SOLROS is a program for decarbonization of Tier 1 factories through solar energy. Icebug runs the program in collaboration with a well-known Renewable Energy partner.

Who can join?

The program is for brands manufacturing in Vietnam. Factories must be big enough for 1,000 kWp installation.

Why join?
It is free - and you will save both money and emissions. Also, factories gain energy independence.

How does it work?
Factories can buy solar as a service, writing a Power Purchase Agreement for 15 or 20 years, where they commit to buy the electricity that the solar system delivers. The solar company then takes care of the financing, all the permits, the construction, the service, and system maintenance, guaranteeing the output. There’s also the option of buying the system turn-key, but all factories in the pilot are opting for PPA. To repeat, with the PPA, factories need to make zero investments, and they will start saving money immediately.

Is it effective?
Solar rooftops can cover between 25% and 70% of the electricity needed for the factories assessed. Switching from fossil to solar through this program is quick, easy, and free.

Background
The World is on a carbon budget, and to stay within a reasonable chance of avoiding climate disaster, we need to halve greenhouse gas emissions by 2030 by lowering them progressively on the way there.

The core of the climate crisis is burning fossil fuels. Most fossil fuels are burnt for energy production. When looking into our footprint, well over 85% of total life cycle GHG emissions happen before products leave the factory gates. By switching materials, we would end up short of a 50% emission decrease – material changes also require long testing times, are often costly, and have other trade-offs.

Icebug’s production is mainly in Vietnam, 99% of Tier 1. The Vietnam grid is about 70% fossil source, with growing energy demand and even coal is increasing. While Vietnam also has a lot of sunlight.

What Icebug set out to do
Decarbonize the supply chain and switch to renewable energy sources.

What we found out
Heat is difficult, electricity is straightforward. Tier 1 factories are not the most prominent hot spot, but they still have a significant impact: around 10% of apparel/footwear total emissions. Tier 1 is also the logical starting point, as it’s where we have the most leverage.

The challenge we faced: We were no experts in solar energy, nor were the factories we worked with. How do we do it? Is it possible with national and local regulations? What does it cost? Who pays for it?

(Boilers are a real hot spot. For all dyeing, we have switched to low impact: Solution dye (which also saves a lot of chemicals and water) or sublimation print, for steam-based boiler system outsole factory has switched to LNG and bio-based fuel – not a decarbonization solution but an impact improvement compared to coal)

What Icebug did
Together with four US apparel brands, we co-financed a Clean Energy Investment Agency lead pilot for solar rooftops at Tier 1 factories (CTM for apparel and assembly for footwear) in Vietnam. The idea was to achieve an economy of scale by collecting several factories simultaneously, making a group request for proposals, and making the process of assessing the potential of solar and finding the best solution provider easy for the factories.

The result of the pilot at this point
21 months after starting discussions with CEIA and 14 months after the pilot started, 17 competing bids have been evaluated, and the best bidder has been selected. Nine factories in Vietnam are now in the final contract negotiation process for installing solar rooftops. Three of them are factories that Icebug works with – all our Tier 1 factories in Vietnam.

Solar rooftops can cover between 25% and 70% of the electricity needed for the factories assessed. The estimated climate impact for Icebug’s factories is more than 5,000 tonnes CO2e saved/year. In perspective, Icebug’s total estimated emissions last year were less than 4,000 tonnes CO2e. This part of the emission cuts is up to 50% or the 10-15% that is Tier 1 for us, so our product carbon footprint will decrease 5-7,5% on a style level.

The case for the factories:
- Lowered emissions (20-50%)
- Increased energy independence
- Lowered cost (immediately and without any investment needed)

Factories can buy solar as a service, writing a Power Purchase Agreement for 15 or 20 years, where they commit to buy the electricity the solar system delivers. The solar company then takes care of the financing, all the permits, the construction, the service, and system maintenance, guaranteeing the output. There’s also the option of buying the system turn-key, but all factories in the pilot are opting for PPA. To repeat, with the PPA, factories need to make zero investments, and they will start saving money immediately.

Examples from the offer:
Factory 1: Saving 3,286 tonnes CO2e/year / 21% of electricity – cost saving 10-20%
Factory 2: Saving 1,041 tonnes CO2e/year / 53% of electricity need – cost saving 30-35%
Factory 3: Saving 718 tonnes CO2e/year / 43% of electricity need – cost saving 30-35%
(The difference are mainly due to location, the increased solar radiance in the south give a higher system efficiency)

The case for the brand(s):
- Lowered product carbon footprint without trade offs.
- Being a forerunner to switch to renewables.
- Handing factories a cost decrease.
- A potential renewable investment case.

The next step
Speed is of essence to tackle the climate crisis. We need to cut emissions immediately. The most efficient way we have seen to do that is by installing solar energy at Tier 1 factories in Vietnam. As a result of the pilot, we have identified the most suitable solar energy partner for factories.

They have been selected in a thorough screening and bid competition by clean energy experts, evaluating them as solar vendors on Overall qualifications (25%), Technical proposal (25%), Financial proposal (40%), and Proposal quality (10%). The group approach of the pilot had the downside of everybody having to move at the same speed, which means the speed of the slowest. The upside is the leverage of the economy of scale. But the solar company winning the bid has now agreed to make these offers the framework for a Vietnam and South East Asia solar rooftop program where additional brands and their factories can enter on the same terms.
What took Icebug 12-18 months and $55K can now be done by other brands in 1-2 months without cost.

Factory requirement
- Big enough for 1,000 kWp installation (not the smallest factories, but medium-sized will qualify)
- Suitable roof
- Financial stability (or a bank guarantee)

Brand requirement
- Top management buy-in and willingness to lean in, skin in the game from the brand (as we have seen that the ease of business as usual has been the primary stopper)
We want to start feeding hot prospects into this program during the fall. Participation fee: $5K/brand/factory, which will be repaid if the pre-feasibility study shows that it’s impossible to save money with solar or when the contract is signed.

Let’s be forerunners in decarbonizing the supply chain!
