Power and Industrial Projects is comprised primarily of projects that deliver energy and utility-type products and services to industrial, commercial and
institutional customers, produce reduced emissions fuel and sell electricity from renewable energy projects. This business segment provides services using
project assets usually located on or near the customers' premises in the steel, automotive, pulp and paper, airport, and other industries as follows:
Steel and Petroleum Coke: We produce metallurgical coke from two coke batteries with a capacity of 1.4 million tons per year. We have an investment
in a third coke battery with a capacity of 1.2 million tons per year. We also provide pulverized coal and petroleum coke to the steel, pulp and paper and other
industries.
On-Site Energy: We provide power generation, steam production, chilled water production, wastewater treatment and compressed air supply to
industrial customers. We provide utility-type services using project assets usually located on or near the customers' premises in the automotive, airport,
chemical and other industries.
Wholesale Power and Renewables: We hold ownership interests in and operate five renewable generating plants with a capacity of 228 MWs. The
electric output is sold under long term power purchase agreements. We also develop landfill gas recovery systems that capture the gas and provide local
utilities, industry and consumers with an opportunity to use a competitive, renewable source of energy, in addition to providing environmental benefits by
reducing greenhouse gas emissions.
Reduced Emissions Fuel: We own and operate nine REF facilities. Our facilities blend a proprietary additive with coal used in coal-fired power plants
resulting in reduced emissions of nitrogen oxide and mercury. Qualifying facilities are eligible to generate tax credits for ten years upon achieving certain
criteria. The value of a tax credit is adjusted annually by an inflation factor published by the IRS. The value of the tax credit is reduced if the reference price
of coal exceeds certain thresholds. The economic benefit of the REF facilities is dependent upon the generation of production tax credits. We placed in
service five REF facilities in 2009 and an additional four REF facilities in 2011. To optimize income and cash flow from the REF operations, we sold
membership interests at two of the facilities in 2011 and at two additional facilities in 2013. We continue to optimize these facilities by seeking investors for
facilities operating at DTE Electric and other utility sites. Additionally, we intend to relocate certain underutilized facilities to alternative coal-fired power
plants which may provide increased production and emission reduction opportunities in 2015 and future years.
