Damas Power is a comprehensive electricity and heat generation management system built on the Damas platform. It has been designed specifically to meet the needs of conventional generating facility operators, operating in open energy market environments.
The major value added provided by Damas Power lies in its full coverage of business-technical processes associated particularly with combined heat and power generation. Damas Power supports generation scheduling in multiple time cycles (year, month, day, intraday), use of reserves to provide ancillary services, including operation scheduling and communication with the transmission system operator, as well as sales support and operation balancing based on evaluation of metered values.
Why Damas Power
From the business perspective, Damas Power consists of the following modules (see Fig. 1):
Fig. 1 – Basic Modules of Damas Power
Full technological and operational data for each generating facility is a prerequisite for proper operation scheduling, management, and evaluation. The term major generating facility includes boilers, turbine-generators, pressure limiting stations, and other facilities.
The Generation Resources module provides storage and administration of such data. In process terms, there are two types of stored data:

The Scheduling module allows you to generate a financial balance sheet for power plant / heating plant operation for a calendar year, later refining it in short time periods.
Calculations of possible variants of electricity (heat) supply, output reserves for other purposes (e.g. output reserve for ancillary services provided to the transmission system operator), and consumption of raw materials are based on provided data on compulsory (contractual) electricity / heat generation. The system calculates financial indicators, including revenues and costs of major raw materials consumed during operation.
The Scheduling module may include multiple business schedules for a single period; however, only one of these is flagged as active and propagated to other modules (Sales, Ancillary Services, and Balancing). To produce a business schedule, the following inputs are expected:
Scheduling outputs include mainly scheduled volumes of electricity/heat supply and revenues from their sales. Besides the revenues, the generation cost is also evaluated, including both primary costs of fuel and accessory costs (environment, water, chemicals).
Outputs also include operation schedules for generating facilities, with a breakdown to boiler rooms and engine rooms.

The Sales module is used to manage and keep records of the electricity generation schedule for a performance day. The sales process includes purchase by a single buyer within a balancing group; advanced functions (contract administration, short-term markets) are available in Damas Trade.
The electricity generation schedule is developed and gradually refined in the following phases:
The module also provides basic evaluation of both scheduled and actual electricity supply, along with calculation of financial data for invoicing. On the next work day after the performance day, the scheduled electricity supply is compared against the actual electricity supply, based on metered values, and the obtained values are transformed to the financial result of the operation.

The Ancillary Services module covers all business processes necessary to provide ancillary services (AnS) to cover the needs of the transmission system operator (TSO). The module is divided into the following parts:
Certifications deal with storage of documents proving the technical eligibility to provide ancillary services at operated generation sources.
AnS Sales provides support for participation in tenders, or in the day-ahead AnS market. Based on the current operation schedule, stored sales values, and demand by the TSO, the system generates bids for providing of AnS. When the tender (day-ahead market) is closed, any accepted bids are automatically reflected in AnS Contracts.
For AnS activation, shadow calculation of the amount of the realized balancing energy and technical evaluation of the generation sources providing the AnS is performed in Evaluation, based on data from the Metering module. The computed value is verified against values published by the TSO and the system automatically generates claims for any mismatches. In the monthly mode, total payments are evaluated on a monthly basis, with invoicing data passed to the accounting system.
The Balancing module provides multiple views of Generation evaluation. It contains both data for internal purposes and data submitted to various authorities (ERO, MOE, MIT).
The balancing process provides company executives with information on the health and operation progress for each facility, group of facilities, and the plant as a whole. At the same time, it evaluates the performance of the financial and business plan.
The Balancing module is divided into the following areas:

The balancing process is performed for various fixed time intervals (day, month, quarter, or year), as well as for a rolling interval (a continuous interval of days).
Energy Balancing is an essential tool used to monitor electricity and heat generation in plants and evaluate the operation economy. Outputs of the process include the electricity generation and supply balance, the heat generation and supply balance, the fuel consumption balance, and the summary overview of normalised operation parameters.
Operation monitoring is a part of Energy Balancing. In this section, media operating flows are monitored at a detailed level (all facilities, not only boilers, turbine generators, steam piping...), tracking multiple parameters (cooling fluid, fuel ...). This area also includes evaluation of self-consumption of electricity, consumption of operational media (water, steam), tracking of specific indicators and standards, and more.
Environmental Management provides important output reports concerning environmental management of a heating plant. It provides overviews on materials and substances consumed by the production unit (fuel) and produced during its operation (CO2).
Water Management Balance performs evaluation of the total consumption of water and consumption of the chemicals used to prepare and purify water for operational use.
For executive purposes, all evaluated data is conveniently aggregated and linked to the Economic and Trade Balance, which provides a comprehensible link between the obtained operational data and the financial and business plan.

The Metering module is used to store data on (hourly, daily, and monthly) readouts, health of measuring instruments, replacement of measuring instruments, and other parameters.
Therefore, the module consists of two areas:
It is possible to enter instrument readouts into the system manually via its graphical interface, or an automated interface to an external measuring system can be integrated.
