With a number of new power-intensive and IT industries proposed to be established, Bhutan’s home demand for power is projected to greater than double within the subsequent two years, and its winter power deficit will worsen, officers on the Division of Business instructed The Third Pole. With hydropower unable to fill the hole, in current years Bhutan has been trying to diversify its power sources.
“
I consider that electrical energy generated by hydro power continues to be extra environment friendly, cheaper and cleaner than harnessing the power from the solar.
Yeshey Dorji, environmental activist, Rangjung CS Trashigang
Photo voltaic power has develop into aggressive
Solar energy is seen as a fast method to meet the rising demand for electrical energy. The federal government plans to finish the nation’s first giant photo voltaic plant, the 17 MW challenge in Sephu, Wangduephodrang, inside 18 months from when it begins development later this yr.
Phuntsho Namgyel, director of the Division of Renewable Power (DRE), mentioned that photo voltaic crops might be commissioned and constructed inside a brief time period – particularly in contrast with the years and even many years it could take to develop hydropower.
Enhancements within the know-how additionally imply it’s now cheaper and extra dependable. “At this time photo voltaic power has reached grid parity with hydropower, which means the per-unit value of electrical energy is nearly equal to that of hydro,” Namgyel mentioned.
The DRE estimates that the worth of electrical energy from the Sephu plant will probably be round BTN 3 a unit. That is decrease than the worth it prices to export electrical energy to India from the 720 MW Mangdechhu hydroelectric challenge, which is BTN 4.2 a unit.
Globally, the price of growing photo voltaic power has decreased considerably prior to now decade. In line with the Worldwide Renewable Power Company (IRENA), the worth of photo voltaic panels has dropped by nearly 90 per cent since 2009.
Earlier obstacles have been overcome
A earlier impediment to rolling out solar energy within the Himalayan nation has been a scarcity of expert staff and issues importing supplies – significantly in the course of the pandemic. Nonetheless, following the comfort of Covid-19 restrictions, many of those points have been resolved, Phuntsho Namgyel claimed.
A number of years in the past, photo voltaic panels couldn’t generate electrical energy throughout cloudy days. Now, Namgyel defined, they’ll take in ultra-violet rays even when the solar isn’t shining, changing nearly 22 per cent of daylight in contrast with 17 per cent a number of years in the past.
Photo voltaic can also be simple to develop, Namgyel added. Not like hydropower, “there is no such thing as a query of geological surprises” as photo voltaic doesn’t require tunnelling, subsurface digging and doesn’t straight pollute or injury the setting.
A giant remaining problem for the tiny landlocked nation is the necessity for large tracts of land to put in photo voltaic panels. As an illustration, the photo voltaic plant in Sephu would require round 26 hectares of land, which is almost 50 soccer pitches.
Not everybody The Third Pole spoke with was satisfied by the plans. Yeshey Dorji, an environmental activist, identified that the necessity to retailer electrical energy in batteries comes with its personal environmental value. At present, batteries are sometimes disposed of unsafely on the finish of their helpful life.
“I consider that electrical energy generated by hydro power continues to be extra environment friendly, cheaper and cleaner than harnessing the power from the solar,” mentioned Dorji. Declaring that injury has already been executed to the Wangchu river basin, he mentioned a storage dam on the Wangchu river could be a greater method to meet the winter electrical energy shortfall.
Rooftop photo voltaic and feed-in tariffs
Not like wind and hydropower, photo voltaic panels don’t require specific situations to work and might be put in on the rooftops of homes throughout the nation. The Ministry of Financial Affairs is finishing up a pilot challenge to put in photo voltaic panels on 300 properties, enabling them to promote surplus energy to the nation’s grid.
Phuntsho Namgyel mentioned households with photo voltaic panels can develop into “prosumers”, which means they are often each the producer and shopper of power.
Nonetheless, officers from the Division of Renewable Power mentioned this can require altering insurance policies and rules. A draft regulatory framework has already been ready and the 2013 Various Renewable Power Coverage revised. It will include the ideas that decide tariffs for promoting energy to the grid. Ultimately, although, the Bhutan Electrical energy Authority will formulate the nationwide regulation to find out the tariff.
As soon as the brand new feed-in tariff regulation is in place and power from photo voltaic is fed into the grid, extra energy might be bought to India and imports might be minimised. At present, Lokhnath Sharma mentioned, the worth of imported electrical energy is extraordinarily unstable, various from BTN 2 per unit to as excessive as BTN 10 per unit.
Wider power sector reform
In 2020, hydropower crops generated greater than 11,000 million kWh of electrical energy, in response to the data of utility firm the Druk Inexperienced Energy Company. Within the coming years, Bhutan will proceed to develop hydropower, Sharma mentioned. Which means that even the ramped-up 300 MW photo voltaic goal will nonetheless be a tiny proportion of the general power combine.
Sharma mentioned there may be an pressing want to alter the best way hydropower initiatives are developed, as they usually lead to large value escalations and delays that don’t make financial sense.
The minister additionally confused the necessity for a typical regional grid in order that Bhutan can promote energy to its neighbours. To allow this, there must be a brand new or revised mannequin of charging for energy to maintain electrical energy costs aggressive, the minister mentioned.
As Bhutan adapts to altering market dynamics and strikes to diversify its power combine, Sharma mentioned the federal government can also be contemplating inexperienced hydrogen as a possible space of funding. The gas can be utilized within the transportation sector to scale back fossil gas dependency. Earlier than the pandemic, Bhutan imported fossil gas price over BTN 10 billion a yr on a median, in response to the Ministry of Finance.
Whereas extracting hydrogen from water is an energy-intensive course of, in Bhutan the power might come from renewable power and thus produce inexperienced hydrogen.
