WRAL.com reports the North Carolina Sustainable Energy Association believes the renewables standard has saved customers $162 million since it was approved in 2010. Strata Policy has estimated the mandates is costing about $3,500 per family.
The proposed bill strikes language directing a renewables standard and instead says energy will be procured "in a manner that is consistent with the development of the least cost mix of generation."
What is clear, however, is that renewable energy mandates and a decline in natural gas prices played a role in pushing out coal-fired generation.
Coal-fired power plants provided more than half of the electricity generated in the state before 2012, but now that is less than a third according to the U.S. Energy Information Administration. On the other hand, renewable energy and natural gas generation increased rapidly.
"The amount of electricity generated from solar energy in North Carolina has increased rapidly," EIA said. "With 2,294 megawatts, the state has the third-largest installed solar capacity in the nation."
Wind energy is also growing in the state as federal agencies seek to open up offshore tracts to bidders. Last month, the Bureau of Ocean Energy Management announced it would lease 122,405 acres offshore North Carolina to Avangrid Renewables, for development of a wind energy facility off Kitty Hawk. It would be the company's second wind facility in the state; Avangrid previously developed the 208 MW Amazon Wind Farm.

Combined Heat & Power (CHP) refers to a suite of technologies to simultaneously generate power and thermal energy from primary energy sources like natural gas. Most CHP systems are “topping cycle” since electricity is the primary product and waste heat is recaptured and reused. The core components of a CHP system include a “prime mover” such as a Gas Turbine (GT) or Reciprocating Engine (RE) tied to a Waste Heat Recovery (WHR) unit. The WHR unit can be a steam or hot water boiler or counter-intuitively a Vapor Absorption Chiller (VAC); basically a heat exchanger that uses otherwise wasted heat to make chilled water.
Data Centers are a densely packed cluster of computers and are critical nodes of today’s internet. Unless you are an “off-grid” ascetic, in which case you would not be reading this story -- you depend on a DC each time you access the internet through your computer or your smartphone for trivial (facebook photos) or important (reading this article!) tasks.
So what’s the link between CHP and data centers? Technically speaking, well-designed CHP is a foundational element of data center system design and deployment. In economic terms, a CHP system must improve the economics of a DC. What does this assertion mean? Let’s start by listing data center “wants and needs”, then map to the features and benefits of CHP.
