WEC Energy Group depends on coal to produce a major portion of its electricity. No doubt the company is working to comply with stringent environment regulation. However, installation of low-emission infrastructure at its generation systems to meet regulatory compliance will increase its cost of operations. Further, the company is subject to operational risks associated with the breakdown or failure of equipment or processes due to fuel supply or transportation disruptions, accidents and labor disputes or work stoppages by employees. However, WEC Energy Group’s investments in infrastructure projects will help it to meet increasing customer demand and improve service reliability. WEC Energy Group’s decision to acquire Integrys has been fruitful, adding nearly $620 million to the company’s top line in the second quarter.
