frequency of breakdowns means less downtime and overtime costs, extended equipment lifetime, increased production efficiency, and increased maintenance team productivity .


Predictive Maintenance (PdM)-


Predictive maintenance
More recently, advances in sensing and computing technology have given rise to predictive maintenance . This maintenance strategy uses sensors to monitor key parameters within a machine or system, and uses this data in conjunction with analysed historical trends to continuously evaluate the system health and predict a breakdown before it happens. This strategy allows maintenance to be performed more efficiently, since more up-to-date data is obtained about how close the product is to failure.




Predictive maintenance is really only condition-based, but with more precision. Instead of performing maintenance tasks after a certain number of hours ran, for example, thresholds can be vibration rates, temperature, or pressure. This often requires sophisticated sensors to monitor conditions, which can be continuous or periodic. Industrial Internet of Things (IIoT) plays a big role in PdM.


When to apply-


PdM can be a very effective maintenance method in the right situation. A predictive maintenance plan is usually more relevant with more precise data on causes of breakdowns and inefficiency. This strategy can require expensive monitoring equipment, but its implementation can save money in the long run.


Corrective Maintenance (RM, or Breakdown, Run-to-Failure, Reactive)-


Corrective maintenance is a type of maintenance used for equipment after equipment break down or malfunction is often most expensive – not only can worn equipment damage other parts and cause multiple damage, but consequential repair and replacement costs and loss of revenues due to down time during overhaul can be significant. Rebuilding and resurfacing of equipment and infrastructure damaged by erosion and corrosion as part of corrective or preventive maintenance programmes involves conventional processes such as welding and metal flame spraying, as well as engineered solutions with thermoset polymeric materials.




Reactive maintenance can be immediate or deferred. For assets that significantly hinder operations, immediate action should be taken. However, breakdowns on less-critical equipment may sometimes be deferred until resources are available.

When to apply-


RM is typically most effective on non-critical assets. This is because a low cost of replacement/repair on these assets, as well as a low probability of failure don’t merit the costs of more frequent PM or of monitoring equipment required for PdM. Reactive maintenance is free to set up, but the higher frequency of breakdowns becomes expensive to apply for critical asset

One way of differentiating maintenance priority between assets is as follows: Asset Criticality Value = (probability of failure) x (consequences of failure) .Assets with a higher criticality value should receive more maintenance resources. Since we can assume that all companies have the goal of operational reliability and are faced with limited resources, reliability-centered maintenance and risk-based maintenance should both be generally-accepted practices.

In conclusion, most organizations use some combination of preventive, predictive, and reactive maintenance as their maintenance strategy. A maintenance plan should carefully consider the needs of the company and the criticality of each asset.

The Challenges of Co-location Technology in Nigeria


The Challenges of Co-location Technology in  Nigeria

Spencer Itive | MCP, PMP, COREN |


The introduction of co-location technology as a way of mitigating at least the challenges of deploying telecoms services in Nigeria is yet to yield fully the expected desired results.

This is because Telecoms Operators instead of leveraging infrastructures sharing in its full potential, have continually undermined the benefits accrued from it.

This has left  deployment of GSM services huge challenges which this paper will  critically term  to examine.

 Nigerians embraced the Global System for mobile communications (GSM) when it was introduced far back 2001. This was because the citizens have been starved of mobile communication and often thought it was alien to them for years.

As they basked in this euphoria, the number of subscribers began to increase but without a commensurate significant increase in infrastructures rollout to withstand this growth level of subscribers.

Telecoms operators however, blamed the situation on government’s negligence in building infrastructures for network rollout. This, the operators complained has left them investing their hard earned profit in infrastructures rollout such as building and installing base stations and general operations of these sites.

However, the advent of colocation technology brought massive transformation in this sector as well as provided respite for telecoms operators. Here, telecoms services providers routinely enter into agreements with one another to share networks and other assets. These arrangements  facilitate interconnection between network; satisfy mandated asset sharing required by law or regulatory authority in order to promote competition; and help carriers maximize their use of assets, manage risk and build business cases with improved returns on investment.




Colocation technology is a system that allows telecoms operators to share some  type of physical space with other operator(s) , often competing operators. Colocation services provide significant technical and cost advantage in managing telecoms business. The bulk of colocation services entails collaborating to share either the active elements (the physical network) or the passive elements of their base station, which include the physical tower structure, security and diesel- powered generating sets, amongst others.

Colocation, which is a “cost reduction model”, is the provision of space for a customer’s telecommunications equipment on the service provider’s premises. Basically, there are two options of colocation technology for telecoms operators:

  • Third party service provider, provides a site and facilities, for instance, a tower for one or more operators to mount their equipment like radios and antennas.
  • Operator to operator agreements, where an operator offers one or more operators a space in his location / premises to share some infrastructure .

The cost of sharing facilities and colocating is reasonable compared to the cost of building one’s own infrastructure, hence a faster return on investment and an opportunity to focus more  on core business of the companies which is providing quality telecom services.



The following are the list of co-location independent service providers in Nigeria:

  • Helios Towers Nigeria limited, HTN
  • IHS Towers Plc – Tower of Strength
  • Basnik Telecoms
  • Swap Technologies Limited
  • Capcom
  • American Towers Company, ATC
  • Netcom African Ltd.



  • High operational costs in the Nigeria Environment due to poor availability of power. Poor grid availability makes investments in transformers and grid connection non-economical.
  • Lack of good quality diesel.
  • Lack of timely delivery of diesel to site due to activities of miscreants or Area Boys on sites.
  • Lack of proper operational template for sites.
  • Security.
  • Lack of adequate implementation  of the regulation and legislation by the governing body.
  • Lack of patronage by some operators.
  • Multiple taxation fees and levies, prohibitive charges to procure right of way.
  • Activities of Host communities.
  • High CAPEX.
  • Vandalization.
  • Fear of sabotage from  perceived competitors.



  • Generating sets.
  • Transformers (PHCN)
  • Shelter space
  • Security personnels
  • Security/guard hut
  • Air conditioners (in case of indoor)
  • Rectifiers
  • Towers /mast structures
  • Rack space
  • Shelter/equipment plinth
  • D.C source
  • Transmission link  – cables, fibres , etc
  • Earthing protection system
  • Access road
  • Site space
  • Gantries
  • Network operating centre, NOC
  • Maintenance personnels
  • Telemetry
  • Power Interface Unit, PIU
  • Uninterrupted Power Supply, UPS
  • Inverter
  • Hybrid



  • Telecoms operators can achieve up to 60 percent OPEX and CAPEX reduction as Co-location services are efficient.
  • Reduces proliferation of masts.
  • It enhances service quality.
  • Reduces noise and air pollution round sites/environment.
  • Reduces business risks.
  • It enhances healthy competition amongst telecoms operators leading to reduction in call tariffs.
  • Increased entry speed for new telecoms service providers.
  • It enhances customer satisfaction.
  • It improves the economy.



The opportunity has now come for telecoms service providers to stop the blame game and the unnecessary battle for superiority and supremacy , and embrace fully the co-location technology. These arrangements facilitate interconnection of networks, satisfy mandated asset sharing required by law or regulatory authority in order to promote healthy competition and improve service quality , and help them maximize their use of assets, manage risk and build business cases with improved returns on investment.
