Bye-bye dirty diesel gensets for remote mines

THEnergy-Triogen report analyses how remote microgrids can be optimized by efficiency improvements of diesel gensets

The year 2019 was the turning point for renewable energy projects at remote mines. More than a dozen projects were commissioned or announced. Mining companies have adopted solar and wind power to reduce their energy cost and carbon footprint.

In the last years, successful flagship projects have removed concerns about production loss and independent power producers (IPPs) have started financing solar and wind plants at remote mining sites; IPPs sell electricity to miners on a power purchase agreement (PPA) basis. To mining companies, the PPA-cash flow is similar to what they are used to from diesel contracts – but it comes with cost reductions. IPPs are highly specialized in electricity generation, they are also looking at other solutions for cost reduction. It is no surprise that diesel genset efficiency optimization have also sparked interest. Diesel engines only convert 40% of the fuel energy into electricity, while the rest is not used. Waste heat recovery can reduce diesel consumption by approximately 7%. The approach is based on conventional steam turbine technology, but advances have allowed this to be deployed at a smaller scale. It is already proven in applications like biogas engine heat recovery, biomass combustion, industrial waste heat, and geothermal heat.

 

“Waste heat recovery is the low hanging fruit in the diesel reduction game,” points out Dr. Thomas Hillig, Managing Director of THEnergy, a Germany-based management consultancy specialized in cleantech innovations. “Renewables have recently opened the door for new approaches because they have increased the acceptance of more capital-intensive solutions in the mining industry.” The report “System optimization of renewable energy microgrids with heat-recovery in remote mining” shows that heat recovery can also go hand-in-hand with renewable energy approaches for diesel reduction. In a time when cost optimization and carbon mitigation are gaining importance, the question is not which of the two solutions to choose. The answer is to combine both solutions together.

The Dutch manufacturer Triogen has developed a containerized “e-box”, a solution that is tailor-made for remote mine sites. It has been designed for easily upgrading any diesel genset without changing its operations and thus without affecting maintenance or warranty requirements. The solution is based on the conventional steam turbine technology, yet is fully automated, compact and simple to install. Two standard 20-foot shipping containers are connected to the exhaust gas stack of diesel gensets and the e-box generates electricity from the waste heat. The electricity is fed into the local grid, so that diesel gensets do not need to produce this power and subsequently consume less fuel.

Triogen’s technology has accumulated over 1 million operating hours on 50 installations. The e-box solution has successfully been field-tested for mining applications and is now being deployed at the remote site of a blue-chip mining company. Henning von Barsewisch, CEO of Triogen adds: “Our containerized e-box has created sustained awareness from mining companies, IPPs, diesel genset OEMs and rental companies because of its short payback time of 2 years and its quick and easy deployability.” Since the Triogen e-box converts waste heat, it is a zero-carbon technology which addresses the drive for cleaner mining. A single e-box saves 300.000 liters of diesel per year. This is approximately the same as a 0.7 MW solar power plant in a rather sunny region. Annual CO2 reductions amount to 800 tons per e-box. In the quickly growing market of renewable energy solutions for remote mines, efficiency improvements of gensets can generate competitive advantages for mining companies and energy providers by pulling all the cost-efficient diesel reduction levers of onsite power plants.

Renewables to become the new normal at remote mines

The Energy and Mines World Congress shows that 2019 will be considered the tipping point for solar and wind projects in the mining sector 

The Energy and Mines World Congress that took place in Toronto provided great insights into the recent developments of onsite renewable energy applications at remote mines. Generally, the year 2019 has been identified as the tipping point. The business case for partly substituting expensive fuel like diesel, heavy fuel oil (HFO) or gas by solar and wind had been positive on paper for years. However, actual projects have evolved slowly. In 2019, almost a dozen new projects have been officially announced and at the same time many more projects are under development and on the verge of being announced.

Major on-site solar and wind power projects in mining

Nick Holland, CEO of Gold Fields, a mining company that is a pioneer in integrating renewables, pointed out in his keynote that costs savings are possible, and a cost-efficient decentralization of power generation enabled by renewables comes with further advantages: “Renewables make for great business – lower cost and supply security. Independence from the grid is critical – microgrids are the future!”

 

Sustainability goes well beyond renewables

Mining companies see the need to decarbonize and pursue initiatives that go well beyond renewables, such as electrification of mining vehicles. These initiatives will further increase the electricity demand in mining and in the long run the need for locally generated renewable energy.

 

Trust in renewables has been building up over the years

Miners are gaining trust in renewable energy solutions. The fear of production losses has been decreasing over the past years with every new renewable energy system that has been added to a mine globally. Before, the general attitude was characterized by “wait and see”, but the mode has been changing in 2019 to “let’s act now”. The individual decision makers today run a relatively low perceived risk by driving forward renewable energy projects. The solutions that are being built now are often more sophisticated than they were before, and they incorporate a higher share of renewables that is also enabled by storage solutions.

 

Australia and Africa are leading the way

The epicenters of these developments are Australia and Sub-Saharan Africa, two regions having substantial areas with insufficient public grids and typically excellent solar resources. At the same time, renewable energy development also has a local driver. Though the mining sector is rather global, the word-of-mouth and political pressure on mining players to add renewables unleashes additional speed on a local level.

 

Shorter power purchase agreements (PPAs)

In comparison to the physical lifetime of solar and wind assets, the lifetime of mines or the mining licenses are often rather short. In addition, miners are used to relatively short-term energy supply for diesel, HFO and gas. Long-term purchase agreements for renewable energy often require a change of thinking and have slowed down the development of many projects in the past. More and more companies have come up with redeployable solar solutions that allow for offering short-term PPAs. On the hardware-side, the costs of redeployable solar solutions have come down significantly, but at the same time this approach is a bet on future growth of this segment. Redeployability also means that new target projects need to be available within a reasonable time period in the future. If not, the solar assets would have to be stored in warehouses until new deployment, which can prove to be costly.

 

Combining different renewable energy sources and energy storage

Several newly announced projects combine solar and wind power. One of the biggest disadvantages of solar and wind solutions is that they generate unsteady energy. Solar and wind output are often negatively correlated, which means that when solar irradiation is high wind speeds are typically low, and vice versa. This phenomenon allows for increasing the renewable energy share in the system while minimizing the need for storage.

In his presentation at the Energy and Mines World Congress, Thomas Hillig, Managing Director of the consulting firm THEnergy, said that for mining companies it makes sense to consider all sustainability levers and that also hydro could experience a real renaissance: “In a research project that is supported by the German government with approximately USD 1 million, THEnergy is analyzing in collaboration with two universities, RWTH Aachen and TU München, the potential of hydro-electric solutions in the mining sector. We are still looking for mines in Peru to participate - free of any charge.”

Renewables require real marketing and branding – like other sectors

Renewables require real marketing and branding – like other sectors

Electricity is extremely abstract, which makes it nearly impossible to differentiate at the product marketing level. For the first hundred and fifty years of the category, especially in regulated or nationalized markets, differentiation was not even required. Liberalization and deregulation of the energy markets has produced new and unstable playing fields for energy providers. The pace of accelerating liberalization across global markets has created extraordinary challenges for energy companies as they struggle in their nascent efforts at brand building and product marketing.

For energy companies, differentiation, is mainly done based on product-support services and the origin of the electricity. The origin, or source of their power, is one of the most top-of-mind topics in the global consciousness, especially for the millions of young people demonstrating each week in the streets against the ticking clock of climate-death countdown

The energy industry is acutely aware that electricity and heat generation accounted for more than 40% of the world’s total greenhouse gas emissions. To achieve the 1.5-degree objectives from the Paris Agreement, it will be mandatory to decarbonize these two sectors almost fully. Although clean or renewable energy generation costs have come down significantly during the last several years, this trend hardly reaches the end-customers – neither private households nor corporations.

 “To some extent, this is due to a lack of marketing and branding”, points out Dr Thomas Hillig, Managing Director of the Germany based energy consultancy THEnergy. And this is why THEnergy and New York based Free Radicals have set up a new partnership. Hillig continues: “We help our client partners to pull the available and appropriate marketing and branding levers. In the end, this will also contribute to accelerate the energy transition.”

Free Radicals and THEnergy combine two approaches that will give customers radical insights – also quantitative. Research is generative, focused on value outcomes for the business. The partnership leverages the complementary tensions between the unique disciplines of the two consultancies.

Both partners highlight the importance of “unMcKinsey-thinking”. “You have to make some trouble to get attention for your brand”, emphasizes Thom Kennon, Managing Director of Free Radicals. “Happy talk about innovation and disruption will not solve the business, brand and marketing problems these energy companies face. In our unorthodox workshops we develop street-ready strategies that can start paying bottom-line dividends within weeks and months not quarters or years.”

The brand-building and marketing functions within energy companies do not historically enjoy a central seat at the business planning table.  The new approach tackles this problem in two ways. First, Marketing insights around the customer can and should inform all strategic planning. Second, leveraging the marketing function as the essential connection point with the customer and the market to deploy, test and optimize rapid and cost-effective initiatives for business-building.

 

”Making some trouble means  designing initiatives where the brand shows up in the customers life with surprising saliency. It’s about a new kind of value marketing, suited to the needs, lives and consciousnesses of the emerging generation of energy consumers.   

 

The target clients for the new approach include both large  utilities who have read the signs of the times and are prepared to join the honest fight for new customers, as well as emerging energy providers  who are poised opportunistically to make some trouble for the incumbents – both in B2C and B2B electricity markets.

Huge potential for renewables in the telecom sector

Substantial cost savings achievable and a USD 100 billion+ investment opportunity for onsite renewables

Telecom companies like AT&T, T-Mobile, BT, Euskaltel, and Telstra have signed some of the biggest corporate power purchase agreements (PPAs) to date. Telecommunications giant AT&T is ranked second in corporate PPAs and BT is only one step short of being 100% renewable on paper.

A recent IRENA report reveals, however, that globally, telecommunications companies only cover around 7% of their electricity needs with renewable energy resources and only 19% of the analyzed telecom companies had renewable energy targets.

Powering telecom towers with renewables is a great opportunity – especially for towers in remote locations. Typically, these towers run on diesel gensets that require significant costs for operation and maintenance. The recent price decrease of solar and batteries allows at least for partially replacing diesel by renewable energy sources.

One industry trend is the outsourcing of telecom towers. Tower companies build, operate, and maintain these assets – often on behalf of several telecom operators. This means at the same time that the corresponding emissions are normally not attributed to the telecom companies themselves. Public pressure is considerably lower for outsourced C02 emission.

Experts estimate that globally there are more than 3 million telecom towers. It has become obvious that the potential for renewable energy solutions is therefore huge. This also applies for energy storage as telecommunication applications require extremely high availabilities. The total market is estimated at far beyond USD100 billion.

The extreme price decrease of renewables makes onsite solar and wind energy often less expensive than electricity from the grid. The approach is straightforward: when onsite power is available, it will be used for the tower, if not, electricity will be used. If there is an outage, the back-up gensets provide an emergency supply.

The business case is even more favorable for off-grid towers. In a first step, diesel gensets still run 24 hours to generate a spinning reserve in case a solar array is shaded, or the wind stops. In a second step, renewables can be integrated in a way that diesel gensets are switched off during sunny or windy periods so that the tower fully relies on solar or wind energy. When solar or wind outputs do not meet the power requirements of the tower, energy storage acts as a bridge to start the back-up diesel gensets. Finally, adding even more solar or wind power would mean that the towers are powered also during night-time or during less windy periods by renewable energy that is stored in large amounts. Back-up diesel gensets would only be required in case of very unfavorable seasonality. Innovative companies also have developed concepts of combining the renewable energy-based power generation for telecom towers and neighboring villages.

The biggest hurdle is the high investment requirements for renewables. However, more and more independent power producers (IPPs) are entering the market and are willing to invest in renewable energy and storage assets. They would then sell back the electricity to the tower operators – i.e., either the tower company or the telecom operator.

Resolute Mining procures 40 MW solar hybrid power plant for its Syama mine in Mali

The Australian mining company Resolute has signed a joint development agreement with Ignite Energy for the development of a 40 MW independent solar hybrid power plant at its Syama gold mine in Mali. The microgrid will combine solar, battery and heavy fuel oil technologies and will replace the existing 28 MW diesel-fired power station at the mine. It is expected to be operational by the end of 2020.

John Welborn, CEO of Resolute Mining Limited explains: “The Syama Gold Mine in the South of Mali is one of the most advanced underground mines in the world. Resolute is building the world’s first fully automated underground mine and we will power this mine with the largest off-grid hybrid power plant ever implemented for operating a mine.  The combination of leading solar, HFO, and battery technology will provide Syama with sustainable low-cost power for future expansion, and the potential to provide electricity to the local community.” “The potential of hybrid projects to remote mines in Africa is significant and is expected to grow through a combination of cost reductions and increased efficiencies of renewable technologies, creative financing solutions, and forward-thinking and open-minded mine owners”, adds Grant Berndsen, Managing Director of Ignite Energy Projects.

Caribbean island Bonaire combines solar, wind, diesel, and storage

Bonaire is part of the Netherlands Antilles. The Caribbean island will soon have a state-of-the-art microgrid that combines 11 MW wind, 6 MW new energy storage, a pre-existing 3 MW battery bank, and a small solar array. ContourGlobal has awarded Wärtsilä with the integrated 6 MW energy storage project contract for Bonaire. The renewable energy and storage assets will be used to limit the use of the 17 MW of diesel generators.

“The Caribbean will benefit greatly from hybrid projects. Primarily batteries will allow higher utilization rates for intermittent renewable energy. As an additional benefit, batteries can provide vital frequency support during any disturbances in a small grid keeping the lights on everywhere”, adds Sampo Suvisaari, Regional Director, Latin America North and Caribbean, Wärtsilä Energy Business.

Oman to install solar-diesel hybrid plants totaling 160 MW across 11 sites

State-owned Nama Holding’s subsidiary Tanweer – Oman’s Rural Areas Electricity Company – has launched the plan to build 160MW of hybrid solar-diesel power generation capacity in non-interconnected areas. The hybrid plants will be developed as independent power producer (IPP) projects at 11 off-grid sites. The final bid evaluation is planned for June, while contracts for the projects’ realization should be awarded in August.

GoviEx and Windiga working on hybrid solar power solution for Madaouela in Niger

GoviEx has requested that Windiga develops a concept to power the Madaouela project and the surrounding local community through a hybrid power plant combining solar panels and diesel generators, with a total installed capacity of at least 20 MW.  GoviEx targets a power purchase agreement for the priority supply of electricity for an initial term of 21 years, extendable at the request of GoviEx.

“It’s a tremendous time for the integration of renewables in the mining sector. The cost of energy using pure thermal solutions is becoming an issue for many operational mines and projects at the feasibility stage looking for financing. Contracted hybrid energy systems to an independent power producer can remove a significant part of the CAPEX while still offering great savings and predictability for the OPEX. Solar-diesel power plants are now unavoidable for this industry”, comments Benoit La Salle, CEO of Windiga.
