ANNUAL REPORT - HSE

Long-term contracts and
day-ahead market
The bulk of the sales were generated through longterm
contracts. The trading in day-ahead markets was
carried out to match contractual obligations with the
production capacities of HSE Group companies and to
optimise the company’s portfolio and take advantage
of market opportunities. Electricity surpluses generated
at the time of high water levels and availability
of additional electricity produced during periods when
market price exceeded the cost of extra production
were sold in day-ahead markets.
