Bosch claims it has developed an energy management system for optimising electrical and thermal energy consumption from solar power systems, which the company will launch at this year’s Intersolar exhibition and conference.

Bosch refers to the new product as an “intelligent networked solution” which it will launch through subsidiary Bosch Power Tec. It can combine the use of photovoltaic arrays with a heat pump, with the whole network controlled by a Bosch e.Control control unit. The solution is aimed at residential users.

According to Bosch this means that if there is sufficient solar irradiation, electricity generated by the PV system can drive the heat pump, while the system can “considerably increase” how much on-site generated power can be used. The systems can also be combined with energy storage as a further option to maximise self-consumption.

The e.Control unit connects to the householder’s electricity meter, monitoring

Suddenly, we have seen a spate of “death spiral” talk about electric utilities. Grid parity — through lowered costs — is supposedly triggering this decline. Homes are expected to defect from the grid, or maintain a limited link with it for reliability, thanks to solar panels backed up by batteries and gas-generators.

AHMEDABAD: At a time when 30% of the recent capacity addition in Indian power generation sector has been made through use of Chinese equipments, the inefficiency of the installed equipments has become a major cause of concern. If projection made by one of the leading players in the Indian power sector is anything to go by, 1% inefficiency in the operations of these equipment, with collective capacity of 18,000 MW, for their entire life span of 30 years, can cost the country Rs 1 lakh crore. At a press conference organized by Indian Electrical & Electronics Manufacturers Association (IEEMA) in city on Monday, the stakeholders of the power equipment manufacturing industry urged the government to take some major initiatives to spur the growth of the industry and the power generation sector as well, which is very crucial for the economic growth.

According to reports, after dilly-dallying for nearly five years, promoters of National Power Exchange have decided to wind up the company. National Power Exchange is jointly promoted by NTPC, PFC and NHPC and private sector Tata Consultancy Services. Following the promoters’ decision, electricity regulator CERC has withdrawn the permission granted to the exchange for starting power trading business. At present, there are two power bourses in the country, Indian Energy Exchange (IEX) and Power Exchange India. The Central Electricity Regulatory Commission (CERC) had given its approval to National Power Exchange for operating a bourse way back in July, 2009. The promoters, however, last month decided to wind up the company. In their meeting on March 21, promoters had recommended voluntary winding up of the company. On the same day, the bourse’s board decided not to renew the licence for setting up the operation of power exchange beyond March 31. The regulator was informed

Six gas-based power projects in East Godavari district with a combined capacity of 5,000 MW have shut down their units due to acute shortage of gas. One of the projects has even started selling gas turbines and other units from its plant. The government, on its part, has said that gas supply is possible only after July. "We don't know what policy the next government will adopt on gas supply to private power plants. It till take at least two months to put all private power plants in the region on track if we start the gas supply by May-end," says G. Satyanarayana, General Manager, Gas Authority of India Limited (GAIL). The idle plants due to shortage of gas are GMR's Vemagiri (850 mw), GVK's Jegurupadu Extension (440 mw) and Gauthami (250 mw), Konaseema Gas Power (750 mw) Reliance (450 mw) and Spectrum (450 mw).
