Energy for the future Slovenské elektrárne

Each trak®LiOn battery module from Hoppecke contains a specially developed battery management system. The battery management system integrated in each battery module allows for communication with other modules in the battery system and with the connected load via CAN-bus (CAN2x).

All factors relevant to the system, such as state of charge, state of function, are transmitted to the customer.

Reserve power products

Hoppecke’s H2.power is just one example of the company’s range of reserve power products. H2.power is a modular hydrogen fuel cell system for backup energy supplies in different applications (e.g. IT/Telecom, Security and government sectors, transportation etc.). 19” and 23” modules can be easily integrated in cabinets or racks together with other equipment such as batteries, or converters. H2.power is a safe and reliable power supply with no emissions beside warm air and water.

Another product in the reserve power range is the Hoppecke sun.power pack, Hoppecke’s energy storage solution to optimise direct photovoltaic consumption.

Today, everybody is talking about sustainable energy. However, the price for self-produced photovoltaic energy which is fed into the power network is dropping rapidly, while at the same time, the energy price of the electricity suppliers is constantly increasing. For many private households and businesses, these are two important reasons to use their own solar energy directly.

Since the generation and consumption of photovoltaic energy are not synchronised, battery systems are needed to store the photovoltaic energy for later use. Hoppecke’s sun.power pack is such a storage solution: it stores solar energy temporarily in order to use it at specified times. Even in the event of a power failure, customers are on the safe side. The battery system immediately provides the required energy.

Special power products

In 1983, Hoppecke introduced a nickel-cadmium battery, which is unique world-wide to date for its fibre structure technology (FNC® technology.) This dense three-dimensional fleece structure was originally designed for such demanding applications as aviation and aerospace and electric and hybrid vehicles.

Today, Hoppecke continues to develop special power products that allow high to very high currents, for the railway industry and the aviation and aerospace industries. n

ENERGY FOR THE FUTURE

Slovenské elektrárne is the biggest electricity provider in Slovakia with 82 per cent of the country’s generation market. It is the main supplier of electricity for the three biggest regional distribution companies in Slovakia and also supplies electricity to large businesses. What challenges does the company face in today’s complex energy market? Romana Moares reports.

Slovenské elektrárne, a.s. is a company whose core business is the production and sale of electricity. In terms of available installed capacity it is the largest power generating company in Slovakia and the second largest in central and eastern Europe. It also generates and sells heat, and provides ancillary services to the power grid. It has an ideal production mix - nuclear, water, fossil as well as renewable resources. The company has 5739 MWe of gross capacity in 34 hydro electric, two nuclear, two thermoelectric and two photovoltaic plants.

The company’s goal has always been the safe, reliable, efficient and competitive production, sale and trade of electricity and heat. It is also concerned with the safe handling of radioactive waste and spent nuclear fuel, with permanent lowering of the negative environmental impacts of production processes.
