​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.

While a Duke Energy plan to build a combined heat-and-power project at Duke University remains on hold, the company is quietly moving ahead with a $50.8 million CHP project at Clemson University.
Duke Energy Carolinas proposes to build a 16-megawatt, gas-fired power plant on the campus. The plant will produce electricity for the grid. Duke will use the excess heat from the natural gas turbine to produce steam, which it will sell to Clemson for university heating.

The National Association of Clean Air Agencies (“NACAA”) has issued a report titled:
Improving Our Nation’s Clean Air Program: Recommendations from the National Association of Clean Air Agencies to President Trump’s Administration (“Report”)
The NACAA describes itself as a national, non-partisan, non-profit association of air pollution control agencies in 40 states, the District of Columbia, four territories and 116 metropolitan areas.
The Report is offered for consideration by United States Environmental Protection Agency Administrator Scott Pruitt and other members of the Trump Administration.
The Report focuses on what it characterizes as “key issues associated with our nation’s clean air program.”
The recommendations include:

• Improve technical assistance to state and local agencies
  
• Ensure state and local agencies have resources they need to implement federal requirements
  
• Improve regulatory assistance to state and local air agencies through effective federal measures for mobile and stationary sources
  
• Continue and expand efforts to address the transport of air pollution
  
• Ensure effective establishment and implementation of the National Ambient Air Quality Standards
  
• Address critical air monitoring challenges
  
• Identify and address toxic air pollution challenges
  
• Support state and local efforts to address climate change
  
• Improve the integration of federal, state and local data programs and requirements

Proposed changes to N.J.A.C. 7:27-16 and 19: VOC and NOx RACT...The new rules will affect major sources of VOC and NOx emissions, and include various emission limits and parametric guidelines. Some of the industries affected would be: surface coating operations, shipbuilding, screen printing, and major sources who operate simple cycle combustion turbines, compressor turbines, or compressor engines rated between 200 and 500 hp on natural gas. Compliance with the new limits may require applicable facilities to install emission controls. Permit modifications will be required.
