The future can be lit with energy savings

We believe that ideas make the world a better place. We know that one bright idea can change the usual course of everyday things. By developing an advanced power solution today, Spark Energy Eco (SEE) defines the nature of electricity in the present and in the future. Economic situation in the World often accelerates a technological progress and creates a steady demand for highly efficient innovative products and technologies.

One of the promising directions for developing renewable energy is the Closed-cycle hydroelectric plant (CCHP). Spark Energy Eco offers stationary CCHP installations for inclusion in the power supply grid system.

The frequency of the energy produced in Hz is not subject to fluctuations and jumps thereby, it enters the consumer in a stable and pure form. The use of CCHP energy helps to solve many problems of energy supply to such facilities as country houses and industrial facilities of various capacities and also to gain independence from local energy supply organisations, thereby ensuring a significant reduction in costs.

Sustainability

The main source of CCHP energy is a liquid that serves as an engine for generating environmentally friendly electricity in a confined space. Internal energy consumption is spent on the operation of pumps and auxiliary equipment in the amount of no more than 3-5% of the total capacity of the CCHP. Thus, the efficiency of CCHP is more than 95% of the design capacity.

Principal of operation

The basic principle of hydropower is that water is piped from a certain level to a lower level, with the resulting water pressure being used to do work. If the water pressure is allowed to move a mechanical component, then that movement involves the conversion of the potential energy of the water into mechanical energy. Hydro turbines convert water pressure into mechanical shaft power, which is used to drive an electricity generator.

CCHP can be connected to the central power system or used autonomously, i.e. without connection to a grid.

The turbine and generator outputs the specified voltage to the auxiliary equipment (voltage controller, storage batteries) and converts electricity for the consumer 220-380V, 50 Hz three-phase current. If the CCHP produces more electricity than is necessary for this facility, the excess can be sold to the central grid. Thanks to modern controllers technologies, switching takes place both in manual mode and automatically, according to a given program. The capacity of CCHP used varies from 30 to 25,000 kW, and can be used in an economical mode depending on the amount of own energy consumed.

Advantages

Distinctive features of the proposed CCHP:
• complete independence from fossil energy sources (petroleum products, gas, coal, etc.), a high capacity factor, i.e. time generating power throughout the year;
• environmental friendly (there is CO2 emission);
• absence of sound and magnetic radiation due to the special shape of the mechanical part;
• production of industrial-quality electric power of both direct and alternating current (voltage 220-380 W, frequency 50Hz);
• it is a long-lasting and robust technology; systems can readily be engineered to last for 50 years or more, low maintenance costs;
• the rotation speed of the turbine and generator is limited: 150-600 rpm;
• the electric generator is located at the bottom of the installation, which makes it easy to install and maintain;
• the high efficiency of the installation is achieved due to the minimum internal power supply needs of up to 5% of the rated power, more than 95% of the power is given to the consumer;
• requires minimal space;
• scalability according to the customer energy requirements;
• has auxiliary production of thermal energy in the amount of up to 7% of the rated capacity.

CCHP offers short payback period and it is required much smaller space to complete installation compared to other renewable solutions and has minimum visual impact on their surrounding environment. In a suitable location small-scale hydropower is one of the most cost-effective and reliable of the renewable energy technologies.
