Efficient Electric Pressure Cookers (EPCs)

Why to choose this solution?
The continued large-scale use of wood-based fuels is deemed to be unsustainable due to the significant health and environmental impacts associated with wood harvesting and use. The current unsustainable production and use of woodfuel for cooking undermines household food security, income, exposes women and children to indoor air pollution, creates high barriers for economic development, hence a poverty trap. Uses of efficient electric pressure cookers (EPCs) address most of these shortcomings of wood fuels. EPC is the fastest, cleanest and cheapest way of cooking.
Savings per day or production:
EPC is approximately seven times cheaper than kerosene, ten times cheaper than gas and thirteen times cheaper than charcoal for boiling heavy foods based on existing market prices in Tanzania.
Cost in money and in own time to construct:
EPC costs about twice as much an electric hotplate. Market price in Tanzania range from 180,000 to 250,000 Tsh (USD 77 to 107) for quality EPC with capacity of 4, to 6 litres depending on a point along the market chain the appliances are procured by an end-user.
About 5 to 6 years.
Maintenance needed:
Requires replacement of rubber seal on the lid after being used for some time.
Resources needed in use:
Electricity from grid, mini-grid and solar home systems can be used.
Problems and limits:
Use only one type of pot. Not suitable for some food like nyama choma, chapatti and deep frying. Looks complicated at first.
Where and how can you get it or make it?
"Most of them imported from China, Japan, South Africa, Europe, etc. and distributed by various companies including SESCOM in Tanzania. To produce EPC you need investment to establish a factory."
Skills needed to produce, install. maintenance, use:
EPCs are manufactured in factories and special engineering knowledge is required. Training is required to be able to provide after sale services. Simple training/introduction is required on how to use EPC.

How to maintain it:
Climate effect (if any):
Saves forests by providing alternative source of clean cooking solution. There is avoided emissions from combustion of biomass.
Where it is used and how many users are there?
Mostly used in households in Dar es Salaam city, Dodoma, Kilimanjaro, Arusha, Mwanza in Tanzania. Also used in Saranda and Londoni village of Singida region, Changombe village in Gairo by customers with mini-grid electricity operated by the PoweGen company.
Why is it successful?
Awareness and capacity building has contributed a lot in addressing the knowledge gap which is existing in the country. Most of the people do not consider electricity as a cooking fuel as they perceive it to be expensive. After discovering the use of EPC is the cheapest way of cooking, adoption rate has increased sharply.

How is it delivered and by whom?
Main actors of EPCs include: Importer, distributors, retailers and end-users. The EPCs are manufactured in different countries and are imported by local entrepreneurs or owners of supermarkets in Tanzania. The local dealers either supply EPCs to urban end-users through distributors who have been selling them to retailers. The retailers may either transport them to the remote areas connected with electricity. Some of retailers are mini-grid developers who intend to introduce new electric appliances to the mini-grid customers. Main actors: SESCOM (a social enterprise promoting, importing and marketing EPCs), TaTEDO (focuses on support services provision i.e. research, awareness raising, capacity building, market development and lobbying for enabling environment for EPCs under the support of MECS programme financed by DFID). SESCOM imports EPCs directly from manufacturers and take to the agents and end users.
Successful financial model
EPCs are delivered with pay-as-you-go financing model to the mini-grid customers whereas customers who can not pay the whole charges once are linked to micro-financing institutions which facilitate them to make payments on installment basis.
What policies and strategies helped the success?
Rhe National Energy Policy (2015) promotes energy efficiency and alternative energy to biomass for cooking. Micro finance Policy (2017) creates an enabling environment for efficient and effective microfinance sub-sector in the country that serves the needs of the low-income individuals, households and enterprises. Other supportive strategies and regulatory frameworks include SE4ALL Action Agenda (2015), Electricity Act of 2008, Rural Energy Act of 2005 and Environmental Management Act 2004.
