Power + Energy Associates provides Independent Engineering Services to the Power Generation Industry worldwide as well as providing
services in the field of energy for industry. The consultancy is soundly based on many
years of experience encompassing all aspects of thermal power plant design, development,
procurement, construction, commissioning through to operation and maintenance.
We apply expertise and knowledge to a wide range of activities including Project
Development, Concept and Feasibility. Assignments advise on Economic Analysis, Due
Diligence, Specification, Procurement, Agreements, Site Investigations, Reports, Fuel
Supply, Plant Layout, Steam Cycle Design, Combined Cycle Technology, Cogeneration, CHP for
Industry, Steam and Gas Turbines, Steam Generators and Boilers, Heat Recovery, Process
Steam and Performance Assessment. Our work spans activities starting from initial
investigation and concept, negotiating and preparing key agreements up to project
implementation.
P+EA specialises in providing expertise to meet the individual needs of power and energy
industry clients. Services are provided to project developers, banks, independent power
producers, process industries, consulting organisations, major equipment suppliers and EPC
contractors amongst others. This service is unbiased and independent of suppliers and
contractors. Typical assignments may include the following tasks:
- Advising Project Owners and Developers
- Due Diligence/ Acquisition Studies
- Project Development Services
- Plant Selection and Project Costs
- Design Concept and Feasibility
- Independent Construction Monitoring
- Site Inspections and Investigations
- Reporting to Sponsors / Owners
- Formal Presentation of Findings
- Providing Reports and Recommendations
Some examples of our activities:
Combined Cycle Expansion Study . Review of an
existing CCGT plant and the technical case to proceed with an expansion with additional
gas turbines, heat recovery steam generators and associated plant. The study considered
feasibility and the need to take account of various systems limitations. The comments
provided included plant operating range, steam turbine, condenser, ambient considerations
and plant layout to accommodate the new installations.
Review carried out of CARMA published
CO2 Emissions Data on behalf of a CCGT plant owner.
The review examined actual plant CO2 emissions and compared these to those on web site.
Comments were also given on reliability of published figures. A recommendation was given
on the estimated annual CO2 emissions and Intensity together with relationship to plant
annual average sent out efficiency.
Technical review of Competent Person Report for a 300MWe lignite fired power plant
as part of the development of a major resource in South Asia. A variety of technologies
were reviewed and the most appropriate available technology for unit sizes of 300MWe
reported. It was confirmed that the technology is commercially proven in the considered
output range.
Together with investor representatives carried out a Due Diligence Inspection in
Eastern Europe of a conventional coal and bio-fuel fired Power Station and District
Heating Plant. The resulting report included a detailed assessment of the condition of the
power station and other facilities, life expectancy and the continued operation of these
facilities. An assessment of the eventual decommissioning costs was given.
Validation of Boiler Efficiency
and Performance Guarantees following NOx Abatement
Modifications at a major UK coal fired power station. Independent review made of the
results of tests before and after modification out to validate the performance. Each
boiler tested at two loads on oil only, three loads on coal only and also on coal/ oil.
Tests carried out in accordance with test procedures and PTC4 and the results checked
using both PTC4 and BS EN 12952 Part 15. Comparison to the contractor reports and
independent results reported.
P+EA were assigned to visit the premises of a UK process developer to review Laboratory Operations and make recommendations for the future development of their
laboratories. This review considered the testing and analysis aspects of raw materials
received for testing according to a patented process for pelletisation, control of the
process and the quality parameters.
Investigation carried out into Fuel
Conversion Efficiency at a major European Lignite
Fired Thermal Plant over two-year period. The entire process was examined and extensive
discussions carried out to gain a comprehensive understanding of the plant activities and
procedures affecting Fuel Conversion. This involved examining the fuel conversion process
from start to finish, fuel delivery from delivery point to the boilers, combustion,
turbine performance, power generation, auxiliary power consumption and power export. Based
on our recommendations a series of heat rate tests were carried out under our supervision.
A report has been issued together with recommendations for improving the plant operational
efficiency and fuel conversion, which are being implemented.
Engaged by power off-takers within the Canadian regulated power market in order to
assist them in responding to the State Utility Air Emissions Strategy. This
involved reviewing and commenting on technical submissions from the Utility and other
Stakeholders to the Electricity
Regulator. Reports were provided by P+EA on
available SO2 emissions reduction technologies from large coal fired units and
flue gas desulphurisation processes. Technical and economic comparisons were given and the
estimated reductions in SO2 emissions provided. A separate P+EA report covered
the available technologies to reduce NOx emissions, proposed Optimising Combustion and
installation of a Low NOx Burner system then further NOx reductions by either Reburn or SNCR/ SCR to
be considered. Subsequently the first two steps were implemented and following completion
of the modifications tests carried out and we were asked to review and comment on the
Contractor reports.
Further examples of our activities can be found on the P+EA Experience page.
