Why Mines are Turning to Renewables?

This thought leadership piece provides insights from Rob Lydan and Michael Carreau of Hatch’s renewable energy team. The two offer perspectives for mining companies on the economics of wind and solar energy. They also present the challenges of integrating hybrid power solutions, and the 10-20% potential cost savings from moving towards alternative energy solutions.

If you asked miners to describe renewable power, you’d often hear words like ‘unreliable’, ‘expensive’, and ‘risky’, says Rob Lydan. That was up until quite recently. Lydan acknowledges that for many years, solar, wind, hydro, and other forms of renewable energy were intriguing. But, they seemed too expensive and too cutting-edge for the comfort of the mining industry. However, that’s all begun to change.

Over the past few months, the capital costs for renewables have continued to drop considerably. Consequently, many renewable solutions are now less expensive than diesel. “Wind power in a remote mining installation can reduce your cost of energy by 10-20%,” says Michael Carreau, Hatch’s Director of Renewable Power.

At the same time, the ability to engineer a hybrid renewable solution that is highly reliable has increased. With proper implementation and education, Carreau and Lydan are convinced that a hybrid renewable energy system can work just as reliably as running diesel generators on their own.

Utility-Scale Solar Ontario

Hazard Analysis

Phoventus was contracted to provide engineering support of Solar project ARC Flash Assessments for 3 Ontario Utility-Scale Solar Projects.

Between December 3ʳᵈ, 2018, and February 28ᵗʰ, 2019, Phoventus provided a full-wrap arc flash study, including prerequisite studies and data collection. A site inspection took place between January 3ʳᵈ, and January 6ᵗʰ, 2019. The study was completed using ETAP 18.1.1 and included both DC and AC studies.

This work conformed to the following standards: ANSI (1/2 Cycle), IEEE
946, IEEE 1584-2002, DC Arc Flash (Stokes & Oppenlander).

Onsite assessments / Solar project ARC Flash

Several regulations, codes, and standards define requirements for Arc Flash safety, including OSHA, NFPA 70E, CSA Z462, IEEE 1584-2018, and NESC. Article 130.5 of NFPA 70E requires employers to perform an Arc Flash risk assessment for electrical equipment and to update the study every five years.

Alberta Loadflow – Interconnection Engineering

Alberta Loadflow

Utility Scale Solar

 

Performed due diligence, review and capacity assessment

Performed due diligence, review and capacity assessment for interconnection of a 150MW solar facility to the transmission system in Southern Alberta Region. Recommended the most viable and cost-effective connection point to the transmission system following detailed calculation of stability limits, thermal ratings and load-generation capacities in the designated planning area. Alberta Loadflow and Capacity analysis was a success.

Utility Scale Energy Storage System

Energy Storage

Phoventus was contracted by Recurrent Energy in order to provide engineering support in assessing the Energy Storage System (ESS) Integrators’ bids for the 45MW/180MWh Slate Project in Kings County, California. The quality and quantity of documents submitted by the bidders differed significantly. In addition, the level of conformance to the RFP was varied, and the underlying assumptions in each bid diverged from each other.
