Challenges of CHP Sizing

There is always a tendency for CHP to be oversized, especially when the selection is based on thermal output. This leads to reductions in annual running time, and considerable loss of financial saving for the client. In extreme cases it can lead to physical damage due to excessive shutdowns and failures.

CHP versus other renewable energy sources

When there is such a range of energy-saving and carbon reduction technologies available, it may often be difficult to decide amongst them. It is true to say that each individual technology should be considered on its own merits, and the services of a specialist consultant may be required in order to manage the performance and financial assessments that are part of this process.

What is an AMF panel?

Automatic mains failure (AMF) panels, often referred to as automatic transfer switch (ATS) panels, make the power switch to emergency standby generators in the event of a significant loss of mains power or total blackout. Without AMF panels, generators need to be operated manually and that can mean lost data, potential damage to electrical equipment, and huge amounts of disruption. Read more »

What is CHP?

Combined Heat and Power (CHP) is the simultaneous production of heat and electricity from a single fuel source, usually at the point of use.

With a CHP system a fuel (usually natural gas) is used to drive a reciprocating engine, delivering electricity from the alternator. At the same time the heat produced by the engine working, is captured from various sources (for example from the exhaust system and engine cooling circuits) to produce hot water. On some models heat is also recovered from the alternator and engine oil, further increasing efficiency.
Typically a CHP will produce up to twice the amount of heat energy as the electricity it generates. Read more »

What is G59?

G59 Embedded Generator Regulations

G59 is the regulation surrounding the connection of any form of generator device to run ‘in parallel’ or ‘synchronised’ with the mains electrical utility grid (National Grid).  The regulation has its roots in Ofgem rules, and is administered as the Energy Networks Association Engineering Recommendation G59/2-1 “Recommendations for the connection of generating plant to the Distribution System of Licensed Distribution Network Operators – Amendment 1”.

This is relevant for all power generation, including combined heat and power units as well as generators being used for peak-lopping, or grid parallel use, greater than 16A per phase.  For anything below this the Engineering recommendation G83/1-1 applies. Read more »

4 common misconceptions on G59 regulations

In years of doing projects with G59 protection shentongroup have often come across some popular myths, so we seek to dispel them here:-

I don’t need G59 Protection unless I intend to export power to the grid”.

Wrong.  If you have any form of generator where the output is connected to the electrical systems in your building, and thus to the grid, you must protect it with a G59 relay device.
