When mining companies are looking to purchase energy efficient and cost-effective onsite power generator, before they can receive an accurate a price estimate, they first have to know what power range they need and what traditional fuels, such as heavy fuel oil, diesel and natural gas, or sustainable fuels such as coal seam gas and biogas, they plan to use.

In addition, they have to consider the application, power need, fuel costs, infrastructure, service requirements, scope of equipment supply, transportation, logistics, and so on, according to Nick Kelsch, gas application consultant, Caterpillar.

All of these factors impact the power solution, and they also affect the cost. Every installation is unique in some respect, and it’s impossible to provide an accurate price without working through the details, Kelsch says.

Since the project scope and costs can still vary dramatically from site to site and country to country, installed costs can be significantly lower in lesser regulated countries due to differences in standards, emission requirements and labor costs, he adds.

The generator prices listed are for the usual onsite systems and are based on these four factors: 1.) Mechanical costs – engine generator, outdoor enclosure, fuel tanks or gas train, exhaust/silencer, radiator, air filters and mechanical contractor installation; 2.) Electrical costs  ̶ switchgear or transfer switch, communications, cable and conduit, batteries, breakers and electrical contractor installation; 3.) Commissioning  ̶  onsite liquid fuel fills, coolant, oil, technician service, project management and basic operator training; and 4.) Freight shipment of everything to a U.S. location.

  • Diesel Emergency Power System = $590 per ekW;
  • Natural Gas Emergency Power System = $720 per kW.

A 1,000 kW combined heat and power (CHP) system with the same assumptions as above plus heat recovery for hot water production can be estimated:

  • Natural Gas CHP System = $852 per ekW.

An installed and commissioned 1,000 kW, industrial-grade uninterruptible power supply (UPS) system can be estimated:

  • Battery UPS System = $470 per ekW.
  • Flywheel UPS System = $540 per ekW;

Operating costs for a 1,000 kW rental power system are as follows:

  • Diesel Rental Power Cost (100h with fuel at $4/gallon) = $0.52 per kWh;
  • Natural Gas Rental Power Monthly Rate (100h with fuel at $5/MMBtu) = $0.67 per kWh;
  • Diesel Rental Power Cost (600h with fuel at $4/gallon) = $0.36 per kWh;
  • Natural Gas Rental Power Monthly Rate (600h with fuel $5/MMBtu) = $0.23 per kWh.

Sometimes government regulation dictates priorities for power systems. Other times the cost of a potential power outage far outweighs the capital and maintenance costs, according to Kelsch. For a renewable biogas energy project, benefits are defined in terms of profit and reduced social costs such as reduced carbon and odor emissions.

Learn how to future proof your business for a zero-carbon world with help from Emitwise and the Oren Marketplace...

How do we get the world to net-zero faster?

Emitwise’s founders, Mauro Cozzi, Eduardo Gómez and Ben Peddie, approached a network of more than 100 of the world's largest enterprises and asked their CEOs, CFOs, and sustainability managers the big question: How do we get the world to net-zero faster? The challenge many shared was the lack of timely and accurate emissions data to enable strategic decisions. Companies often relied on annual audits of their carbon footprint for carbon accounting purposes. However, static yearly results were outdated upon publishing.

Emitwise saves companies an average of 260 working days a year by automating their scope 1, 2 and 3 emissions data. With the added benefits of clean audit trails and auto-populated accounting reports in line with GHG Protocol, all at the click of a button. Their easy to use solution enables businesses to quickly identify the carbon hotspots to target, and the precise real-time data empowers teams to remain agile and respond effectively, making achieving those goals possible.

Unique AI Technology

Emitwise’s unique AI technology empowers businesses to automatically measure, report and reduce their carbon footprint across their operations and supply chain, future-proofing companies for a zero-carbon world. It is the only solution that enables companies to fully automate their carbon accounting across all business units and suppliers, therefore liberating them from the drudgery of collecting and processing emissions data.

By using artificial intelligence to precisely measure emissions in real-time, businesses can identify and tackle carbon hotspots swiftly, enabling them to devise a trackable roadmap to net-zero carbon. At the same time, accurate audit trails and auto-populated annual reports ensure that companies comply with international reporting requirements, and align businesses with global climate targets to mitigate risk across their operations and supply chain. 

The Oren Marketplace

Environmental management, social license to operate, safety, renewable energy to lower emissions and operational efficiency for mining can be supported by a range of digital solutions enabling dynamic operations. To address these issues, Shell and IBM joined forces to create the Oren Marketplace – the first B2B solutions platform for the mining sector. 

With the adoption of many of the digital solutions offered through Oren, mining companies can adapt in real-time to risks or adjust plans ahead of a problem occurring. The goal is a shift towards proactive management as the optimal outcome for all stakeholders – community, shareholders, and employees.

Emitwise was founded with the goal of helping industries across all sectors reduce their carbon footprint. Similarly, Shell aims to become a net-zero emissions energy business by 2050, or sooner, in step with society and its customers. And Oren is focused on offering innovative products and services that can help mining companies track and reduce their emissions. 

“Oren is the starting point for how we help our mining customers to de-carbonise,” explains Carol Chen, Global Lubricants Marketing, Vice President, Shell. “It’s our ambition to work with sectors like mining to help them find their own pathway to net-zero emissions through collaboration. The Oren marketplace offers a great opportunity for collaboration between the miners and technology companies that are joining this digital marketplace.” 

Web Summit

Emitwise will be showcasing its vision for a net-zero future live from Lisbon at this year’s Web Summit. Bringing together the people and companies redefining the global tech industry, the online event welcomes 100,000+ attendees from around the world to hear from more than 800 speakers and view offerings from 2,500 startups covering a vast range of topics from Data Science and Climate Change to AI and Machine Learning. To find out more and book your ticket visit Web Summit. 

Emitwise is one of many solutions providers on the Oren platform seeking to address the pain points and environmental concerns of heavy industries like mining. To discover a range of solutions that can further support your operation’s digital transformation and commitment to sustainability, visit the Oren Marketplace.
