O&M Circle MSEDCL.

Sub :- Exemption of Electricity Duty to Open Access consumers who are exempted to pay Electricity Duty.

Ref :- 1) Maharashtra Electricity Duty Act. 2016 amended vide GoM Resolution dt. 08.08.16

  • GOM Notification 31.08.2016.
  • Office Note P-Com/Accts/ED 1341 dt. 02.11.2016

In connection with above that as per GoM resolution dt. 08.08.16 the electricity duty has been charged on the consumption wef Sept.2016 onwards to all open access consumers as above except consumers of Vidahabha & Marathwada region.

Thereafter, MSEDCL received several representations from OA consumers and RE generators who are already exempted for payment of Electricity Duty as per the eligibility certificate granted by GoM.

As such, it has been decided that, the MSEDCL will stop levying the electricity duty to such OA consumers and RE generators who are exempted from making payment of Electricity Duty in bills issued and being issued from December 2016 onwards, till further instructions from GoM/Hon’ble High Court Mumbai in this matter

Accordingly, the instructions has been issued to IT for not levying the duty to exempted consumers with instructions to credit amount of Electricity Duty recovered from such consumers from the month of Sept. 2016 to NoV.2016 & Dec.16 in Jan.2016 bill. Now some of the bills are already issued and they have already made the payment of their bills. However, if any consumer willing to pay the bill excluding the amount of electricity duty then such payment may be accepted as per revised bill from IT for the month of Dec.16. It is directed to not to take any corrosive action on such OA consumers who have not paid Electricity duty amount on OA quantum.

If any of such consumer who has made payment of bills excluding Electricity Duty of OA quantum and is eligible prompt payment discount & related load factor incentive will get his anticipated benefit and detail instructions are already given to IT in this regard. It will be applicable to only Electricity Duty exempted consumers.

Further, as per the RE Policy of the Government of Maharashtra RE generators are under exemption to pay the electricity duty for the period of 10 years as per GoM notification. As such the details of such RE generators are required to update in the system for extending them the benefit of GoM’s policy.

You are therefore requested to take note of above and inform the details of date of commissioning of RE generators of all open access consumer under your circle so that their exemption period can be fed to system and RE generators already completed 10 years can be identified for charging the electricity duty.

Power loss due to soiling on solar panel: A review

The power output delivered from a photovoltaic module highly depends on the amount of irradiance, which reaches the solar cells.

Many factors determine the ideal output or optimum yield in a photovoltaic module.

However, the environment is one of the contributing parameters which directly affect the photovoltaic performance. The authors review and evaluate key contributions to the understanding, performance effects, and mitigation of power loss due to soiling on a solar panel. Electrical characteristics of PV (Voltage and current) are discussed with respect to shading due to soiling. Shading due to soiling is divided in two categories, namely, soft shading such as air pollution, and hard shading which occurs when a solid such as accumulated dust blocks the sunlight.

The result shows that soft shading affects the current provided by the PV module, but the voltage remains the same. In hard shading, the performance of the PV module depends on whether some cells are shaded or all cells of the PV module are shaded. If some cells are shaded, then as long as the unshaded cells receive solar irradiance, there will be some output although there will be a decrease in the voltage output of the PV module. This study also present a few cleaning method to prevent from dust accumulation on the surface of solar arrays.

Solar nearly level with wind and out-competing fossil fuels in developing countries – BNEF

Average capital expenditure (capex) for PV projects in developing countries during 2015 stood at US$2.15 million/MW, rapidly approaching average wind capex of US$2.02 million/MW. Credit: BNEF

Driven by steep cost declines in PV equipment, solar is now on a par with wind energy and will soon become the cheapest form of energy in developing nations, according to the Climatescope 2016 report from Bloomberg New Energy Finance (BNEF).

In recent tenders, solar is already out-competing fossil fuel-based projects in terms of price, said the report, which covers the 58 Climatescope countries, all regarded as developing nations in Africa, Asia, the Caribbean, Latin America and the Middle East.

Average capital expenditure (capex) for PV projects in such countries during 2015 stood at US$2.15 million/MW, rapidly approaching average wind capex of US$2.02 million/MW, as seen in the following table:

BNEF also noted that the fulcrum of clean energy development has now shifted from the world’s northern countries to the south.

This year, the 58 Climatescope countries saw more renewables investment than the well-developed Organisation for Economic Co-operation and Development (OECD) countries, with US$154.1 billion and $153.7 billion invested respectively. Climatescope countries also installed more renewables – largely driven by China – with 69.8GW deployed versus 59.2GW in OECD countries.

An eleven-fold growth in PV investment in Climatescope countries from US$6.4 billion in 2010 to US$71.8 billion in 2015 has also been fuelled by the steep reductions in solar equipment costs.

The report stated: “Among all clean energy technologies, PV has seen its costs fall fastest and furthest over the last decade. This has allowed capex for projects in Climatescope countries to drop by more than half since 2010. It has also allowed PV project developers to sell their power at lower, more competitive rates.”

However the report warned that countries with the highest penetrations of wind and solar are facing troubles with integration given the unreliable nature of the grids in many of these emerging countries.

Markets with huge potential such as Brazil, China, India and South Africa were also cited as facing major solar industry troubles ranging from payment and connection delays to serious curtailment.

On another note, the low prices have also come a long way in driving a surge in companies breaking into the off-grid solar space, attempting to bring power to the 1.4 billion people that have no access to electricity. Multiple start-ups are now active in the pico solar, mini-grid and distributed solar space. As of June this year nearly 11 million households are estimated to have pico solar systems

Graphene can now convert CO2 into liquid fuels using quantum dots

Not content with it being able to make futuristic sensors, researchers have now found a way to harness graphene to make it convert CO2 into liquid fuels.

Just a few days ago (16 December), we were told that researchers at the University of Exeter had cracked a new production method that could accelerate global supply, now we are being told there might be a way to use it to make liquid fuels.

The breakthrough was made by a team from Rice University in the US who harnessed the power of nitrogen-doped graphene quantum dots (NGDQs) to use it as a catalyst in electrochemical reactions.

In what could aid in the continued effort to remove vast amounts of CO2 in the planet’s atmosphere, the resulting reaction created ethylene and ethanol.

A number of different methods of carbon capture have been devised ranging from more natural solutions like enormous forests, to more scientifically-altered building materials.

Now using a single one atom-thick sheet of graphene, the Rice researchers split it into small dots just a few nanometres in width that on their own do nothing to alter the surrounding air, but when nitrogen is introduced, the resulting chemical reaction turns it into an electrocatalyst.

However, why the chemical reaction of the nitrogen and carbon is able to turn CO2 into liquid fuels actually remains something of a mystery.

While copper has been used as the main element within similar electrocatalyst reactions when making liquid fuels, this new NGDQ method was almost identical to the efficiency of the bulkier copper material.

Graphene dots

Not ready for large scale production

The team’s findings showed that it reduced the amount of CO2 in the contained space by as much as 90pc, while converting 45pc of this into relatively small quantities of ethylene and ethanol.

As lead author of the study published in Nature Communications, Pulickel Ajayan said of this latest discovery: “One of our questions is why this doping is so effective. When nitrogen is inserted into the hexagonal graphitic lattice, there are multiple positions it can take. Each of these positions, depending on where nitrogen sits, should have different catalytic activity.

“So it’s been a puzzle, and though people have written a lot of papers in the last five to 10 years on doped and defective carbon being catalytic, the puzzle is not really solved.”

Ajayan and his team admit however that this process has been found to be far from being ready for any large-scale use, but further research will increase the size of the project to see whether more nitrogen will yield more liquid fuels.

Fraunhofer ISE develops software to analyse c-Si solar cell-to-module power losses

Fraunhofer ISE develops software to analyse c-Si solar cell-to-module power lossesThe software tool assists in analyzing potential yields, thus enabling PV manufacturers to determine how new materials or concepts would affect module efficiency. Image: Fraunhofer ISE

Fraunhofer ISE has developed a new software tool that determines the cell-to-module (CTM) effects that occur when solar cells are integrated into a module. The SmartCalc.CTM software enables manufacturers of PV modules and materials to optimize the assembly and material combination in a PV module before fabricating a prototype. SmartCalc.CTM is based on a simulation model which has been published and is under development at Fraunhofer ISE since 2008.

Problem

c-Si cell-to-module (CTM) power losses vary according to a complex number of interactions that can limit the overall performance potential of PV modules. The PV industry makes significant investment in improving solar cell efficiency but in order that PV modules benefit from the advances in cell efficiency, the cell-to-module integration process must be performed reliably with low losses.

Solution

The SmartCalc.CTM software starts with the cell power, calculating the optical losses and gains (e. g. reflection), electrical losses (e. g. due to resistances) and the geometrical losses (inactive areas) in solar modules. The software tool assists in analyzing potential yields, thus enabling PV manufacturers to determine how new materials or concepts would affect module efficiency. In the model, the interaction between components and process steps are optimized in such a way that the best possible module – with the highest power or the maximum efficiency under the given boundary conditions can be achieved. The software also offers added value in that it can quickly analyze the interplay between the influencing factors for a module design and present these in a clear manner. The underlying models in the software provide detailed yet flexible control, while the properties of solar cells, encapsulation material or module glass can be adapted easily. The software can also be used to optimize costs. For example, different less-expensive materials can be compared and evaluated with respect to the module’s performance efficiency.

Applications

Simulation of c-Si cell-to-module (CTM) power losses.

Platform

SmartCalc.CTM is based on a simulation model which has been published and is under development at Fraunhofer ISE since 2008. The software has a user-friendly interface with an accompanying operating manual. As well as the software license, the team at Fraunhofer ISE offers consulting and R&D support for analyzing and optimizing the simulation results. The software is continually developed in order to keep pace with future module technology developments.

Availability

December, 2016 onwards.
