Commercially validated! ELENCON’s energy management system effectiveness measured at Five pilot sites with over 30% in cost savings.
The innovative energy management technology that has been developed by ELENCON, one of Horizon’s portfolio companies, that has already been implemented in 6 pilot sites in Israel, enables significant reduction in energy consumption in commercial and office buildings with zero out-of-pocket expense to the end users.
The effectiveness and sustained performance of ELENCON’s Air Condition Energy Management system is being currently validated in four current installations, with actual data demonstrating above 30% in cost saving.
Notable results include: First installation in ‘Holon Institute of Technology’ with 160 cooling-tons, showing a very stable saving in energy cost at around 40%.
An installation in ‘Hasharon Hospital’, with a total of 580 cooling-tons and including special designs for their unique requirements is currently demonstrating a 40% increase in cost savings.
An additional installation in ‘Rotem Industrial Park’ with 250 cooling-tons, with 25% savings. A pilot site at Afcon Control Systems office building, with 680 cooling-tons, OPC interface with the existing building management system, also reaching impressive cuts of 40% in costs.
By the end of 2015, it is expected that the system will be installed in an additional four sites.
ELENCON’s novel Air Conditioning Energy Management system focuses on defining and controlling chiller set-point according to various parameters and dynamic pricing (DP), without affecting room temperature, while achieving the most effective and cost efficient use of energy.
With the ever-growing global warming conditions, the global energy market is and will continue to struggle with peak demands, rates, and business continuity. HVAC is contributing over 50% of office buildings’ energy expenses, causing area peak demands and shortages. The need for energy efficiency has been intensifying with little to no effective solutions yet.
SunBoost is heading towards first Pilots for its novel Greenhouses application
SunBoost, a technological venture currently nurtured at Horizon GreenTech Ventures, is aiming to enter the PV global market with a revolutionary and novel optical collector, “Booster”, intended for conventional ground and flat roof PV installations, and for Combined GreenHouse-PV disruptive application. SunBoost has installed its first 50kw pilot plant, already demonstrating an average annual 10% – 15% increase in annual electricity production, and expected ROI of 4-5 years.
SunBoost’s, patent protected, disruptive technology enables installation of PV systems on-top of greenhouses without compromising agriculture yields. This is achieved by using unique and innovative designed optical glass boosters. Boosters and PV panels are positioned to collect light when it is in excess and to allow the sun into the greenhouse when it is required for the crops. The system enables for the first time combining PV and greenhouse agriculture which in principle are competing for the same solar resource. Tens of thousands of hectares of greenhouses are erected every year, forming a huge market in which SunBoost will have a definitive edge over conventional greenhouses.
Additional vast market opportunity targeted by the booster technology is the conventional PV installations, either ground or rooftop installations, increasing their output by up to 15%. This is done by placing the boosters in spaces between rows of PV panels and directing “lost” sunlight from the space onto adjacent PV panels.
The boosters are optical panels that direct light falling between rows of PV panels, onto the PV panels, without exceeding allowed peak power (soft boosting). The boosters’ design overcomes challenges that prevent the use of mirrors for this task.
Can electrical grid managers finally get a good night’s sleep?
Synvertec, a new venture incubated within the Horizon GreenTech Ventures platform, is a developer of advanced control modules for inverters. The company is developing a technology that will allow the feeding of renewable energy to electrical grids, without compromising the grid stability. The first prototype of the system is presently being tested at Synvertec’s labs. The Synchroverter control module was designed to fit small, medium and large inverters, aiming to remove existing barriers and significantly increase the use of renewable energy without compromising the quality of electricity.
Clean energy is one of today’s most important social, industrial, environmental and business challenges. Significant efforts invested by governments and businesses are currently underway to greatly increase the penetration of renewable energy systems on local and regional utility grids to achieve goals related to emission reduction, energy independence, and improved infrastructure reliability. The infrastructure reliability in electricity grids is defined by low fluctuations of the voltage and the frequency. Traditionally, these are stabilized by a combination of the rotational inertia (rotating mass) of synchronous power generators in the grid and a control algorithm acting on the rotational speed of a number of major synchronous power generators.
When renewable energy penetration reaches high enough levels (e.g., 5% to 20% of total generation), and many non-synchronous generation units replace a significant part of the synchronous power generation capacity, the variation in the rotational speed of the synchronous generators, due to changes in their net load, will become much higher than those experienced presently. This will causes large fluctuations in grid voltage and power factors that may cause an unstable grid that can wreak havoc on utility operations and on load-side equipment. Stated simply, fluctuations on this scale will not be allowed. New regulations are being formed across the globe that will require inverters to take part in the regulation of voltage and frequency.
Based on a patented technology developed in Liverpool and Tel-Aviv universities, Synvertec has met the challenge of developing enabling technologies that will facilitate the connection of renewable energy sources to the grid. The control algorithm of Synvertec mimics the DC power source (e.g. PV field) to a self synchronizing generator, so that the power source is actively participating in the grid stabilization, reducing the load on the synchronous generators and does not change the proven operation of the grid controls. The first prototype of the system is presently being tested at the Synvertec’s labs, with the goal to build a network of self synchronizing inverters within six months. Synvertec’s control module was designed to fit small (< 10KW), medium and large (> 250 KW) inverters. The company strongly believes that this technology will remove existing barriers and significantly increase the use of renewable energy without compromising the quality of electricity
