Laser mapping technology — where aerial light pulses are directed at the ground from an aircraft — recently helped archaeologists discover an ancient Mayan city under the jungles in Guatemala. In Bengaluru, the same technology — light detection and ranging (LiDAR) — is being used, but for a different reason.

Over the fortnight, a helicopter armed with LiDAR system will fly across the city, mapping its potential to generate rooftop solar energy.

The initiative, which is based on a 2016 agreement of Bangalore Electricity Supply Company (Bescom) with the Centre for Study of Science, Technology and Policy (CSTEP) and Karnataka Renewable Energy Development Ltd. (KREDL), finally took flight on Sunday at Jakkur aerodrome.

Bescom has commissioned the mapping in a bid to meet its target of generation of 1,000 MW of rooftop solar energy by 2022 from Bengaluru alone.

The aircraft will cover an approximate area of 1,100 sq. km, generating high resolution images of rooftops of buildings in the city. The mapping will be carried out by CSTEP and the data generated will be submitted to the Energy Department.

The LiDAR technology will send pulsed laser light on to the rooftop of a building and translate the reflected light into data points. Based on objects such as trees surrounding the rooftop, shadow-free area available for solar power generation will be calculated and an estimate will be arrived at as to the capacity of solar generation of each building in the city, said officials.

The data mapping will continue for a fortnight for about two hours every day.

Saptak Ghosh, research scientist, CSTEP, said they had to take permission from six government departments and ensure that they were not capturing data of sensitive installations.

“Initially, we had proposed 1,100 sq. km to 1,200 sq. km. Around 100 sq. km of sensitive building were blotted out by the Ministry of Defence. As soon as we collect the data, we will send it to the MoD for vetting. We are likely to get back that vetted data in three months. Later, developing the tool based on this data will take another two months,” he said.

A senior official from the KREDL has been designated as the security officer to oversee that the aircraft flies only in permitted area.

Once the data is collated and presented to the Energy Department, residents of the city will be able to check the capacity of solar power generation of the rooftops of their respective buildings, when they log in to the Bescom website to pay electricity bill. The system will send an OTP to the user to cross verify whether the particular rooftop belongs to the property owner.

While maintaining a stable outlook on the solar power sector, domestic rating agency India Rating has revised upwards the outlook on the wind power sector to stable from negative for FY19 but has maintained its negative outlook on the thermal power sector.

Citing lack of visibility for tying up long-term power purchase agreements, the agency has maintained its negative outlook on the thermal power sector for FY19.

The agency expects favourable environment for the wind and solar energy sectors as bids are being driven by Central agencies and power purchase agreements (PPAs) are becoming favourable to developers in terms of addressing grid curtailment and termination issues.

"Development of guarantee funds by states/bidders, incentives to local solar panel manufacturers and exploring of wind-solar hybrid projects and offshore wind projects indicate a sustaining growth momentum in renewable power," it said in a report today.

India Ratings feels uncertainties in solar panel costs, unpredictable behaviour of distribution companies (discoms) and operational troubles from wind turbine manufacturers need to be addressed by renewable developers.

"We believe that avoidance of downtime of solar and wind plants are critical in ensuring the predicted internal rate of returns," the report said.

According to the agency, adequate liquidity back-ups and counterparty risks as the most critical factors for renewable projects.

It, however, maintained a negative outlook on the thermal power sector for FY19, due to lack of visibility for tying up long-term PPAs.

"Existing excess power tie-up of discoms and PPAs already signed with central and state sector generating companies for buying power from 40GW under construction thermal plants, preclude the need for purchasing power from private thermal plants under long-term PPAs," it reasoned.

India Ratings feels excess power tie-up, ahead of requirement, increases the power purchase costs for discoms.

"Also, thermal plants remain vulnerable to coal and water availability; thus certainty in these two linkages is hard to come by," it added.

Meanwhile, the agency has maintained a stable outlook on transmission projects owing to high project availability and a stable receivables period for interstate transmission assets.

As many as 41 government/aided schools in the state would be getting uninterrupted power supply by the end of the current academic year.

Agency for non-conventional energy and rural technology (ANERT) in association with State Energy Management Centre is taking steps to set up solar power generation units at these select schools.

"The schools have been identified by Energy Management Centre. The schools will have to spend Rs 80,000 for setting up a 2kW solar power unit on their premises. The rest of the expense to set up the solar generation unit would be borne by ANERT," ANERT director R Harikumar said.

The school's share for the project is met through the contribution of PTA, MLA, MP funds or from the assistance of local self-governments. The scheme is part of a package introduced by ANERT for schools. As per this, ANERT would provide 50% subsidy to one school each in 41 educational districts to set up 2kW solar unit and a portable biogas plant with one cubic metre capacity.

The Energy Management Centre had turned as many as 500 government and aided schools energy efficient during the last academic year, by giving them assistance to replace all electrical equipment with energy efficient (star rated) ones. "The 41 schools being shortlisted are from among the 500 energy efficient schools. As of now, steps have been taken to install 2kW solar units in 21 schools. A tender has been floated to identify agencies interested in setting up the units as per the set specifications. The units would be installed in other schools before the end of the current academic year," EMC director Dhareshan Unnithan said.

Once the plant is set up, the schools would not have to worry about the power outages in the KSEB grid. It was based on the request from the schools themselves that ANERT decided to install solar units with storage battery facility. The average life for solar panels is assessed at 25 years. However, the units would continue to run even after 25 years.

Power produced from wind and solar projects will become viable and more attractive for discoms as the government last week waived off inter-state transmission charges for wind and solar projects commissioned till March 2022, in a bid to encourage the use of power generated through these sources.

"For generation projects based on solar and wind resources, no interstate transmission charges and losses will be levied on transmission of the electricity through the inter-state transmission system for sale of power by such projects commissioned till 31st March 2022," said a letter issued by the power ministry last week.

The move will take away future possibilities of additional cost to discoms, encouraging them to purchase power produced from wind and solar projects, the industry said. "This should give discoms good reasons to meet their renewable purchase obligations," a renewable energy developer said on condition of anonymity.

The revised Tariff Policy 2016, states that “in order to further encourage renewable sources of energy, no interstate transmission charges and losses may be levied till such period as may be notified by the Central government on transmission of the electricity generated from solar and wind sources of energy through the inter-state transmission system for sale”.

For wind and solar projects, the existing waiver was previously applicable to projects commissioned up to March 31, 2019 and December 31, 2019, respectively.

“This should also help more people go for the next round of bidding because projects will look more viable,” said the person cited above. “This should give more impetus. Tariffs are already pretty low, and this should come as a relief.” Solar and wind power tariffs in the last few months have already reached grid-parity, helping it compete with thermal power. With the transmission charges waived off, it will make selection of location for these projects more efficient, experts say.

“The waiver is very positive for power utilities, who can now source wind and solar power from the few resource-rich states,” said Kameswara Rao, leader-energy, utilities and mining at PwC India. The policy is very positive for renewable companies as they can sell to all obligated entities (that is, all who are required to meet renewable purchase obligation) and not just power utilities, Rao pointed out. “Also, given the long time frame, renewable companies will try to set up multiple mega projects,” he said.

The waiver applicable for 25 years since the date of signing a power purchase agreement (PPA), will be allowed to only those solar and wind projects that are awarded through competitive bidding process.
