Context

Yelo’s production facility in Warwickshire processes UK-grown, farm-assured rapeseed for vegetable oil and animal feed. Endress+Hauser provided heat metering technologies and expertise to help the food producer comply with regulations for its new CHP plant.

Challenge

In 2016–17, a biomass-fuelled combined heat and power (CHP) plant was constructed to provide energy to Yelo’s rapeseed processing facility near Stratford-upon-Avon in Warwickshire. Endress+Hauser was commissioned by the project developers to provide consultancy services surrounding the Renewable Heat Incentive (RHI), a government environmental programme that provides financial support to increase the deployment of renewable heat systems by businesses. Due to Endress+Hauser’s expertise in heat metering, it was also asked to provide metering, data acquisition.

Solution

The CHP plant comprises an 11.4MW biomass thermal oil heater providing heat to a Turboden Organic Rankine Cycle (ORC) unit. The thermal oil heat is measured with an Endress+Hauser Prowirl 200 Vortex flowmeter in combination with an RH33 heat calculator. A hot water supply from the ORC condenser system to the processing plant is metered with an Endress+Hauser Promag 50 flowmeter plus an RH33. After passing through the ORC unit, the rejected thermal oil is passed through a heat recovery steam generator, providing 7 bar saturated steam to the process. This is metered with a combination of Prowirl and Promag technologies in conjunction with RH33 heat calculators. An RSG45 data manager calculates the heat produced in the biomass boiler during two different modes of operation: one when the system is running as a full CHP plant; and one when the ORC system is shut down and the plant is configured as a standalone biomass heat source.

As well as providing RHI-compliant metering for the CHP plant, Endress+Hauser produced an Independent Report on Metering Arrangement (IRMA), the Ofgem report required for RHI accreditation. This requires the assessment of all heat losses from external piping, schematics detailing the meter and plant arrangement and the determination of an eligible heat output payment formula. “Our metering regime was not straightforward and Endress+Hauser brought both a deep knowledge of the Ofgem metering requirements and a technical understanding of our scheme,” remarked Yelo’s Operations Director Carlo Matos.

Heat and electricity metering data is now collected from a gateway and processed using a cloud-based data management and reporting platform. This platform provides all the data for monthly Ofgem reporting and tracks RO power and RHI heat revenue. After helping Yelo to achieve RHI accreditation, Endress+Hauser now provides a service contract to maintain and check the performance of the meters, which is an obligation under the RHI regulations.

Outcome

As experts in heat metering, Endress+Hauser is the ideal partner for biomass CHP projects. As well as having an in-depth understanding of the regulations and an unrivalled instrumentation portfolio, the company has a proven track record of delivering consultancy services that help companies to save energy, reduce costs and improve their environmental credentials.

Carlo concludes, “We now have a world-class energy reporting system that takes all the stress out of the myriad of reporting requirements, both to shareholders and to Ofgem.”
