programme of CHP/District Heating Conferences & Networking events held by GMP Publications Ltd have been crucial in promoting the latest ideas and technology. This year, in particular, we are offering a high-end conference with inside information suitable for elite bankers, developers, consultants, energy professionals, politicians & civil servants. “I’m pleased to say this Conference series has certainly fostered a reputation for providing both cutting-edge financial and technical information essential to project developers, engineers, architects and to suppliers of specialist equipment. How important is it to stay non-commercial? Is this at the core of the lectures? “Our Conferences papers are certainly not sales pitches for commercial operators. While it’s true we have to find companies to provide interesting presentations - these invariably feature unusual case studies, challenging situations and pitfalls to be avoided.” Why do you feel CHP & District Heating should be a cornerstone of this 4-part event? “In 2018 this is a topic of critical importance to everyone. It is gradually dawning on experts that the key issue in the UK today is how to heat buildings economically & efficiently. In fact, this can only be done realistically with the latest CHP and District Heating technology. This key realisation has opened up a huge market for independent power generation focused on at least 20 million homes. In total, this involves a capital investment reliably estimated to be in the region of £12 billion+ from 2018 onwards.” Do you think everyone gets the message that energy reuse is the way forward
in the 21st Century? “By no means. On average, the UK’s large, centralised power stations still throw away two-thirds of the energy they generate. If power stations - or factories - are sited close to where heat is needed - say, near towns and villages or industrial sites - then this heat can be captured and supplied to homes and businesses or used in other industrial processes.”
Typical
cogeneration layout
involves 5 clear steps. Depending on the nature of your facility and the performance objectives of a CHP system being considered, each of the 5 steps can be performed by the facility’s manager or agent, consultants, or vendors.
T The process for evaluating whether
CHP makes sense at a facility (and thus merits a Level 1 Feasibility Analysis) begins with an assessment of technical potential and continues with an initial assessment of cost-effectiveness. Technical potential CHP can be used in applications which have significant and coincident power and thermal loads. For optimal cost- effectiveness, CHP systems typically are designed and sized to meet a facility's year-round baseload thermal demand, which can include steam, hot water, chilled water, process heat, refrigeration, and dehumidification. CHP systems generate electricity
Do we have the necessary technology in the UK - and do we use it? “We have it in certain places, but it’s not as common as it should be. The heat capture technology exists and is actually well established in countries like Denmark and the Netherlands. CHP plants can be as much as 95% efficient. Compare this figure to the old fashioned power plants we presently use, which are, on average, only 38% efficient.” What kind of real potential has CHP got to save energy in the UK today? “The potential is simply enormous - and we’ve hardly scratched the surface. On industrial sites where huge quantities of heat are needed, CHP plants can be similarly large. For example, the Immingham CHP plant, supplying two refineries in Humberside with heat, steam and power, was expanded in late 2009 to reach the same electricity generating capacity as the UK's flagship nuclear power station, Sizewell B. “The key thing to remember is that combined heat and power (CHP) is a highly
efficient process which both captures and utilises the heat which is a by-product of the electricity generation process. By generating heat and power simultaneously, CHP can reduce carbon emissions by up to 30% compared to the separate means of conventional generation via a boiler and power station. The heat generated during this process is supplied to an appropriately matched heat demand that would otherwise be met by a conventional boiler.

and use waste heat to meet some or all of these demands. CHP can be a strong technical fit in many different types and sizes of facilities, including: * Commercial buildings - hotels and casinos, airports, high-tech campuses, large office buildings, nursing homes * Residential - blocks of flats, co-ops, apartments, planned communities * Institutions - colleges and universities, hospitals, prisons, military bases * Municipal - district energy systems, wastewater treatment facilities &
aking a CHP project from conception to completion
Cost-effectiveness potential The main benefits of CHP for the user are reduced energy costs and increased energy reliability. The cost-effectiveness potential of CHP depends on: * The cost differential between avoided electricity purchases and fuel used by the CHP system * Capital costs
* Operating and maintenance costs * Planned new construction or other circumstances (such as equipment replacement needs) which may necessitate invest- ments in new equipment such as HVAC or boilers * The value to the facility of improved electricity-supply reliability * Utility policies at the local, state, and federal level (e. g., utility interconnection require- ments, standby/backup charges, and the potential compensation for electricity exports to the grid) Estimated cost-effectiveness will be determined with more certainty and precision as part of the level 1 and level 2 feasibility analyses. If the project shows technical potential and passes a cost- effectiveness screen, the next step is to review the results with key decision makers. This is the point where you would determine how a project would be financed, its cash-flow impacts, and how it would fit into an organisation's capital spending plans. If the results of this review are positive, proceed to a Level 1 Feasibility Analysis.
