Proven Energy is able to offer a unique global proposition to the dynamic telecoms industry, bringing power to remote telecom base stations and generating revenue from decommissioned base stations.

Off-grid telecoms base stations require a reliable solution. Diesel generations need regular visits for maintenance and refueling but a Proven Energy small wind turbine is able to generate energy independently. For on-grid telecom base stations, a wind turbine can supply power as well as generate energy from excess electricity produced.

Saudi Aramco Telecoms

Saudi Aramco, in Saudi Arabia, required an additional energy source to power its RS10 telecom base station.  Previously powered by solar photovoltaic (PV) panels only, increasing loads dictated that an additional generation device would be required. The base station is remote and many miles from a grid connection.

As a supplier of robust products, Proven Energy was selected to install a Proven 6 battery storage wind turbine to power the site. The Proven 6 generates up to 12,000 kWh per annum, exceeding the requirements of the base station. The turbine works at maximum efficiency, despite the harsh climate, and provides a cost-effective solution, requiring only annual maintenance. The solar panels have been removed and the site now relies solely on the wind turbine.

Motorola - Namibia

Motorola required a solution for powering a base station in Namibia that did not involve costly diesel generators. The base station provides phone power to Dordabis Village, with a population of approximately 1,500 people, and farming communities situated about 30km away.

The location of the base station was remote and there was no grid connection. Motorola required a reliable, cost-effective power source that could provide between 1,200W and 1,500W of continuous power. After a successful pilot project carried out by Motorola UK, a Proven 6 battery charging wind turbine system was installed. The Proven 6 generates up to 12,000 kWh per annum in high temperatures and requires only annual maintenance.

Soay Telecoms

BT has installed a Proven 2.5 battery charging system to power its base station on the Isle of Soay (off the west coast of Scotland).  BT required a reliable power supply that would operate with minimal maintenance. The base station was previously powered by a diesel generator which incurred high fuel and maintenance costs. The Isle of Soay has no mains power so BT relies on the turbine to provide a continuous supply of electricity. The turbine also powers BT's microwave link.  Conditions on this exposed island enable maximum electricity production.  The Proven turbine produces up to 5,000 kWh of electricity annually with continuous power supply supported from the battery pack.

Blesberg Telecoms

Vodacom South Africa uses a Proven 2.5 battery storage system to power a remote base station on Blesberg Mountain. The Blesberg telecom site has no access to on-grid electricity and requires a constant load of 1178W to power phone lines. The battery storage system ensures a continuous energy supply for the base station. Previously powered by a diesel generator, the base station had been expensive to run. The Proven 2.5 requires only annual maintenance, eliminating the need for costly refueling and regular servicing which had proved difficult due to the remote location of the base station. The Proven turbine produces up to 5,000 kWh of electricity annually and has been running at optimum levels since its installation in 2000.

Ideally suited to telecoms applications, the Proven 2.5 or Proven 6 offer a reliable solution to powering base stations. Proven Energy has worked collaboratively with BT for thirteen years as well as with a number of leading telecom providers. A Proven Energy turbine can be grid or battery connected, with each offering a continuous energy supply. Designed to IEC61400-2 standard, all internal components are suitable for low and high temperature climates.

Providing independent power reduces diesel run times and other associated costs of extending grid power to remote sites. A Proven Energy turbine can be used to complement other renewable energy technology. It is often used in conjunction with solar panels, providing an effective hybrid solution. Payback for a wind-powered base station is between two and five years, depending on wind speed and location.

"The collaboration with Motorola was a world first for us, resulting in an innovation we are all proud of.  We are enjoying the benefits of this solution and will be deploying more solar-wind powered base stations to many a rural setting to provide cost-effective solutions to our rural areas."
