Summary
of Enron's Energy Major Business Process
EnronOnline (EOL). EOL,
a system providing the trader with an ability to set and control a range
of bids/asks and market positions without having to resort to phone calls,
and real-time access to energy markets using the Internet. Enron Online
(EOL) is a web-based deal capture system to initiate and complete transactions
in a variety of commodities, including power and natural gas. These transactions
included both the purchase and sale of commodities. EOL
supported over 8,000 transactions/day, totaling about $3 billion of energy
products daily.
- Stack
Manager: The Stack Manager is a special
client-server program written in Visual Basic that allowed an Enron trader
to create a stack of prices at different volumes for a specific product,
and save it to the EOL database.
- The
Product Manager is a specialized client-server
program written in Visual Basic that allowed Enron Online product managers
to create product types and, based on the product types, create products
for trading on EOL.
EOL worked in tandem
with front-office tools, such as Sitara for physical
gas and EnPower, which provided data management
capabilities for decision support, such as portfolio management, position
management and risk management. Trade information flowed through these
systems along multiple paths, depending on the type of trade, whether gas
or power, physical or financial, etc
- EnPower- EnPower is the central repository for Electric power trading
data. EnPower'sdata storage mechanism consists
primarily of relational database tables within Oracle. The EnPower database consists of over 550 relational tables,
which contain about 7,900 individual non-unique columns of information. Some
of the tables contain over a million rows of information.
- Sitara- The Sitara system
was used to capture physical gas deals. Physical gas deals that originated
in EOL would also flow into Sitara. Sitara's data storage mechanism consists primarily of relational database
tables within Oracle. The primary Sitara database
consists of 122 tables with over 1000 data columns. A number of the tables
contain over two million rows of data, with some containing over 4 million
rows.
- TAGG/ERMS - ERMS is the Energy Risk Management System. It contains transaction information
pertaining to physical and financial deals involving gas, financial deals
involving power, and physical and financial deals involving all other commodities. Functions
provided by ERMS include: risk management, valuation, position management,
curve management for rates/pricing, and management reporting. TAGG/ERMS
is built on the Oracle database.
- Unify - Unify is the deal settlement processing system within the Enron trade infrastructure. Unify
is built on a Microsoft SQL Server 8.0 database running on a Windows
2000 server. Each Unify database has about 490 tables, with over 3500
non-unique columns. There are a number of tables with over a million
rows.
- RisktRAC - RisktRAC is the global risk aggregation system. Some
of the inputs into RisktRAC are: valued deals
from EnPower, MTM (mark to market) data, open
position data, and curve data from ERMS. RisktRAC has about 179 tables with over 4900 non-unique columns. A
number of tables contain over 10 million rows of data, with some close
to 200 million rows
- CPR - The Cash Position
Reporting tool works in conjunction with Sitara and
allows traders read-only access to data in Sitara. This
is to assist the traders in completing their position reporting with regard
to gas deals.
