Batteries vs Thermal Stores

Assisting one of our energyPRO users modelling a newbuild multi-residential district heating project where the scheme includes PV, a ground source heat pump, electric batteries and a thermal store brought into sharp focus for me the relative cost benefits of thermal storage vs electric storage.

Ofgem’s Proposal to Remove Triad Payments from Embedded Generators

If you’ve been involved in any CHP/DH feasibility studies you will probably know that many projects are quite marginal. The high cost of building a heat network that has to compete with an existing gas network means that that very … Continue reading

Electricity “Foregone”- Maximising CHP’s Virtual COP

In the Introduction to the government’s Heat Strategy (The Future of Heating), the chief Scientific Advisor to DECC, Professor MacKay, makes the point that waste heat from power generation isn’t free. When you make use of the waste heat for … Continue reading

Nuclear CHP: why settle for less?

An intriguing title for a blog I hope you’ll agree. Firstly let me say that I’m not a fan of nuclear power. I’m concerned about the safety, the cost, the waste disposal issues and the fact that it’s not renewable. … Continue reading

Is Consumption Modelling inherently superior to Production Modelling?

The point is continually made that pure consumption modelling, whilst being possibly more difficult to do than a mixed approach or pure production approach, is inherently superior. I would like to question this. Continue reading
