SECI invites bids for 2,000 MW solar project with energy storage system

State-owned SECI on Thursday invited bids for setting up a 2,000 MW solar project with co-located energy storage systems in India.
In February, the Central Electricity Authority (CEA) issued an advisory on co-locating energy storage systems with solar power projects, a move aimed at enhancing the cost efficiency and stability of the grid.
As per the bid document on the SECI website, the selection of a solar power developer (SPD) for the Inter-State Transmission System (ISTS) grid-connected project with 1000 MW/4000 MWh Energy Storage Systems (ESS) will be under a tariff-based competitive bidding (SECI-ISTS-XX) process.
Solar Energy Corporation of India Limited (SECI), under the Ministry of New and Renewable Energy (MNRE), is a nodal agency for auctioning renewable energy projects.
The last date to submit online bid is July 22, and for offline it is July 24, 2025. The bids will be opened on July 25.
"The projects shall be located at the locations chosen by the bidder/SPD at its own discretion and cost, risk and responsibility," the document said.
A single project can be set up at multiple locations with different delivery points. The ESS component needs to be co-located with the project. However, in case of a project at multiple locations, the ESS needs to be co-located with at least one of the components, it said.
Under the special condition of the bid, "ESS of at least 0.5 MW/2 MWh capacity for 1 MW project capacity shall mandatorily be installed as part of the project. It is clarified that ESS charged using a source other than solar power would not qualify as solar power".
As per the National Electricity Plan published by the Central Electricity Authority, in order to integrate the 364 GW of solar and 121 GW of wind capacity by 2031-32, India would require 73.93 GW/411.4 GWh of storage capacity (26.69 GW/175.18 GWh from PSP - Pumped Storage Project - and 47.24 GW/236.22 GWh from BESS).

ACME Solar inks pact to supply 250 MW electricity from RE project in Rajasthan

New Delhi: ACME Solar Holdings on Friday said it has inked a pact with state-owned NHPC to supply 250 MW of electricity from a renewable energy project in Rajasthan. The power purchase agreement (PPA) has been signed at a tariff of Rs 4.56 per kWh for a minimum annual Capacity Utilization Factor (CUF) of 40 per cent and to meet 90 per cent of peak power requirement of 4 hours daily, according to a company statement. ACME Solar Holdings Ltd (ACME Solar) signed a 25-year PPA with NHPC Limited, a AAA-rated central government enterprise, for its 250 MW Firm and Dispatchable Renewable Energy (FDRE) project in Rajasthan, the company said. This PPA marks a significant step in strengthening ACME Solar's footprint in the FDRE space while supporting India's clean energy ambitions through an innovative mix of solar, wind, and battery storage technology. The project will be connected to an ISTS (Inter-State Transmission System) substation for which connectivity is already in place. The requisite approval under section 63 of the Electricity Act 2003 for adoption of tariff has been issued by CERC (Central Electricity Regulatory Commission) on June 19, 2025, the company said. With this, the company's PPA-signed portfolio stands at 5,130 MW, of which 2,826.2 MW is already operational, and the balance is under various stages of implementation. ACME Solar's overall portfolio comprises 86 per cent offtake with central government enterprises and the remaining 14 per cent with State discoms. The company is an integrated renewable energy player with a diversified portfolio of 6,970 MW spanning solar, wind, FDRE and hybrid solutions. PTI

Pakistan army chief Asim Munir courts US opinion makers amid bid to reset strategic ties

ISLAMABAD: In a bid to recalibrate Pakistan's global narrative and bolster ties with Washington, Field Marshal Syed concluded a series of high-level engagements in the United States, meeting senior American scholars, strategic experts, and international media representatives during an official visit to Washington DC, the Pakistani military said on Friday. Tired of too many ads? go ad free now In a carefully choreographed diplomatic offensive, Munir interacted with leading think tanks and policy institutions, offering what officials described as 'Pakistan's principled perspectives' on evolving regional and global dynamics. His engagements underscored Islamabad's renewed focus on international outreach amid a shifting geopolitical landscape in South Asia. The army chief reiterated Pakistan's commitment to regional stability, counterterrorism, and a rules-based global order, pitching the country as a responsible actor in an increasingly multipolar world. Munir spoke at length about Pakistan's counter-terrorism strategy, highlighting military operations such as Maarka-e-Haqa and Operation Bunyanum Marsoos. He reminded his audience of Pakistan's role as a frontline state in the global war on terror, citing the 'immense sacrifices' borne by its security forces and civilians. Without naming India, Munir warned against 'regional actors using terrorism as an instrument of hybrid warfare' – a familiar refrain in Pakistan's diplomatic lexicon referring to its neighbour. While not new, the accusation resurfacing in the US capital, signalling Pakistan's intent to shape the security discourse in South Asia. Munir also showcased Pakistan's economic aspirations. He pitched the country's untapped potential in IT, agriculture, and mineral wealth, calling on global stakeholders to invest in these 'engines of shared prosperity'. From foreign policy to economic diplomacy, Munir portrayed Pakistan as a country pursuing dialogue, diplomacy, and international law — an image Islamabad has been keen to project as it seeks to distance itself from past reputational baggage. Tired of too many ads? go ad free now Discussing Pakistan-US relations, Munir called for transforming the historical security-centric engagement into a multidimensional partnership grounded in strategic convergence and mutual respect. He acknowledged past cooperation on counterterrorism and economic development but pushed for a broader framework of engagement. According to Inter-Services Public Relations (ISPR), the army's media affairs wing, participants appreciated the candid nature of the discussions and acknowledged Pakistan's efforts to maintain regional stability. The meetings were seen as a trust-building exercise amid evolving US priorities in the Indo-Pacific region and growing scepticism over Islamabad's commitments. The visit comes at a time when Pakistan is striving to reset ties with major powers, especially after its recent economic crises and shifting regional alignments. With India drawing closer to the US and Afghanistan remaining volatile, Islamabad is attempting to reposition itself as an indispensable — if complicated — regional player.
