Why the Change to DC?

Solid state electronics need DC power, not AC power

AC was popular at cell sites because air conditioning units needed large amounts of AC power. Over years, the electronics became more immune to temperature extremes and no longer require air conditioning

This advance in electronics broadened the market for DC generators and power systems

Polar has successfully overcome 100 years of AC power legacy. Our sales are growing rapidly as engineers and managers experience the advantages of our DC power technologies

Why Choose Polar Power?

• Optimized core product technology over 20 years from both a cost and performance perspective and now deliver a turnkey system

• Provide technical support for our customers including their: architecture and engineering (A&E), installers, commissioning, maintenance, local, regional, and national project managers. Support goes beyond just that of the DC power system

• Rapidly change the product to keep up with the constantly evolving telecommunications infrastructure and power requirements

• Manufacturing the product in volume with 8-week delivery schedules

31Polar Power Engineered Backup & Prime Power Solutions Specifically for Telecommunications Applications

History shows that reliability, low maintenance, and fuel efficiency are necessary when it comes to an

actual emergency. To help solve for these issues, Polar engineered a fuel efficient generator with the

following features:

1. Eliminated the Starting Battery. This is the number 1 reason why generators fail to start. Polar uses a

Supercapacitor to start its telecom generators. Providing the highest amount of cranking amps during

the coldest weather. Providing 15 to 20 years of reliable service in the hottest and coldest weather

extremes.

2. IP65 Sealed and Electronics. To ensure reliability during storms or flooding, all electrical connections

and components are sealed and water tight.

3. No Transfer Switches. Polar’s DC generators connect directly to the battery (through fuses or circuit

breakers).

4. NEMA 4 Storm Resistant Enclosures. Designed to minimize the intrusion of rain and snow.

5. Corrosion Resistant. The all aluminum frame is a unitized, welded and powder coated enclosure with

stainless hardware for corrosion resistance and durability.

6. Remote Monitoring and Control. Real time access to operational status, fuel level, fault diagnosis

and maintenance schedule of our products is critical to reliability and makes more efficient use of

assets and vital human resources. Offers the capability of off loading management of power

producing assets to out of state personnel or Polar Power.

During an extended storm or disaster the mission of a backup generator changes to prime power

32Polar Power Engineered Backup & Prime Power Solutions Specifically for Telecommunications Applications

“All fixed and portable gensets require constant refueling, usually once a

day, which presents important logistics issues.”

“Taking the genset to a site is usually complicated, because roads may be

damaged or filled with debris and bridges may have been washed away.”

-Katrina NSF report UILU-ENG-2006-2511

Detailed reports on the problems with AC Generators during the Katrina hurricane are available on the internet and include: CEME-TR-06-05 and CRPT-109srpt322

Think of the disruption of communication as one AC generator goes down and the time it takes to get another one to site along with the logistics to make it happen. And where do all these additional generators come from during the disaster? What is the cost to maintain a larger reserve of portable generators or the cost to get on the spot market during a disaster?

34Why Telecoms & Commercial Companies Need Backup Power or Uninterruptible Power Supply (UPS)

• Mission-critical businesses can’t afford to be without power, even for less than a second

‒ Data centers‒ Financial institutions‒ Hospitals

• Results are lost revenue, customers and human safety

• Telecoms – FCC requirement for all cell towers to have some form of backup power following Hurricane Sandy

• More businesses are questioning the reliability of today’s public power grid

• Natural disasters – earthquakes, floods & tornados

• Blackouts and rolling brownouts due strain on public grid during peak demand

• Onsite power generation and storage provides backup power to enable telecoms/businesses to function without interruption

MOVING AWAY FROM AIR CONDITIONING

Radios’ ability to operate at higher temperatures eliminates the air conditioning at site, creating significant energy savings and opening the market for DC generators

36

Why a Telecommunications Focus?

Presently 4.7 billion unique mobile subscribers and 5.7 billion projected by 2020 (1)

Telecommunications companies worldwide will invest over $1.4 trillion in the construction of new cell towers and equipment upgrades by 2020 (2)

Reducing energy cost presents a major opportunity to increase profit or lower subscriber fees

It is estimated there are more than 1,000 small and medium telecom companies in the U.S. alone

Currently, it is estimated that there are more than 300,000 cell sites in the U.S. (3)

New 5G rollout requires large tower and power expansion

37

Trends

FCC regulatory change and wireless carriers revenue goals demand longer backup capacity at all cell sites triggered by Hurricane Katrina & Sandy

Cell phones are displacing land lines as primary means of communications. Now the same level of reliability is being demanded of cell phones

Enhanced pressure from the EPA to reduce greenhouse gases

Necessity of independent towers and cell sites for first responders

Strict mandates to provide rural connectivity to broadband service in the U.S. and developing nations

Many wireless carriers are divesting their tower assets and in turn renting the space from the “new” owners; now referred to as Tower Operators.

Tower Operators have a narrow business interest of providing space and electrical energy; with new owners cell sites are now focused on reducing energy costs to increase their profits.

Advantages of DC Power Systems

• With air conditioning no longer required, during a power outage there is now the opportunity for smaller and more efficient DC power systems to provide backup power.

• Space is at a very high premium on the cell site. Polar’s DC power systems are smaller than many AC power systems.

• Polar’s DC power systems are lighter than many AC power systems, reducing roof reinforcing requirements.

• Polar’s unique fuel carburation system allows our power systems to function off line pressure without expensive booster pumps, typical of AC power systems.

• Isolation from the grid, no problems with the power system accidentally connecting to the grid• Quiet operation• Small amounts of fuel on site

40

Prime Power

Systems

Off-Grid Sites

• Fuel saving has been the most important reason for choosing Polar DC power systems. We can reduce fuel savings significantly over typical AC installations.

• Our DC hybrid systems reduce field maintenance and refueling from 1 to 4 times a month for traditional technologies to as long as 12 months.

• The CAPEX for an installed Polar DC hybrid system is typically lower than AC based systems.

• Our products are specifically engineered for low maintenance and long life in prime power applications; thereby reducing OPEX costs. Typically 20 kW AC power systems and smaller are engineered for a low cost applications, and not prime power; increasing the OPEX cost.

• Ease of transportation to remote sites.

• Remote monitoring and control.

• Built in battery charging algorithms.
